Eyepiece-Mount Digiscoping Adapter

Product size: 122 × 78 × 43.5 mm. Net weight: 103 g. Housing material: PA + GF — selected for stiffness-to-weight ratio and long-term creep resistance. Phone width capacity: 66–95 mm; depth limit: 19 mm. Eyepiece compatibility: outer diameter 23–50 mm — covers 98% of consumer and prosumer optical devices sold in the EU, including Kowa, Celestron, Vortex, Nikon, Leica and Zeiss models. Includes full EVA padding set (1× circular, 3× stepped) and English manual. The core functionality revolves around three integrated systems: (1) A spring-assisted quick-clamp for phones, (2) A linear slide rail enabling fine focus adjustment within ±2 mm range, and (3) A dual-axis 360° rotation joint with locking screw to fix orientation. All adjustments are tactile and repeatable — no need for recalibration between sessions. The curved contact surface matches typical eyepiece curvature, maximising surface contact and minimising point-loading risks. Used extensively by UK wildlife photographers and environmental surveyors — its compact footprint integrates cleanly with tripod-mounted spotting scopes and avoids interference with diopter rings or focus knobs. Also validated for classroom microscope imaging where consistent sensor-to-eyepiece distance is required across student groups.
