Quote:I find the Skytracker holds itself very nicely with a 200mm lens. I use a Canon 70-200 f/4L and have managed ( test ) up to 4 minutes without star streaks.
Quote:I'm looking to buy a mount for astrophotography with a DSLR and lenses up to 200mm.So far these are the options I've found:AstrotracVixen PolarieiOptron SkytrackerThe Astrotrac seems to be the best, but it's out of my price range. I'm leaning towards buying the iOptron, since it's the least expensive with the included polar scope. From what I've read, the Vixen Polarie is nearly useless without buying the polar scope. Are there any options that I've missed?Also my tripod head has a 3/8" to 1/4" adapter stuck in it. I should have returned it when I first bought it. Does this mean I won't be able to use it with one of these mounts since they use a 3/8" screw?
