According to OPT salespeople the answer is yes. What I don't know is if the wedge is better. than a gear head.
IMO, The Wedge is way better. I have tested the Astrotrac scope alignment using a RRS BH-55 ball-head, a Gitzo GH2720FQR Gear Head (better than the Manfrotto 410) and the Astrotrac Wedge. There is really no comparison here...
With a gear head or ball head, you get flexure. Meaning, when aiming Polaris to the etched mark, you have to aim it above the spot because once you lock it, the star will move down. After numerous attempts, you can get it reasonably aligned. For this task, a gear head is easier than a ball head but the Wedge is perfect because the movements are fine and precise. Once you align Polaris in the correct mark, you are done!
The 2-pound Wedge is also very stable supporting 15 times its own weight. (Over 30 pounds)
If shooting with a wide-angle lens, they will all work but if you intend to go beyond 300-400mm, alignment precision is a must. I will also get an auto-guiding device for the next new moon.
I'm very close to mod my Canon 6D replacing its IR filter with one transparent, increasing sensitivity of hydrogen-alpha.
As far as I know, it should not mess up the camera for normal shooting as long as you use custom white balance. (which I do anyways).
Talk me out of it. Please.
