A:AnswerYes, but it's never a wise decision to trust your camera gear to a cheap tripod. I wouldn't trust this tripod with a $100 camera. When you consider how much money you spend on your camera and lens, the last thing you want to do is be cheap when it comes to the tripod that is going to support your gear. I would not buy this tripod for an 80D, not a chance.
A:AnswerYou can find adaptor screws, but I would NOT use it for anything larger or heavier than a camera, camcorder or phone.
Try something stronger and sturdier.
A:AnswerI think your telescope has a 1/4 20 thread to connect the base to it's included tripod. Unless you broke the original Celestron tripod, I would not replace it with this.
A:AnswerAs long as your camera has the screw hole on the bottom, the tripod has the piece with the screw that will go into it. This tripod has worked well with my video cameras (Canons) and DLSRs (Nikon) that are moderately heavy.
A:AnswerI have a Nikon D3200. The tripod has a standard threaded mount that attaches to the bottom of the camera. The mount then attaches to the tripod with a latching mechanism. So, you can easily take the camera on and off of the tripod. I believe that all Nikon cameras have the same threaded mount on the bottom of the camera. It seems that this threaded mounting is a universal for all cameras.
