Description

Testing out the tracking ability of SkyWatcher Star Adventurer and the Optolong L-Pro 77mm filter in the backyard last night. It was cold. Humidity about 40%. Tried to shoot more lights but the clouds moved in. Overall I like what it came out.

Overall I am happy! Single shot color DSLR with only a DSLR lens. Two of my neighbors' backyard lights are on and above my fence. But they didn't impact the SNR that much. Next target is M31 from the backyard!

First time using Astro Pixel Processor as the pre-processing tool. Simple & straightforward, very impressive.
