I dont have the iphone adapter, but it's available:

This scope works great for seeing bullet holes in targets from 300+ yards away, even with my old eyes. The video cameras solve the same problem, but they put electronics downrange. I teach & coach, so I try not to put anything of value downrange. Also, I can put this in a backpack and take it to the field for glassing/photographing wildlife.
I also have their 5" version:

which is easier to carry and works great at 100+ yards.
These scopes work for astronomy too, and you can screw on a camera back and have a very long lens. The 5" gives you a 1250 mm lens with a 127mm objective. The 8" gives you a 2032 mm lens with a 203.2 objective. The big objective pulls in a lot of light, so you can see into the shadows better. When there's plenty of light, you can add a doubler at the back that doubles the magnification at the expense of half the brightness.
As these devices go, Celestron makes good products that are not nearly as expensive as their competition. Imagine glassing from an overwatch position, and being able to zoom way in to really see what you're looking at. In bright light, they can give you up to 580X and 350X respectively. For maximum light-gathering, in the dark, you'd run them at 29X and 18X respectively.
I've never understood the way some long-range shooters settle for optics that don't let them clearly see their target. Any mechanism that helps me clearly see my target becomes increasingly valuable as I get older.
