been a while and got to grips with what i think is my personal best LRGB image, not perfect by any means but usually my LRGB stuff is pants,

around 61 x 3 minute subs of luminescence, 38 x 3 minute each of RGB all with flats some with bias none with darks, the stacking in deep sky stacker was a real trial and error, the only one which liked dark frames was the luminance channel, all the rest came out awful, the blue channel did not like darks or bias frames, i`m not sure it liked flat frames either as they did not get rid of the dust bunnies, really must clean my stuff, anyway without further ado, here it is, hope you like.
