Sequator is a free Windows / PC software which can track stars on multiple images, align stars and stack them. According to Michael Ver Sprill, it is the first PC software he has found that favorably compares to Starry Landscape Stacker for the Mac!

“I typically use my iMac for editing stacked images and a program called Starry Landscape Stacker which really helps reduce noise and maintain sharpness. However it is for Apple computers only until I came across SEQUATOR. This program is very similar to SLS. The results were practically identical and this seems to be a great alternative for PC users,” says Mike.

Sequator vs. Fitswork: Ralf Rohner has done a nice job comparing Sequator with Fitswork, another popular Windows based star stacking program. He highly recommends Sequator to process an untracked image sequence. "On Windows, it is by far the easiest to use and fastest stacking software for nightscapes and produces very good results. Even beginners can immediately produce excellent results. There are no excuses anymore for noisy single shot nightsapes," says Ralf.

Ralf found Sequator “...really easy to use and it took me less than 5 minutes to produce the result, while my normal workflow in Fitswork takes about 3 hours to arrive at the same stage…The only point where I disagree Mike, is that for better sharpness and less no burned highlights, I recommend to use HDR instead of Auto Brightness.”
