I think its kind of slipped under the radar for a lot of people but Frank over at SetiAstro has just updated Cosmic Clarity sharpening section with a correction option. I was curious if it really was serious competition to BlurX. The images were treated the same with the only difference being the sharpening/correction software used. Here’s the results:

📷 comp-2.jpgcomp-2.jpgYou can come to your own conclusions with your own data but to my eye, they are very close. At extreme zoom they both hallucinate differently. Both are delivering very usable results. More testing would be needed to really know which is closer to being truthful.

BlurX was used at default values. CC was adjusted to match, approximately 15% over default setting.

I love PI, it’s still the best overall workspace and has some great tools but I have to say that IMO, BlurX isn’t the only game in town anymore.

…and the nice part of Frank’s work is that you can still use CC from PI itself to see which one works best for you.

I agree. I don’t know why RC Astro locked them selves into PI so strongly. You could always get noiseX and starX for photoshop and Affinity but never BlurX.

Hey thanks! I have SAS but don't open it as much as I used to since getting PI so I appreciate the info.

I’m finding that I still bounce around a bit. I’ll grade and cull in SASpro, stack in Siril because of its speed then off to PI for the heavy lifting, then out to Affinity for final adjustments. It’s really great to be able to use the absolute best tools (or at least the ones I like best) for the different parts of the job.
