Adapter Redleaf SOM-3 for mounting smartphones on spotting scopes, telescopes and microscopes

The Redleaf SOM-3 adapter enables secure attachment of smartphones to spotting scopes, telescopes and microscopes for digiscoping, astrophotography and microscopy imaging. It features an adjustable clamp and alignment mechanism that centers the phone camera over eyepieces and accommodates a range of phone sizes and eyepiece diameters. The adapter is designed to create stable optical alignment for photographing or recording through oculars in field, observatory or laboratory settings.

Advantages

The adapter provides a stable mechanical connection between a smartphone and optical instruments, reducing vignetting and misalignment. Its adjustable clamp fits various smartphone widths and the centering mechanism allows precise alignment with eyepieces to improve image quality. The construction is compact and portable, enabling quick setup and repeatable positioning for series documentation or time-lapse capture.

Suitable for

• Digiscoping with spotting scopes
• Amateur and mobile astrophotography through telescopes
• Microscopy imaging and documentation in educational or lab environments
• Field observation recording and sharing

Key specifications

• Adjustable smartphone clamp to accommodate a range of phone widths
• Eyepiece centering / alignment mechanism compatible with multiple eyepiece diameters
• Compact and lightweight construction for portable use
• Secure mechanical grip to minimise movement and vibration during capture
• Quick-release or adjustable mounting for fast setup and repeatable positioning

How to use

Attach the adapter to the eyepiece of the spotting scope, telescope or microscope according to the instrument’s eyepiece diameter, then tighten the alignment mechanism to hold it firmly in place. Place the smartphone in the clamp and adjust the phone position so the camera lens is centered over the eyepiece view; use the centering controls to eliminate vignetting and ensure a full field of view. Make fine adjustments while viewing the live image on the phone screen, then secure all clamps before capturing photos or videos.

Usage recommendations

For best results, ensure eyepiece and smartphone lenses are clean and free of dust, work on a stable surface or tripod to reduce movement, and perform fine alignment while using live preview on the phone. When using with telescopes for astrophotography, use short video capture to select sharp frames or use stacking software for improved detail. Verify compatibility of the adapter with your eyepiece diameter and phone thickness before use.
