20" Mirror Test - part 2 small targets

One of my challenges since seeing Triton around Neptune in a 10" scope, was to image it. I didn't realise how easy this would be. It only took a few 4 - 10 second exposures on the 20" scope to easily capture Triton, which is 13.5 magnitude, and pinkish compared to Neptune's bluish. The separation is about 15 arc seconds, so there is either a tiny bit of coma or more likely inexact focusing.
