Re: (IAAC) Obj: NGC 2244 - Inst: 200mm Newtonian F5

Thanks for that info Paul, I had realised from using Skymap that it was a complex bit of the sky!! I asked a few questions and although I got a good answer (the neb I think is 2237) I decided in the end to go with the designation the program used which I think is based on the  new NGC/IC Cat.
 I was uncertain as to whether it was an Emission or  Relection Nebula and in this instance decided to have a guess at the object classification as a guide which is II 3 r n:b I must admit to a certain ammount of laziness here in not checking correctly the code and assuming tht the r n stood for Reflection Neb!! 
But for certain it's an interesting and very complicated area and well worth a visit, I would imagine it must look quite incredible through a 12 inch or larger!!.
Kim.

Kim,

The Rosette Nebula itself is actually several NGC numbers (including NGC 2237,
2238, 2239 and 2246), and is a large EMISSION nebula located 3000-5000
light-years away. The stellar winds from the open cluster of stars known as NGC
2244 has cleared a hole in the nebula's center.

Your skills: Intermediate (some years)
Date/time of observation: 7 April 2002
Location of site: Sutton, West Wales (Lat 51 48 N, Elev 05 03 W)
Site classification: Rural
Sky darkness: 8 <1-10 Scale (10 best)>
Seeing: 5 <1-10 Seeing Scale (10 best)>
Moon presence: None - moon not in sky
Instrument: 200mm Newtonian F5
Magnification: 32X 100X  200X
Filter(s): OIII H-Beta
Object(s): NGC 2244
Category: Reflection nebula.
Class: II 3 r n:b
Constellation: Mon
Data: mag 4.8  size 24.0'
Position: RA 06:31  DEC +04:57
Description:
The Rossette Nebula, the central group of bright stars that seem to light this
photographically impressive nebula are very close and bright, the nebula itself
is bright enough for some structural details to be seen, mainly the darker area
around the cluster itself, OIII Filter seemed to improve the view a little but
H-Beta did not.
