Apochromatic 43 mm Digiscoping Lens for ATX/STX

This apochromatic telephoto lens connects a DSLR or mirrorless camera with an APS-size sensor to Swarovski ATX and STX spotting-scope viewing modules. A DRX eyepiece adapter sleeve is included to complete the mechanical link between scope and camera. The 43 mm aperture transmits sharp, contrast-rich stills and video. The unit weighs 1.2 pound.

DRX Eyepiece Sleeve and Retaining Collar

The bundled DRX eyepiece adapter sleeve ensures precise alignment of the camera sensor with the scope's focal plane for optimal image quality. A retaining collar and eyecup are also supplied to secure the assembly and protect the optics during use. No T2 camera adapter or camera body is provided, so those must be sourced separately.

For APS-Sensor Owners Using ATX/STX Modules

Photographers who already own a compatible Swarovski ATX or STX spotting scope and an APS/DX-format camera can add digiscoping capability with this lens. Buyers needing full-frame sensor coverage or those without a T2 adapter for their specific camera mount should look elsewhere.

Questions about this item

Will the 43 mm apochromatic lens or retaining collar need periodic servicing?

The lens and retaining collar are fixed optical components with no moving parts; they require no scheduled maintenance beyond normal cleaning of the glass surfaces.

What limits continuous use when the adapter is paired with an ATX or STX scope all day?

The limiting factor is the attached spotting scope's own thermal behaviour and the camera sensor's heat buildup during extended video recording.

Does the 1.2 pound adapter add noticeable heat or fan noise to the rig during long sessions?

The adapter is completely passive — it generates no heat and has no fan, so it adds neither thermal load nor audible noise to the setup.
