Image taken with a Coronado PST, 2x Barlow and Canon 1100D on an EQ5 Pro mount
Images shot in RAW with the camera set to mono to assist with focusing. Images then cropped and tweaked in Lightroom and exported as TIFFs

False colour was then added and the 2 images merged using a layer mask in Photoshop CS2, then final tweaks made in Lightroom and Focus Magic
Sketch was done with coloured pastel pencils on black paper then photographed
