| Notes: Luminance Images obtained with unbinned pixels, all colour exposures obtained at 2x2 binning, RGB ratio of 1:1:1.6 set and colour components normalised in Maxim CCD. Processed in Maxim CCD and Photoshop 5.5 Colour balance was difficult with this image due to a problem with contamination in the coating of the Green and Blue dichroic filters (SBIG replaced these free of charge and with an amazingly quick turnaround - typical of the company's great customer service) |
