NGC2359 - Thor's Helmet (Narrowband, HOO)
NGC2359 is an emission nebula located 12,000 lightyears away in Canis Major. It's also known as Thor's Helmet, given its similarity in shape to the Norse god's famous helmet. The nebula is produced by a massive, hot Wolf-Rayet star emitting a stream of charged particles known as a stellar wind that's expanding outwards to produce an interstellar bubble.
This is the second target I imaged with my brand new FLT 132, so second light :-). Still trying to get acquainted with this new beast of a telescope, balance it properly on the AM5 mount and TC40 carbon fibre tripod. The two nights I managed to image, were partly cloudy and windy, so it was an added challenge to get good guiding. I imaged with the 1.0x FLAT68III flattener, so at the native 910mm focal length and a narrowband (3nm Ha and Oiii) Optolong L-Ultimate filter.
This was a total integration time of 5h45m. Preprocessed with PixInsight and post-processed with PixInsight and Affinity Photo 2.

Thanks for looking and clear skies.
