Description

I captured this same target a few months ago, but wanted to revisit it and capture a lot more data to try and bring out the very faint Soap Bubble Nebula.

This is the most data I've captured on a single target with the RASA 11" - about 11 hours, captured over 3 nights, with most of that on the OIII filter for the Soap Bubble.
