C-9, SH2-155, Cave Nebula

#1

Post by KathyNS »

Sh2-155, C-9, Cave Nebula. Considering it was shot under a full moon, it came out not too badly. Most of the data is Ha, so immune to moonlight.

Orion 200mm f/4 Newtonian
Atik 383L+

18x 600s Ha, 1x1
10x 300s L, 1x1
10ea 120s RGB, 2x2

total exposure time: 4h50m

Impressive for a full moon Kathy. The wispy purpleish nebulosity gives it an eerie look. Very nice job on processing the RGB with so much interference.
