Some people have asked me about chromatic aberration on the Sharpstar 94EDPH. I really don't see any CA to be worried about but I figured I'd post an image of a bright star for people to decide for themselves. 

 

This is a 4 second exposure at ISO3200 on a Sony a7II taken quickly without any calibration frames. I can do more testing if there is any interest in this. I'm not a level 70 optical nerd so for me the results are satisfactory, but feel free to let me know what I can do to test this more thoroughly.

Hi, I personally haven’t noticed it yet. I have a small sensor though ASI183 Mono.

 

I think colors align very well in my RGB filters.
