The Cave Nebula

[Andy Elliott]

Taken in September and about 10 hours exposure using the ASI2600MC and Esprit 100ED. I found this target a bit of a challenge in processing, I think I have finally got it how I want it.

The "Cave Nebula", in the centre of this image, is a popular name for Sh2-155, an emission nebula in the constellation Cepheus. It appears cave-like due to a dark, hollowed-out area surrounded by a bright, ionized gas rim, which is an active star-forming region.

The blue area of nebulosity to the upper left of the cave is the reflection nebula vdb155.

Thanks for looking

Awesome Andy! This is really sweet!

The Cave nebula is one of the hardest ones to capture in my book. It's way fainter then it seems. I have captured it but was not happy at all with it, I probably need to go after it again.
