About six years ago I built a permanent DOME and fitted my scope with a 'cookbook' camera. The housing was machined out of solid aluminium which allowed a much better flange type seal, and the two inch barrel was threaded internally to accept a Pentax camera lens. They are then processed using AstroArt, Fits Image, Quantum Image or Super Fix then combined into color with Photo Styler. The following images are dithered to 256 colors so that all may enjoy them. Using a light meter, I exposed the filters to sunlight and all forms of artificial lights and found the three shades that gave the closest readings to each other.
All exposures are equal.
