I did some 'clean up' of the blocking filter of my Canon 350d yesterday. This required the complete dis-assembly of the camera (again) to be able to remove and clean the filter. The flat frames I had been using were really bad (a lot of dust bunnies!). So this is my first attempt with the cleaned filter.
SW 254N, Atlas EQ-g, guided, 18 each 5 min. images. ISO 1600. Canon 350d modified, pre-processed in Nebulosity 3, post processed in Startools v1.2.
