This little fellow was a difficult target for a moonlit night combined with poor seeing.
But Gotthard and Gary somehow got me hooked on this tiny but spectacular object.

It's obvious that this one needs pretty good conditions coupled with excellent PP skills (neither of which I have, to be honest).

Maybe I can encourage some people with longer focal lengths to give it a try. I'm sure it could work well as it's not as dim as you might think with mag 16, which is doable with today's cameras and techniques.
