Hah! Thanks for that tip, I will check it out. I was thinking of designing and printing a 3D one, but if I can find one pre-made...:)
Even better!
On our family trip to Yellowstone for my 60th birthday (13 years ago), we stopped at various locations and were able to use spotting scopes. They are the greatest! A couple years after that trip, I did a lot of spotting scope research and finally bought a Kowa scope which I really like. You can buy adapters to mount your camera (without lens) or phone to the spotting scope. If you really want some great optical performance, a spotting scope can’t be beat.
