Love it, works great on galaxies, ZWO ASI585MC fits perfectly. Color calibrate in seconds.

Great for the Celestron Origin
Got rid of a lot of red noise compared to the stock clear filter that came with my Origin imager. Helps with star bloat as well. Approximately the same number of frames in 2 examples. Not sure if it will come out well posted here, but the bottom is the Optolong and there is much less noise in those.

Reduce stars
This filter aided in reducing star and eliminate star bloating which is good since bright star can cause that which ruins the image
