Hi all
I finally got to try my new Hutech IDAS uv/ir filter in Bert's 300mm F2.8 flourite lens, along with the Baader UHCS filter.
Here's the result. The filter uv/ir definately cuts down starbloat caused by excess infra red light thats picked up by the modified 350D camera.
Both shots are 3x 10 mins ISO 200, f2.8
They are of Eta carina Nebula and NGC 3572 and environs. Taken last night (between clouds).
