The Hawke Digi-Scope Adaptor Endurance 68/85mm (Model 64021) is a precision-machined, all-metal digiscoping extension tube designed to connect DSLR and mirrorless camera bodies directly to spotting scope eyepieces. Engineered for compatibility with Hawke Endurance ED 68mm (16–48×68) and Hawke Endurance ED 85mm (20–60×85) spotting scopes, this adapter secures over the eyepiece thread to enable direct ultra-telephoto optical capture. By integrating a standard T2-mount thread interface, the passive mechanical tube eliminates the alignment errors and light leakage associated with handheld camera setups.

Key Features

• All-Metal Sleeve Construction: Provides a rigid optical barrel to support interchangeable-lens camera bodies without flexing.
• Adjustable Focal Extension: Features a variable extension height from 70 mm retracted to 82 mm extended to optimise camera sensor focal-plane alignment.
• Observation Window: Includes a 33 mm window cutout along the barrel for visual confirmation of eyepiece magnification settings.
• Dedicated Optical Direct-Mount: Interfaces natively with 53 mm inside diameter eyepiece assemblies and connects to camera-specific T2 ring adapters.
• Passive Mechanical Design: Requires no batteries or electrical power (0V), ensuring full functionality in any field environment.

Who is the Hawke Digi-Scope Adaptor Endurance 68/85mm for?

• Long-Range Target Shooters — Provides an adjustable 70 mm to 82 mm extension tube that secures a DSLR camera to an Endurance ED spotting scope, delivering rigid sensor alignment to capture high-magnification impact confirmation downrange at distances beyond 1,000 metres.
• Wildlife Observers — Integrates a 53 mm inside diameter mount with a 33 mm viewing window directly over the spotting scope eyepiece, allowing users to verify optical magnification settings while capturing high-resolution telephoto digiscoping imagery.

Less suitable for: Spotting scopes with smaller ocular housings (incompatible with 50 mm, 56 mm, and 65 mm Nature-Trek models), mobile smartphone photography, or mobile setups without a heavy-duty tripod; users requiring lightweight, packable setups or smartphone compatibility should select a universal clamp-on smartphone adapter.
