I was wondering if anyone can give their opinion and options for a reducer for the above scope. I have the Celestron "dedicated" .7 reducer but would like to find something higher quality. I am noticing CA around brighter stars in my images. What is out there that would fit my application and desire for better performance?

 

Attached is the latest pic of the Needle Galaxy and as you can see I get a bit of red and blue that seems to be angled directionally to the center of the image.

You have fewer artifacts than I did with my Edge 8 and Celestron 0.7x reducer. I’m curious about what alternatives you find.

I’m curious as well. What about the Lepus Telecompressors? https://optecinc.com...lepus/index.htm

I wonder how they work with an APS-C sized sensor...

(Nice pic btw!)
