Deep into the complex nebulosity in Cygnus with PN G091.6+01.8 as a bonus

[gorann]

This is a two-panel mosaic of a rather rarely image area in Cygnus, a bit north of NGC7000. It contains a nice mix of red Ha-emitting nebulosity, dark nebulae and blue reflection nebulae.

I imaged it over two recent nights with my dual-RASA8 rig with NBZ filter (Ha+Oiii) on one of the scopes and without filter on the other. I then essentially mixed the data 50:50, so this is a HaOiiiRGB image. Total integration time was about 36 hours. Given that it is a f/2 system and I gave it a decent integration time the image is quite deep and show more dust and colours than any image I have seen of this area.

While processing I noticed a small PN like structure. It is identified by the Astrobin platesolve as PK091+01.1 but it is registered as PN G091.6+01.8 in Simbad. Surprisingly I cannot find it on
https://planetarynebulae.net/. I have not been able to find any other images of it so I thought it could be worth posting a crop even if a RASA has really a too short focal length for imaging small PNs.

Another super image Goran, love the little PN and blue reflection nebulae.

Thanks a lot Dave! Those are my darlings too😉
