M82 and M81/M82 mosaic from Paris with my 8" f/4 Newtonian

[Dan_Paris]

Hi,

after M81 imaged earlier this month  I had three clear nights this week for M82, despite the nearly full moon. The first two nights were devoted to H-alpha (18 hours in total), with rather bad seeing. The t I did the LRGB (6 hours of L and 3*40 of RGB) with much better seeing (2" FWHM after stacking).

Here is first the mosaic with M81 (right-click for full resolution):

A crop on M82:

and on M81 (image already posted)

 

Thanks for looking and clear skies,

 

Dan

Very nice, although cant help but notice that your stars on the left side of the image are teal/green?

Thanks for noticing it, I actually did a stupid mistake : I forgot the red channel for the stars layer 😅  OP is corrected.
