When yesterday evening started out with full cloud, i decided that if the weather cleared I'd have a break from from my Centaurus A project and try a different subject. Well the weather did clear, and as I hadn't had a go at M16 since about this time last year when I first started imaging, I thought it was time to give it another shot - this time with my VC200L and the f6.4 focal reducer.
This is 33 x 5min dithered subs at ISO800 with a modded 400D. Processed with Pixinsight. I seem to have brought my tilt issue under control with a slight readjustment of the set screws on the Vixen direct-wide photo adapter, together with using a focus point between the centre and left corner, rather than focusing dead centre of the frame.

The second frame is my effort from last year for comparison (15x8min subs with the same camera and a GSO f4 newtonian), which was processed with DSS and Darktable (which is a linux version of Adobe Lightroom).
