19 60S Subs, hand picked and stacked in AIP4Win 2.2. Dark subtract done on the fly in Envisage, flat frame and bias calibration done in AIP4Win 2.2 for each individual LRGB channel. Calibrated channels aligned and joined in AIP4WIN 2.2 and enhanced using sky background fix followed by slight stretch. Final finishing in Photoshop (slight unsharp mask).

Previous image looked a bit small, so took the opportunity to image this at the prime focus whilst doing some other trials. Also increased the exposure to fill the DSI III histogram more efficiently.
