Description

I did a belt mod and hypertune on my atlas and wanted to see how it would perform. I've also spent a significant amount of time to truly understand Collimation. To test all of this out, I revisted a target that I had previously imaged with a NEWT. This time 183MM-Pro at 800mm FL.

I have to say, the 183MM-Pro pairs very well with fast, large aperture scopes. The pixel scale is very comfortable at .62" with my 8in Newt and the details captured are excellent. It's really made for fast OTA's that let you keep the gain down. For this I used 3min exposures at Gain 178.

C&C Welcome.
