Technical Details:

Imaged from MYHY Observatory in the Philadelphia suburbs in 2003 — one of the first color images I ever attempted! Equipment included a 10″ OGS RC at f/9 with an SBIG ST10XME on a Paramount ME. LRGB with about 2 hours Lum (unbinned) and 30 minutes RGB/channel (binned 2×2). Processed with CCDsoft and Adobe PS in 2003 and reprocessed with some newer techniques in 2015.
