Free Milky Way NightScapes Photography Lectures


 Free Milky Way NightScapes Photography Lectures for Camera Clubs and Local Photography Groups.


Next presentation at:

Sedona Camera Club

Christ Lutheran Church, 25 Chapel Road, Sedona, AZ 86336

Feb 23, 2026 • 6:00pm • In-person

(One-time visitor's fee of $5.00 if you're not a club member)


Although I've been paid handsomely to give dozens of presentations over the years at photography conferences throughout the world, I often "give back" to our photography community with free lectures to local photography groups and camera clubs.

A typical astro-landscape photography presentation, with PowerPoint slides, runs about 45 minutes to an hour, followed by up to 30 minutes of Questions and Answers from the audience. My only pay-back is that the hosting organization allow me a 2-minute advertisement about my Milky Way NightScapes eBook, which can be purchased online (often with a special discount code for members of the hosting organization).

Typical Presentation Methods to Your Group. Your Choice Between:

  • Zoom option 1: You provide the live Zoom connection. You are free to record the presentation and share it later to members who could not attend. Cost: No charge from me.
  • Zoom option 2: I provide the live Zoom connection. I will also record it and post it to YouTube, where your member can access it after the live Zoom meeting. Cost: No charge for my presentation; however, there is a fee of fifty dollars to help pay for Zoom and uploading costs.
  • In-person: I will come to your club or organization and make my presentation. Cost: No charge for my presentation; however, you must pay for my round trip transportation costs from Salt Lake City, UT USA; and lodging costs in your city.

Email to inquire about my available dates or to ask questions: orida70@gmail.com 


Here are a few recorded examples of presentations I've given:


Promoting Your Camera Club

When I come to your area, I often help promote your local organization or camera club. Here, I'm on a local TV program in Florida promoting a presentation I'm going to give that weekend at a local camera club. My lecture was free to camera club members. The club charged a nominal fee to the general public—helping to bring in money to support the club's future programs. I also use my domain name "NightScapeEvents.com" to link up to the club's website or any other local astrophotography event I'm trying to help promote (that domain name goes to this blog page when there is not a current event scheduled).

Image Critiques - Portfolio Reviews - Judging

When I do photography lectures I’m often asked to do image critiques as well. This is where each of the club or group members can submit a few digital images beforehand and have me critique the images in front of the whole group. The group usually benefits just as much as the photographers being critiqued.

More than nightscapes: In some gatherings I’m asked to do competition judging or portfolio reviews. In all cases, these images cover a wide variety of subjects and genres. That’s because I’ve not only had experience in nightscape photography, but I’ve spoken and judged multiple times for the Professional Photographers of America (and Canada), the PSA, and for the American Society of Media Photographers (ASMP).

My professional photography career has spanned over three decades in magazine, commercial, industrial, portrait and fine art photography. Besides being a full-time photographer, over the years, I've also been the CEO of a stock photo agency, a fine art printing company and an art gallery.


Royce has been doing magazine and commercial photography for over three decades.

Tips for taking Nightscapes from a drone

A DJI Mavic 3 drone photo, taken above the Outeniqua Pass foothills in South Africa by Agnieszka Taggart

 Written by Agnieszka Taggart

Agnies is a licensed drone pilot and instructor in Johannesburg, South Africa.

Drones are becoming more popular among photographers so it’s no surprise that with the improving specifications, they are also becoming usable in night sky photography.

There are couple things to consider though.

One is the legal side of flying drones at night as some countries only allow drones during the day or with special permissions.

The second one is drone capability to take long exposure photos. Modern drones are quite good at holding the position, but what’s considered good in the world of drones, may not always be good enough in terms of optics and photography.

Typically, the longest exposure from a drone is 8 seconds, but it does not mean that all your exposures taken at 8s will be usable - this is to the fact that even within this rime, the drone will have some movement, usually caused by wind.

Drones typically use the below systems to hold the position:

  • GPS: modern drones use as many satelites as they can detect, 12-15 satelites is needed for good position lock, sometimes even more. Accuracy increases with number of available satellites
  • Compass/ gyroscope: this defines which way the drone is pointing 
  • Visual sensors: many drones are equipped with visual sensors for position hold. The sensors scan the ground and register the image  - the more contrast and illumination, the better the visual position hold. 

In order to get good position lock, hover over something bright and with good contrast - you might want to put a torch on a landing pad.

Accuracy of visual sensors decreases with height, so do not fly high if you don’t have to. In most cases, you only need to clear the height of the roof and trees, so 10-15m above the ground should be enough. Wind is also weaker close to the ground and increases and often changes direction as you mice up.

* Do not take off from a car roof, there is a lot of interference from car electronics that might affect the accuracy of the drone compass. If you chose to hover above a car, take off from a different spot and move over once you reach required height.


Based on the above, you might need to adjust your regular work flow for all types of night time photography.

1) Single exposures

As mentioned, you will be limited to 8 seconds. That’s short, so in order to have usable image, you will need to dial up your ISO. I typically use ISO3200 on my Mavic 3. In case of single exposures, sensor size is the key. You might get away with 1 inch sensor, but 4/3 will produce better results. Take many shots and choose best - they will not all be usable. The types of photos that work well in this situation are naturally contrasty and well illuminating landscapes (snow, sand, water, pale rocks such as sandstone and dolomites), landscape with busy road to capture the trailing lights and non-aggressive light painting

2) Blending and stacking

Typically you would take some shots at “blue hour” and then some night sky shots later. With this technique, it is critical to keep the drone in same position. It is extremely unlikely that you will do this with a single battery, so you will have to record the exact drone position, direction and height. You may want to create a waypoint if your drone app has this function.

3) Composites

Using drone for night time photography is challenging and you may be left with no option than to create composite. If you do, make sure that it is true to nature - check the directions and star positions. It is useful to take a shot with most prominent stars and combine it with shots from the ground. And of course ALWAYS reveal the technique.

Focus Stacking Nightscapes with Marybeth Kiczenski

 

Big Stable Lighthouse by Marybeth Kiczenski • Foreground taken during the blue hour, using several 15 second "focus stacked" exposures at f/8, ISO 800 • Sky is a 90 seconds tracked exposure, ISO 1000, f/2.8 • Sony a7iv  camera, with a Sony 24-70mm lens at 50mm.

Winter blooms at Anza Borrego by Marybeth Kiczenski • Foreground taken during the blue hour, using several 6 second "focus stacked" exposures at f/8, ISO 800 • Sky is five 1-minute tracked exposures (a total data stack of 5 minutes), f/2.8, ISO 800 • Sony a7iv astro modified camera (to visible + H-alpha), with a Sony 12-24mm lens at 14mm.

Step-by-Step Tutorial

A 3-image focus stack taken during the blue hour by Marybeth Kiczenski.

Focus stacking your night images is a great way to improve the overall image quality.  Much of the process is akin to daytime focus stacking – but with a twist.  Depending on if you are blue hour blending, or using true night images, the process may include further post processing.  

One of the most popular case uses for focus stacking involves flowers.  Flowers make beautiful foreground subjects, but with wide-angle images at F/16 – the depth of field rarely is enough for these small, yet mighty, subjects.  

Before we dive in, also note that flowers move.  They move A LOT.  The slightest of breezes can move these delicate subjects.  You may find yourself either giving up, OR doing your focus stack of the flower in blue hour – sometimes VERY early blue hour.  Basically, as soon as the directional light from the sun disappears.  The reason is you’ll need those faster shutter speeds to freeze the blooms.  

Pay attention to the weather considerations and wind.  You don’t want to miss that small window to capture still flowers!  

With that out of the way, let’s get to the task at hand.  You’ll notice here that the flowers here were taken not long after the sunset.  While I had the tripod set up in this spot from sunset to milky way, the sharpest stack was from this early evening time frame.  

Another point to consider:  what is your minimum focus distance of your lens?  As you can see here, the Sigma 14-24mm F/2.8 ART lens failed to catch the focus on the nearest flower to the lens.  But to be fair, it was basically on top of it.  If this is the type of thing that bothers you, then you’ll want to adjust accordingly.  I loved having the flowers frame the scene, so I creatively chose to live with this flaw rather than losing the top anchor flower. 

The yellow dots indicate the approximate focus points the camera chose in each of the three focus stack exposures. The lens aperture was set at f/8. An aperture of f/16 would have given greater depth of focus, but the exposure would have needed to be four times as long, which can cause flower movement, if there is any wind. If focus stacking had been done in total darkness (using an aperture of f/2.8), then a much great number of exposures would be needed to create the focus stack depth of focus (and focus for each would have been done manually).

The actual focus stacking process involves you starting on the nearest subject, and progressively shifting the focus until you reach the infinity point.  You can pick subjects from the scene to focus on, shift your lens step by step, or utilize some camera’s ability to in-camera focus stack.  This image was done with a Nikon D850 – the first camera from Nikon to have this feature built in.  The number of images you’ll need also depends on the aperture you choose. In other words, you’ll need a lot more images to complete the stack  at F/2.8 vs. F/16.  You may have to play around (if your camera doesn’t have the auto feature) to make sure you get everything in focus.  

IMPORTANT NOTE: If you are doing your focus stacking in the dark – you’ll have to manually focus on your different points.  This can be an issue if you are with a group, as the “easy” way to focus on the subject is to shine a light on it, set the focus, then turn it off.  Communication is key!  For this reason, (as well as the aforementioned weather issues), 95% of all my own complex foreground will likely be blue hour foregrounds.  There are times where this just isn’t possible, so you just deal with the parameters dealt!


After you collect all your in-field data (focus stack images and your starry night sky exposure), it’s time to do the process the focus stack:

  1. Open your best sequence in the editing software of your choice.
  2. Apply your basic edits.
  3. Save the edited images.
  4. From here, you can use Adobe Photoshop, or software such as Helicon Focus.  For images that Photoshop has issues with, I will use Helicon.  [Update: recent Photoshop updates drastically improved its built in focus stacking algorithm.]
  5. Open the files as a stack.
  6. Click on “attempt to align layers”
  7. Once the images are loaded into layers, I will then Auto-Align them.  This just insures to me that they are aligned to the best of the computer’s ability to do so.
  8. Select all the aligned layers, then click “Auto-Blend”  The Auto function typically will suffice.

The computer will then apply masking as it sees fit to make a seamless blend.  Photoshop uses depth mapping for this type of stacking.  When that doesn’t work correctly, that’s where Helicon Focus comes into play.  This program features different algorithms to figure out the focus shifting beyond the scope of Photoshop.  You can pick between these algorithms and see how it changes the stack.  

Once you are happy with your focus stacked image, save that file out.  From here we will now go into adding in the sky, and color matching the two assets to make a final composition!


PUTTING IT ALTOGETHER

At this point, you should have two main images to work with:

  1. Focus stacked foreground image
  2. Single exposure / a Stacked exposure / or a Tracked sky image

Open the focus stacked image.  From here you’ll want to apply a mask to remove the sky.  This can be a number of ways.  The easiest of which is using Photoshop’s new “Select Sky” function.  This works remarkably well for well defined horizons.  I find that it starts to struggle with trees.  Sometimes it will remove too much detail in these complex areas.  It’s always worth a try, though!  As it's the easiest method! 

If this fails, you can deploy the very powerful color-channel masking method.  This is a bit advanced, but it's remarkable – especially when dealing with trees.  Here’s the simplified process:

  1. In the layers panel, navigate to the color channels tab.
  2. Click on each channel until you find the one that separates the foreground from the sky the best. Usually this ends up being the blue channel, but not always.
  3. Copy that color channel into its own new layer.  This step is IMPORTANT, as if you don’t copy it, any changes you make will affect the master image.
  4. Use brightness/contrast to create more separation.  You want a black and white image.
  5. Use the dodge and burn tool to define the edges.
  6. Once happy, then select one of the colors – either black or white.
  7. Click back to the full color image – and click on “apply mask”.



Masked Focus-stacked foreground — ready to be blended with starry night sky image


Once the sky is masked out, then you can open your sky image.  Copy that image over to the foreground image into its own layer.  I always put the sky under the foreground.  


Now save this master file out as a new file.  This way you still have an unaltered focus stacked image, in case things go drastically wrong. 

Initial blend of foreground focus-stack and sky exposure

COLOR BLENDING

Here’s where your creativity begins to take flight!  Using the Hue/Saturation, Color Balance, and Selective color under Adjustments, start working the colors until the foreground begins to match the sky, or vice versa.  This is really a personal preference.  Blue hour images – as the name implies – are heavy in the blue/magenta tones.  Some will choose to keep with this theme, and make the night sky match the blue tones.  However, the colors of the natural night sky are not blue.  So you have to make this creative choice.

The magic is really in the color matching for creating convincing compositions.  It can take a lot of small finessing and adjustments, and practice.  

Once you are happy with the color matching, then you can take the editing further with curves, brightness, contrast, using the Nik collection, and more!

Winter Milky Way by Ralf Rohner

 

Winter Milky Way at a "Secret Beach" on the Oregon Coast © Ralf Rohner (click to enlarge) 

Nightscape photographers in the Northern Hemisphere often talk about the "Milky Way season", and bemoan that the season is "over" when winter comes. Actually, this is a misnomer. The Milky Way is always with us—summer or winter, as you can see in Ralf Rohner's beautiful panoramic view of the winter night sky.

What some less informed photographers are referring to is the absence of the "core" or galactic center of the Milky Way during the winter months. A better term might be: The "Milky Way core season" is over during the winter months. (The opposite is true in the Southern Hemisphere, when the core disappears below the horizon during some of their summer months).


"The Astrophotographer's Yin and Yang" at Mobius Arch © Ralf Rohner (click to enlarge)

This panoramic photo blend is a wonderful example of how our view of the Milky Way changes during the seasons. The photo is a blend of both Milky Way seasons, taken from the same location (Mobius Arch, in the Alabama Hills of eastern California). Ralf had this to say about the image:

Do you prefer winter or summer? Cold or warm? Dark or bright? Yin or Yang?

Yin is the dark side of our Milky Way, dominated by Orion, the hunter. As northern hemisphere dwellers, we associate this dimmer part of our galaxy with long, cold nights, but it also contains some of the most beautiful gems in the night sky, as the light fights its way back in the form of stunning red hydrogen emission nebulae, dotting the whole Milky Way band.

 For bright Yang, you have to look for Sagittarius, the steaming teapot, which points towards the galactic center, the brightest part of the Milky Way. In the northern hemisphere, this is associated with warmer but shorter spring and summer nights. Adjacent to the Milky Way core, in the border area of Scorpius and Ophiuchi, lies one of the most colorful parts of the night sky, the Rho Ophichui region. Despite all this light, one can not ignore the looming dark cloud of the Great Rift, blocking the starlight and colors in the constellations Serpens, Aquila and part of Cygnus. Ironically, this seemingly star-eating molecular cloud is home to some of the most active regions of star formation. The light once again gains the upper hand in the bright hydrogen emission nebulae of Cygnus, around the stars Sadr and Deneb.

 Thereafter, we enter the transition zone between the bright and the dark side, which is ruled by King Cepheus and his vain wife Cassiopeia.

 During a short period in spring and autumn, it is possible to see both sides in a single night. I had the privilege to be able to capture this at Mobius Arch in California.

The Yin-panorama was captured after nightfall, facing westward, and showing the winter Milky Way with setting Orion. The east facing Yang-panorama shows the rising galactic core and Cygnus, shortly before dawn. Both were merged to create this 'Yin-Yang' image, showing the entire Milky Way visible from mid northern latitudes. [The bright area in the sky, just to the right of the arch is Zodiacal Light.]

Ralf's technical information for the top photo of the "Secret Beach" will give you an idea of how he creates his nightscape panoramas:

  • Camera: Canon EOS-R, astro-modified 
  • Lens: Tamron 15-30mm f/2.8
  • Narrowband filter: IDAS NBZ filter
  • Tracker: iOptron SkyTracker Pro 
  • Sky: 6 panel panorama, each a stack of 6x 60s @ ISO1600 & 3 x 150s @ ISO6400 
  • Foreground: 6 panel panorama of 5s @ ISO400 during blue hour

Low Level Lighting BLENDS

The Milky Way above Temple of the Moon in Capitol Reef National Park, photographed with Low Level Lighting, and then blended with an additional foreground exposure (using overhead starlight) to increase foreground detail in the shadow areas.

I love doing both Low Level Lighting and starlight blends. My colleague, Wayne Pinkston and I co-authored the Low Level Lighting technique (or LLL). LLL gives one the drama or character that one can achieve with moonlight, but without washing out or lower the contrast of your Milky Way sky. Starlight blends allow you to increase foreground detail (especially in the background areas) that one cannot achieve with LLL, and many think that starlight blends look more natural, even though they are "flat" due to the overhead lighting effect of starlight. By blending my LLL exposures with the foreground portion of a longer starlight exposure, one can achieve the best from both techniques. Let me explain in this tutorial...



1. A single exposure (15mm lens on a Canon 6D • f/2.8, 15 sec, ISO 8000)

2. Same EXIF, but with my LLL, and stacked 18 times to reduce noise. I like the drama and "character" one can achieve with LLL — it's similar to moonlight, but you get to control the direction of the light, and it doesn't wash out or lower the contrast of your Milky Way sky.

3. Longer foreground exposure, using overhead starlight (f/4, 120 sec, ISO 6400, with Long Exposure Noise Reduction turned on), then blended with the sky exposure in number one. I like the detail I get in the foreground, but I often do not like the "flat" lighting this technique gives you. (One remedy is to do a Blue Hour blend rather than a starlight blend, as these twilight blends have more of from-the-side directional light.)

4. My LLL exposure (from 2.) blended with the foreground exposure from number 3. This gives me the best on both techniques: more foreground detail (from the longer starlight exposure) AND more "character" from the LLL.

NOTE: As of May 25, 2021 there is no longer any artificial lighting allowed in Capitol Reef National Park due to a new Superintendent’s Compendium.

This includes LLL (Low Level Lighting) — even though the intensity of LLL on the monument is equal to the light coming from a Quarter Moon that is about to set.

Capitol Reef now joins Arches, Canyonlands and Grand Teton National Park (and Natural Bridges Nat'l Mon.) in this artificial light restriction.


ALTERNATIVE BLENDS: Where LLL is not allowed, a blended exposure of the starry night sky (as in #1), with a longer exposure of the foreground lit by overhead starlight (as in #3), produces beautiful results. Many feel this has a very natural look. I agree; but I also think it has a flat, and somewhat drab look.

An alternative is to use a Blue-Hour blend from a twilight exposure that is taken about 30 minutes to an hour after sunset, or a similar period prior to sunrise. The advantage of a twilight exposure is that it has directional light: the west side of the sky (after sunset) is brighter than the rest of the sky, and the opposite is true for a morning twilight. When these brighter portions of the sky are perpendicular to your foreground landscape features, they produce shading and sculpturing to your landscape, giving it more interesting "character." The disadvantage of this technique is the waiting: You have to shoot your Blue-Hour exposure and wait until the Astronomical Dusk to shoot your starry night sky exposure (or shoot your starry night exposure and then wait for the morning twilight exposure). With a starlight foreground exposure, you can take that foreground shot immediately after doing your starry sky exposure. Here is a tutorial for doing a Twilight Blend...

A Blue-Hour exposure of three obelisk spires in Capitol Reef National Park. Photo taken about an hour after sunset with a Canon 6D, using a 15mm Irix lens • f/4.5, 25 seconds, ISO 800, Daylight White Balance.

Same image processed to a warmer, more natural color balance. (Some people like to keep the bluish or purplish color balance that come with a twilight or Blue-Hour exposure. I do not.)

Milky Way sky exposure taken about 1-hour later, during the Astronomical Dusk: f/2.8, 15 seconds, ISO 8,000 • 8 exposures stacked to reduce noise.

MSM 2-in-1 Star Tracker Review

"Head on Collision with the Milky Way" ~ a tracked and blended exposure, taken on a lonely road near Buhl, Idaho. The sky portion is a two-minute exposure, tracked with the MOVE-SHOOT-MOVE 2-in-1 Star Tracker. The highway was a separate, blended exposure taken during the morning twilight. The car headlights were one of three lucky occurrences that happened near 4:00 that morning!

MOVE-SHOOT-MOVE is a compact star tracker that also doubles as a time-lapse rotator. I have friends who have bought star trackers and have never used them to take a photo, because they were too complicated to set up! And these are intelligent people. The Move-Shoot-Move is the most compact and easy to set up star tracker I have ever used. From the time I placed it on my tripod to finished alignment was only about two minutes, and within a couple more minutes I was shooting tracked images of the stars. Now I discover it can do time-lapse movements as well! That will be my next outing—however this review will be mainly about its star tracking features.



The MSM Tracker/Rotator is only 3.875 x 3.125 x 1.375 inches (9.84 x 7.94 x 3.49 cm). Weight is only 1.01 pounds (450 g). It's simple 2-button design controls Northern and Southern Hemisphere rotations, full and 1/2 tracking speeds, and four choices of time-lapse movement speeds. Power is supplied by an internal lithium-ion battery that is non-interchangeable, but is rechargeable via a supplied USB cable. Although they claim over 5 hours of runtime, I was only able to get a little over of 2 hours of use during the colder winter months (before a blinking red light indicated the battery was getting low), which is quite typical of li-ion batteries under cold conditions. When I've need longer tracking (or rotator) time, I've plugged in a portable auxiliary USB power source (the MSM will operate while it is recharging or receiving auxiliary power). 

Limitations: The MSM has a maximum load capacity of 6.6 pounds (3 kg), which compares to the popular iOptron SkyTracker Pro and my first tracker, the Vixen Polarie Star Tracker. If you need a tracker that can carry heavier loads and has more available counter balance accessories, I'd recommend the Sky-Watcher Star Adventurer, with its 11 pound payload capacity—however, be prepared for a more intimidating set up (my first experience took me over half an hour).



Here's my personal set-up, using the MSM 2-in1 Tracker/Rotator. I used my own MeFoto ballhead, but MSM's basic "Starter Kit" comes with a similar ballhead (actually better quality than my MeFoto Q1) and a laser Star Pointer for $310.00 (current sale pricing is $259.00). Although you may already have a ballhead lying around like I did, I strongly recommend going with the "Starter Kit" option because these orders are shipped from a U.S. warehouse, and only take about 4 days to get to most continental U.S. locations. Other kit options ship directly from the factory in China and my first order took over two weeks to arrive to my Utah address.

My same set-up viewed from a different angle. The green laser Star Pointer (included with the "Starter Kit") attaches to the MSM unit via a nylon thumb screw and the laser slides into the laser holder, which is secured by another nylon thumb screw. The tripod ballhead is released and the MSM, with the attached laser, are then pointed at Polaris (the North Star), which properly aligns the system (often in less than 30 seconds)! The camera is then attached to the MSM's ballhead via its quick release and pointed towards the Milky Way or a star constellation. The whole process only takes a few minutes.



The green laser Star Pointer makes alignment a quick and uncomplicated process. I found the alignment accuracy to be very good when using any wide angle lens, and even accurate for a normal 50mm lens. My 85mm started to show slight star movement on exposures over 3 minutes, so I'd recommend MSM's optional Polar Scope ($79.98) when using telephoto lenses.

Dim laser beam problem: The Star Pointer comes with a rechargeable li-ion battery and USB charger. I found the brightness of the green laser beam diminished significantly on cold nights. However, by removing the li-ion battery and warming it in my hand or pocket for just a few minutes brought the brightness back to normal strength.

If you live in Australia, I'd suggest you order with the Polar Scope option (Basic Kit A), because laser pointers are not allowed in your country. In fact, anyone living in the Southern Hemisphere might want to use this option. If you travel a lot, you may wish to get both the Star Pointer and the Polar Scope (Basic Kit C).



Comparing Quality: Here's an enlargement from the top image, showing the Rho Ophiuchi cloud complex area. I'm comparing the same area exposed with the tracker off, using a 30-second exposure (click to enlarge for detail). Note how the longer, tracked exposure allows for lower ISO settings, reducing noise and improving detail. Even longer tracked exposures will allow one to stop down the aperture to also reduce lens aberrations. (This 24mm f/1.4 lens gets about a 65% reduction in chromatic and coma aberration when stopped down to f/2.8. At f/4.0, it would lose about 85% of its coma and chromatic problems.)



In this 200% enlargement comparison, you can see that even at 15 seconds, there is some star movement, although it probably wouldn't be too noticeable until one made a print larger than 16x20 inches. What is very noticeable, even in smaller prints, is the huge increase in the number of stars that tracking picks up, and the increase in tonal range (bit-depth) due to the lower ISO's and the light gathering power that a tracker allows your sensor to capture.

How does tracking compare with stacking? I often refer to stacking as the "poor man's answer to tracking." Quickly shooting about 7 to 15 exposures to stack later (with Starry Landscape Stacker or Sequator) will significantly reduce your digital noise, but it won't increase the detail (including the number of smaller stars you'll pick up) and tonal range nearly as much as tracking will.

Orion's Belt and the Orion Nebula ~ a 2 minute exposure without and with tracking (using an 85mm lens).

Pros & Cons: I love the MSM's simple, modular design and its ability to add accessories when needed. I use the laser Star Pointer for most of my tracked shots, and I rarely need the accuracy of the Polar Scope—but it's nice to have it when needed. Ever since I got this tracker, I've been shooting a lot more tracked shot, because it's much easier to set up than any tracker I've ever used. I can't wait wait to start using the time-lapse movement features! My only con is its 6.6 pounds limitation on load capacity, which has never been a limitation for the equipment I use, but might be for some who would want to use a big telephoto lens.

In Conclusion: I think Chris Cook, a MSM owner from Sydney, Australia summed it up best: "The biggest difference I’ve found is the colours which are brought out with longer exposures. A stack of 10 or more photos at 3200 or 6400 [ISO] at 10-15 secs [each] looks great; but, when compared to a single shot at 640 [ISO] for 150 secs, there is no comparison. The star colours are amazing and the nebula are much more noticeable."


Time-lapse Movement Feature: The MSM is a 2-in-1 product that also has four movement speeds to its rotator. This allows for several time-lapse options. MSM offers several tutorials on this, including YouTube videos.
