Description

A long session from home (orange / red zone) now that I have a mount not needing much babysitting. 105 mm f/2.5 Nikon lens @ about f/3.2, ISO 200 to avoid saturating on the sky with 2 minute subs.

I want to try some deep wide images containing a whole lot of galaxies ... this was a pretty successful test, but it looks as though I'll have to do at least a long night at one of my darker locations if I want to get the kind of statistics I want!
