Cassiopeia nebulae: from Bubble and Lobster Claw to the Cave

[gorann]

This is a two-panel mosaic from three recent nights taken with the RASA 8 and ASI2600MC (79 x 5 min so 6.6 hours). The moon was up and just about full so I used the IDAS NBX filter, making this is a Ha and Oiii image. I enhanced the details of the main nebulae with a bit of Esprit luminosity data that I had from last season. I agree with @ollypenrice that this should be within out artistic freedom.

All well known nebulae in Cassiopeia but not that often seen together. I like the band of dark nebulosity cutting through the image.

If you want to know what is in there I include the plate solved low resolution image generated by Astrobin.

I really enjoy this type of image. It gives a great perspective to several objects usually seen close up and alone and puts them all into context. Fantastic image.

Thanks a lot! Yes, I also like to see how these things relate to each other. I usually also see them as single objects. Surfing on Aladin sky atlas gives me a lot of aha-moments about iconic nebula actually being neighbours.

Yes, I have read somewhere that some of our individual DSO targets are not only neighbours but are actually part of the same complex or entity. I find this fascinating when we consider the sizes of many of these objects - even individually I find it difficult to visualize their enormous size. These scales are just so far removed from out experience.

Just boosted the colours a bit especially the blue, so the original post is edited. Thought is was a bit too Ha dominated.
