I decided to see what difference I could get by setting up an imaging run with double the 20 minute exposure so I set up a 40 minute imaging run. 600 seconds each L,R,G,B
these are the "raw" images straight from the scope, a jpg. I have the fits images but haven't processed them yet and I didn't touch these files just uploaded them directly. The 40 minute has more depth.
These were shot on the 16" f/3.5 Dreamscope Astrograph
20 minute exposure
40 minute exposure
I might not always be right but I am never wrong, once I thought I was wrong, but I was mistaken...
