Bubble & Lobster Nebula (NGC7635 & SH2-157)
Bubble & Lobster Nebula (NGC7635 & SH2-157)
This was 3 nights of terrible photos, but decided to process it anyway in Sii, Ha, Oiii hubble palette. The lobster claw in one corner and the bubble nebula (ngc7635) in one corner make for a nice target in one frame. The bubble lies in a stellar nursery where there is enough interstellar dense dust to start forming molecules… In this case mostly Hydrogen.
