M106 LRGB again!

[DaveS]

Feels like I've been working on this forever.

Last year I captured a load of LRGB data in Bin 1 which had a light leak in a lot of the subs. In the end I discarded all the duff subs and combined the rest into a Synthetic Luminance which got a DDP stretch as well as Richardson-Lucy deconvolution, Unsharp Mask, Denoise and slight Histogram Stretch.

This year I got 9 subs RGB in Bin 2 with G2v calibration, of which DSS stacked the best 8. these were combined into a RGB and layered with the Synthetic Luminance. I also got 5 hours H-alpha but in the end didn't use it as it caused some intractable alignment issues (No, I don't know why).

This is the result, saved as a JPEG.

C&C welcome, as well as suggestions as to how to proceed from here. I think I will try to get another 9 subs RGB, and *maybe* another 5 hours H-alpha.

 

Edit: It's worth having a look at the full size image, There are a lot of faint fuzzies that are worth tracking down.
