Description

The Bubble Nebula is an emission nebula. The "bubble" is created by the stellar wind from a massive hot young central star, The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.



First tri-color narrowband with these 36mm 3nm Chromas. Presented here in a modified SHO palette.

Also the first fully unguided  image with the  AP1100GTO CP4 mount using a PE curve and no-encoders.

Average sub Eccentricity was 0.45 which I was very happy with, the stacked image was 0.39.
