Works well on vortex diamondback with iphone 13 - Novagrade Phone Adapter

This phone adapter works well on my Vortex Diamondback HD 20-60x85 Spotting Scope (Angled) with my iPhone 13 Pro. Once the adapter is tightened to the scope it is stable. After the initial set up you insert your phone in the spring loaded adapter clamps, place the adapter on the scope and tighten the compression ring around the scope's eyepiece and you're ready to go. The adapter can be adjusted for different phones or optics as needed, unlike the other digiscoping adapters I considered.
