NGC 4725 with companions NGC 4747 and 4712
Photo description / processing
This photo is from the guide scope. After all, a monochrome camera gathers color better than a color one.
It was shot in parallel, but nearly two hours of data had to be discarded due to tracking shifts and meridian flips.
Stacked with drizzle—2x.
