Sky Rover Optics S&M Adapter V2 for SRBC APO (Sky Rover Optics, SKU: 26815) is a dedicated adapter allowing smartphone photography through SRBC APO binoculars, also known as the Banner Cloud APO series. The adapter replaces the eyecup of one eyepiece and connects the binoculars to a suitable smartphone case or holder through threaded interfaces. This solution provides more stable and precise alignment of the camera lens with the optical axis of the eyepiece than typical clamp-style holders.
