I recently took a single test sub of the eagle nebula using my new un-cooled ZWO ASI 174MM and it got me thinking... how would it compare to my DSLR on the same target under similar conditions?
The image on the left is a single 3.5min exposure, ISO1600, on an un-modded Canon 600D DSLR. The image on the right is a single 60sec exposure (using the default settings in Firecapture) with the ZWO ASI 174MM. Sorry I don't have the actual settings, it was literally my first night with the camera.
Chalk and cheese in my opinion.
I think it might be time to start saving for a new imaging camera
The scope is an 8" SCT, approx f/7. I also took a 600sec exposure at ISO800 on the DSLR, however the end result wasn't that much better. I'll upload that image separately.
Cheers, Evan
