Description

There is a lot going on in this a mix of Samyang 135 and RASA 8 data (all with IDAS NBZ filter so mainly Ha and Oiii) that I collected before this area fell below my horizon. The big Oiii emitting SNR to the left is G179.0+2.6. The small red PN inside M37 star cluster is IPHASX J055226.2+323724. Sh2-241 is a relatively often imaged Ha-object. However, what strikes me as odd are the two large Ha-emitting nebulae below Sh2-241. They are apparently not occurring in any catalogues. @Wim van Berlo helped me search Simbad and nothing turns up that could be designations for these large patches of nebulosity. Yes, they are large (the left one has a diameter over 1°) but quite a bit more faint than Sh2-241.

Not sure if they could be called "New Discoveries", or what the criteria are for such, but they are at least previously uncatalogued objects as far as I and Wim can tell.
