Reprocess of M78, with 2.5 hours of data added

[michael.h.f.wilkinson]

I had some data lying around that I hadn't processed properly, due to issues with dust bunnies. I made some new flats, and that seems to have sorted the dust bunnies out,although there are still some issues with gradients. I added the data to a set of 2h 45 minutes I gathered earlier, and there is indeed some imrpovement, although I still  need far more (and better) data to be satisfied.

Stacked in APP, colour denoising in FITSwork, curves and crop in Gimp. All data acquired with my Meade SN6 6" F/5 Schmidt-Newton, and ASI183MC (non-cooled) camera. Next winter I will have a go with the ASI183MM-Pro, and acquire the colour at 2x2 binning.

That already looks pretty dam good to me!

Looking good Michael.  When I imaged it I found it to be a messy old thing with dark and reflection nebulosity thrown together with some Ha.

It is odd, has these strange dark blotches that make you feel your background has gradients caused by LP, and it is not very bright. I also had issues with the the fact that it is pretty low in the sky. Especially as Orion was moving to the west, you can see the subs deteriorating in quality as M78 gets lower in the sky. Better luck next winter, when hopefully I can travel to a dark site to image this properly
