ok, most likely you will need to take the plate that is on top of the tripod and thread it into the Black bar at the bottom of the telescope. However... If the black bar (Called a Vixen Rail) does not have threads you might have to purchase a third party rail like this one on amazon
Yeah, my camera only has the singular tripod hole. Would something like this work? I'm from Canada so the one you had linked costs quite a bit to ship. Also, for the one I linked, is it worth buying a separate set of screws?
If you've got a 3D printer and a 1/4"-20 bolt

Will all let that work. I've used 2 of those 3, actually and they both work fairly well. I like the short one for things like a 50mm, and a long one for bigger lenses since you can make a ring for the lens and attach it.
