Sh2-155 - The Cave nebula

Picture
​​The Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and is approximately 2400 light years from Earth.

​Details
M: Mesu 200

35x1800s OIII
35x1800s SII

​52hrs and 30 minutes total exposure time


It is interesting here to see the difference on a target that focal length can make....... The above is taken with a longer focal length scope at 1200mm compared to the image below that is taken at 330mm..... both of these images are using the same camera, so the big difference in scale is due to the telescope alone.
