TS FMA360 Manual Telephoto Lens for Astrophotography

Teleskop-Service offers the FMA360, a purely manual telephoto lens for astrophotography. The mechanics are reduced to the essentials. The result is an inexpensive telephoto lens with top optics with a fabulous price-performance ratio. The apochromatic lens has telescope quality.

The focusing on the FMA360:

Instead of an elaborate focuser or helical focusing like conventional camera lenses, the FMA360 achieves focus by a sliding rear tube and simply twisting the lens mount. This is extremely accurate. Once the desired focus is achieved, the position is simply fixed with the lock ring. There is no wobbling and no shifting.

The connection of the camera to the FMA360:

The 2-element corrector is screwed to the end of the tube. Starting from the M48x0.75, the working distance is exactly 55 mm to the sensor position - ideal for mirrorless system cameras, DSLR or astro cameras.

Attaching to the telescope or photo tripod:

The FMA360 fits into any standard finder shoe, e.g. TS-Optics, Vixen, Skywatcher, GSO ... due to the universal dovetail. The CNC rings are adjustable to set up the telephoto lens exactly parallel to the telescope. The dovetail also has a 1/4" photo tripod thread at the base. This really allows you to attach the telephoto lens to almost any mount or telescope.
