Taken at the Spring 2017 Staunton River Star Party over the nights of March 23rd and March 24th.

Challenging field for a 70mm refractor but I used drizzle to try to help resolve the small galaxies better and not look as pixelated.

First night out with a new focuser and I can see there is some tilt - fortunately the focuser allows for adjustment.

Tight crop of inner region: CROPPED VERSION.
