40hrs on The Little Rosette Nebula (SH2-284)

SH2-284 The Little Rosette

Lots of gorgeous structure with beautiful blue from OIII making a nice backdrop for various columns and dust lanes.  There are a number of unusual objects surrounding the area as well.  In my annotated version I highlighted Carbon stars, Peculiar Stars, Bubbles, and HII regions.  There is also a very strong SII red area directly below Bubble E79 that does not show up on any Simbad catalog and since it is most strongly in SII it may be a new structure!  There is also NGC2282 with its unusual dart structure that is unnamed as well.  The main bulb of SH2-284 is ionized by the bright young stars that form the cluster Dolidze 25.

Isn't SH2-170 the little Rosetta? 

Aside from that nice image well done. 

Above is my image of what I thought was the little Rosetta.

Thanks!

I saw the name on sharplesscatalog.com and went with it.  There is no well known name for this region, so maybe we come up with a better one!  I am at a loss for what wordly object it looks like to try and name it though.

Interesting find.  The JWST imaged this with NIRCAM

The title for the observation: Initial mass function in the lowest metallicity protocluster in the Galaxy.

 

I guess SH2-284 holds the record in the low metallicity protocluster category

Very impressive. Certainly no shortage of colour. 😉

I took the data and zoomed in from my image in a video if anyone is curious!
