I want to get back into taking 35mm astrophotography and I looking for a low cost equatorial head or high quality barn-door type tracker. I will be using a Cannon SLR with up to a 300mm lens and a heavy Bogen tripod. What are my options? Are there any good but low cost equatorial heads? I have looked into the CG5 head but wasn't impressed with the quality and the CG8 is too expensive. My requirements are as follows: - Ability to align the equatorial head. - Ability to carry the weight of the 35mm camera plus 300mm telephoto lens. - Ability to RA track up to 45 minutes. - Ability to mount to a tripod.
