I have an old tasco 99vr 60 x 300mm scope to use a a guide scope modified to accept my agent v5 web cam. I achieved daytime focus to about 500m (the furthest object I could find) and I still had what I thought was sufficient front and rear focus for stars- the intent was to use this combo as a guide scope. When I tested it last night I couldn't focus/find a star on my screen at all. Do I need to remove the IR filter from the front of my CCD chip to get stars or does the old tasco just not have enough light gathering power? Ive read about 50mm conversions for guide scopes so I should get enough light??
