Hmm, no-where near the Swan then :

Magnitude: 6.00
Surface Brightness: 13.00
Description: !!!,B,eL,eiF,2 hooked
Omega nebula;Swan Nebula;many F outer loops;use filter
J2000 RA: 18h20m48.00s DE:-16°11'00.0"
Date RA: 18h21m11.02s DE:-16°10'47.8"
A mystery blue blob, not in my cdc catalog, and it shows motion over 30 mins? Is it a processing artefact after all....I'll check the raw FITS files....thoughts anyone - internal reflections?
OK 105,271 is a hot green pixel - odd thing is that the dark frames did not get rid of this one...but the others are gone...
