Shot using a SBIG ST-2000XM thru a Meade LX200 10" f/6.3 telescope at approx. f/4.7. The luminance channel was 6 separate exposures of 5 minutes each averaged. Self guided by the SBIG ST-2000XM. Imager running -19.98 below ambient temperature which was about 35F. RGB/5:5:5 with a 1.6:.8:1 combine ratio. DDP & Unsharpened Mask applied. I tried not to blow out the core but still retain the detail in the arms.
