Description

A reprocess of my Bubble Nebula shot. I wanted to show the impressive star field more and to bring out more of the surrounding nebula. This was captured from my very light polluted front yard.

Taken with my DIY modded Sony Nex-5. Total exposure time only 53 minutes with 60 second subs.
