Dolphin Head (SH2-308)
The Dolphin Head nebula has been impossible to capture from my London home at 51 degrees north, as it barely peeks above the horizon. With my remote telescope at 31 degrees north in Texas this became an opportunity, although it was still pretty low down. My telescope needed lots of troubleshooting before I was able to finish, including a snapped cable.
Total exposure: 20h 35m
OIII 174 x 300, Ha 65 x 300
RGB for stars: R 40x20, G 40x20, B 40x20
