Description

Here's a shot I've been sitting on for about...6 months. Stupid COVID, I had done pretty much all the subs for this, but got so busy with other stuff I completely forgot about finishing it, all I had to do was get new dark frames for calibration. So I put this edit together really quick yesterday, it's such an interesting feature with tons of dust and makes a very "artsy" SHO target.

Shot with an ASI183mm Pro on a William Optics GT81 with a Sirius EQ-G mount, gain 178 offset 11.
