NGC2237, The Rosette Nebula

[spacettf]

The Rosette nebula in HST palette by Sara Wager Via Flickr: The Rosette Nebula (also known as Caldwell 49) is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The cluster and nebula lie at a distance of some 5,000 light-years from Earth and measure roughly 50 light years in diameter. The radiation from the young stars excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 solar masses. This is taken with the dual Tak imaging system. This is the first time I've managed a proper 3 channel image of the Rosette. It was taken using the new Eagle S from PrimaLuceLab. Details: M: Mesu 200 T: Tak FSQ85 0.73x C: QSI683 and Moravian G2-8300 with Astrodon 3nm Ha, OIII and SII filters 30x1800s Ha 25x1800s OIII 25x1800s SII Totalling 40 hours total exposure

The Rosette Nebula is a large spherical H II region that looks like a rose and is located in the constellation of Monoceros with a open cluster NGC 2244 within in that has been formed from the nebula, their intense radiation blasting away the gas surrounding them. It is some 5,000 light years away and is approximately 130 light years across. This was imaged in Singapore with a Sony A7ii with a 70mm refractor. #rosettenebula #ngc2244 #cadwell49 #cadwell50 #ngc2237 #ngc2238 #ngc2239 #ngc2246 #ロセット星雲 #星雲 #天体写真 #天体観測 #nebulae #astrophotography #sonya7ii #alphacreatesstarscapes #alphacreates #blackandwhitephotography (at Singapore) https://www.instagram.com/p/Bs2AHwIFlhk/?utm_source=ig_tumblr_share&igshid=1xvc5dx2qvw8t

An artistic impression of NGC2237 (The Rosette nebula) by Sara Wager Via Flickr: An interesting title you may think and you may wonder why I have written artistic impression........ Firstly let me say that the raw data for this 'experiment' is all mine and has been recently acquired. There is nothing new there. What I have then done is considered the processing and have coined a term 'Monochrome channel mapping'. What this means is that this image has been 'created' using ONLY Ha data, there is nothing more in there. This is an experimentation processing technique that will horrify some and perhaps please others that this can be obtained by only having to acquire Ha data - In fact lets not be so prescriptive, the same could be done with any single filter data if the signal was sufficient. So I hope that you enjoy this experiment and the debate that it may bring within yourself. I hope that I won't get burnt at the stake for heresy........ Details M: Avalon Linear Fast reverse T: Takahashi FSQ85 0.73x C: QSI683 ws-g with Astrodon 3nm Ha filter 39x900s in Ha totalling 9h45m of exposure.
