The Cave Nebula Sh2-155 and neighbouring Sh2-154

[gorann]

The Cave Nbula (Sh2-155) is well known but its slightly less spectacular neighbour in the Sharpess catalogue - Sh2-154 is not that often imaged. Clearly the whole area is full of Ha emitting dust as well as dark nebulosity (so several of the entres in Lynds' dark nebula catalogue) and then that nice blue reflection nebula VdB155.

Imaged during quite a bit of moonlight so the IDAS NBZ filter did a good job again.

So, caught 12 March 2022 with the dual-RASA8 rig with ASI2600MC and IDAS NBZ dual-band filter (Ha+Oiii). 76 x 5 min = 6 h 20 min (gain 100, offset 30, -15°C). Processed in PI and PS.

Comments most welcome

Cheers, Göran
