Deep dive on the Orion Nebula.

[Magnum]

Deep dive on the Orion Nebula last night.

This is 2hrs of data in Hydrogen Alpha comprising of 12 X 10 min + 30 x 30 secs to recover the core, with my Atik383 CCD & 102mm triplet at f5.5.

I have stretched it to the noise limit to get as deep as possible, maybe at the expense of smoothness but I quite like it. Guided, captured, stacked and stretched in MaximDL, processed in Photoshop, No Darks or Flats, Only Bias .

Not sure why but I notice when I post on here the dark parts of the image get very grainy, doesn't happen on FB which is opposite to what I would expect. oh well
