Digiscoping?

I saw LAV’s video on the 2000m shot and noticed one of the guys was using what I think is a Galaxy Note attached to a spotting scope.

It’s called digiscoping in general and is often done for bird watching, allowing someone with a small point and shoot or phone to use a spotting scope as a zoom lens.

Does anyone do this? Does anyone have a suggestion on what mount to use for a smartphone to connect to a spotting scope?

I have a Galaxy S6 (16 megapixel camera, great quality) and a Bushnell Elite 15-45x spotting scope, but I’d prefer a more universal mount in case I upgrade scopes or something.

As far as universal mounts, this is the best I’ve found so far:

And as far as specific phone to universal mount, this seems reasonable too, although I’d prefer not to remove my phone case:

I’d also prefer not to spend $300-$400 on what the guy in the video was using:
