M13 Reprocess

[DaveS]

After seeing @Rodd's superb images I had another look at my data from earlier this year with the ODK rig. These were captured with G2v calibration (First order only) 600 sec Red and Green, 1050 sec Blue. Sigma stacked in AstroArt 8 then DDP and Richardson-Lucy deconvolution. Gradient Reductions, and LRGB synthesis after coregistering the individual RGB channels to the Luminance. Some rather odd cores in the brighter stars, probably from the R-L deconvolution bringing out DDP artifacts. I applied a selective colour attenuation to remove a bit of green and a saturation boost.

I may put the QHY 268M on the ODK to take short subs, perhaps that will keep colour in the brighter stars.
