Description

Had a particularly good night of seeing last night so went over to M15 and grabbed 300 x 15s of R/G/B data. Dithered frames in Pixinsight and then ran some aggressive deconvolution on the extracted L channel and then recombined the L back with the RGB. Overall I was pleased - there is still an artificial look to the image but for an 8 inch instrument sampling at 1 arcsec/pixel I think it has some good detail.
