ASTRO: NGC 2282
NGC 2282/IC 2172 is a reflection nebula with an embedded star cluster
seen mostly in infrared light. Actually SIMBAD classifies it as a reflection nebula, NED as a star cluster under the NGC 2282 name and an HII region under the entry BSF 54 (Blitz+Fich+Stark HII regions). NED says IC 2172 doesn't exist. The NGC project lists it as a reflection nebula under both the IC and NGC numbers. It is located on Monoceros and thought to be about 5500 light-years distant. The cluster contains about 100 stars, a few of which are pre-main-sequence stars. It is thought to be about 5 to 10 million years old. You can read more about this object at http://articles.adsabs.harvard.edu/f...J....113.1788H . Like much of my imaging for 2012 and 2013 this one was severely damaged by clouds and poor seeing. The color data was especially thin. It is equal to only about 2 minutes of normal color data per channel rather than my normal 20 thanks to the clouds. I tried several times for better data but was thwarted each time. For that reason much of the emission features around one of the field stars was lost. It had some interesting wings that didn't survive the clouds. I'll try again in 2014 if the weather ever improves (still rotten as I type this). Still this is a rarely imaged nebula that should get a lot more attention than it is given so am putting this out hoping those with better skies will give it a try. 14" LX200R @ f/10, L=4x10' (one very poor) RGB=2x10' (all very poor), STL-11000XM, Paramount ME Rick -- Prefix is correct.

ASTRO: NGC 2282
Rick,
that nebula looks quite mysterious. Went straight on my list, even if it is almost too low for me. And I'll need all clear skies at that time of the year for NGC 2336 :-) Stefan "Rick Johnson" schrieb im Newsbeitrag .com...
