The Medulla Nebula Supernova Remnant. Credit: Kimberly Sibbald

The Medulla nebula, also called Abell 85, LBN 576 and CTB-1, is a supernova remnant. CTB-1 is the expanding gas shell that was left when a massive star toward the constellation of Cassiopeia exploded about 10,000 years ago. This deep sky object it's pretty faint and needs some deep integrations to show some detail. I struggled to get as much data as I could with my dual Takahashi FSQ setup during several full moon January 2022 nights. For the nebula structure I used a 3nm Ha filter in front of my ASI2600M and FSQ106 EDX4. On the other side, the FSQ85 was gathering lots of data in [OIII] with the smaller ASI294MM sensor. RGB images were also captured to create the starfield image in natural color.

Are the colors in the visible spectrum, or enhanced?

I vaguely remember reading that they add color to help you see the form better? But I don't really know anything else about it.
