Finally I have something like First Light with the ODK12. This is just 6 x 600 sec subs Luminance with the Moravian G3 16200 and Chroma filters. Sigma Add stacking in AstroArt 7 followed by a slight crop to get rid of dither edges, Gradient Reduction (As the moon was starting to interfere), DDP and Unsharp Mask.
Calibration was with Darks and Flats only as I had neglected to do Dark Flats *slapped wrist*.
Reduced 50% for upload and JPEG. Yes it's a bit noisy, and I think I may have focus issues.
C&C welcome as usual.
M33 captured over 4 nights, 16hrs of data using 300sec subs, darks from library, mixed flats for an average and bias frames. Camera: Canon 600D. Everything put into Deep Sky Stacker and the resulting image processed in PS.
I used a video made by Scott Rosen on processing to help me process and I learnt some really powerful techniques to use in PS. I think this is my best processed image to date, so I feel happy I have made some progress. Looking forward to reprocessing my old data armed with the new knowledge 🙂.

This is my version of the Rosette nebula using the Hubble and taken with the ASI071 OSC camera. Telescope was a C925 EdgeHD with Hyperstar lens.
Exposure time: 4hr 50 min in total at unity gain
2hr 00 min (24 x 5 min) Ha
1h 15 min (55 x 5 min) OIII
1hr 35 min (19 x 5 min) SII
This setup is awesome. A few years ago such an image just could’ve been taken with a monochrome ccd.
