New AstroMechanics ASCOM Canon Lens Controller Specially Designed for ZWO ASI6200MM with Filter Wheel Cameras

We are pleased to announce FLO has the UK exclusive for this innovative new product which enables you to natively control the aperture and focus of a Canon EF/EF-S Lens (Canon, Tamron, Sigma, Samyang etc..) via USB.

Much easier than manually focusing or trying to stop down the aperture with masks.

This specially designed version is suitable for ZWO ASI6200MM cameras when used with a filter wheel. Works with the ZWO 5x 2" or 7x 2" filter wheels.

Super thin (11.5mm) design incorporates an adjustable tilt tuning mechanism to eliminate tilt (crucial with larger sensors) and adjust back focus. Easy to install using the existing filter wheel holes.

Compatible Lenses: Most classic Canon lenses should work correctly. Tamrom SP 150-600mm, Canon EF-S 10-18mm 1:4.5-5.6 IS STM, Canon EF-S 18-135 1:3.5-5.6 IS USM and Sigma 85mm f/1.4 DG HSM Art (for Canon EF Mount) lenses are not compatible at this time.

Immedaitely improved imaging sessions when using camera lenses with astro cameras. ASCOM drivers all setup simply and easily, providing support by all major imaging applications, definitely recommend.

This little device has been transformational for me. The new ZWO ASI6200mm camera produces beautiful images, but getting this integrated with Canon lenses is difficult without this adapter from AstroMechanics. The standard ZWO adapters require you to remove the tilt adapter from the camera in order to achieve focus with Canon lenses. But the AstroMechanics adapter fixes that so perfect image plane correction can be achieved. And, of course, the best bit is being able to control the Canon lens focus and aperture settings remotely through a simple USB cable. This works great with the supplied software, but also works superbly with ASCOM drivers so autofocus can be achieved using sequence capturing software like SGPro. It works like a charm. The build quality is excellent.
I should add that the first unit I received didnít have a locking pin for the lens, and in very cold weather this caused the bayonet mount to become loose. I reported this back to FLO and within a few weeks AstroMechanics had redesigned the bayonet mount to include a nice locking pin, and mailed me a complete replacement. So five stars to both FLO and to AstroMechanics for their outstanding customer support.
