Scope/DSLR coupler

A mechanical coupler to connect a DSLR camera to a spotting scope (digiscoping). Essentially a cylinder with three internal diameters.

Scope is Olivon 65mm; camera is Canon 350D. Easily modified to suit other scopes and cameras. T2 adapter purchased online.

The camera lens has to be replaced with the T2 adapter (machined aluminium). One end of the coupler attaches to the scope eyepiece (a tight interference fit) and the scope can be used normally. When you wish to take a photo you attach the camera to the coupler via the T2 adapter (a snug sliding fit).

Simple object to print. The best internal diameters and lengths need to be determined by printing test objects.

Works easily but with challenges in two areas - mechanical and optical.

Mechanically: the weight of the camera drags the scope eyepiece down. Extreme tightening of the tripod tilt mechanism is not a good solution. Perhaps a weight on far end of scope would work, but then you have another piece of kit to cart ar
