The Fish Hook Nebula (MW-5) - IFN in Camelopardalis/Lynx

[gorann]

The last nights my hunt for Integrates Flux Nebulosity (IFN) has taken me to Mandel-Wilson 5 in Camelopardalis/Lynx. They named this structure The Fish Hook Nebula and I think I can see why. They classified it as faint but I found a least parts of it to be a bit brighter than most IFN. There is also quite a bit of red nebulosity in the image. Not sure if it is Ha emitting nebulosity of just IFN reflecting red, as some IFN / Galactic cirrus is apparently doing (see http://www.deepskycolors.com/archive/2017/01/01/Clouds-Of-Andromeda.html)

The second image shows an annotated image made in PI. Lots of small PGC galaxies but no fancy NGC or IC objects.

Captured during two nights 5-7 April using a RASA 8 and ASI2600MC (no filter, gain 100) on an iOptroc CEM70. 88 x 5 min, so 7.3 hours. SQM 21.3 - 21.6. Processed in PI and PS.

Thanks a lot Mark, glad you like it!

You're going to have to name your Rasa the IFN Hunter. That's some very feint stuff you're getting in very short integration times. Nicely done.
