Askar 0.6x Full-frame Reducer Professional Astronomical Accessory for 103APO Telescope

Askar 0.6x Full-frame Reducer Professional Astronomical Accessory for 103APO Telescope

Description:
- The 0.6x reducer can bring the 103APO's focal ratio down to F4 while also providing field flattening. 103APO adopts a detachable tube design, where the rear part of the tube can be removed when using the 0.6x reducer, allowing the telescope to have the necessary length to achieve an F4 focal ratio.

- The 0.6x reducer adopts a quadruplet design that also supports a 44mm full-frame image circle. The overall weight is 0.98kg. The back focus from the M48 thread is a standard 55mm. At the camera end, we have equipped three sizes of adapter, M68x1, M54x0.75, and M48x0.75 for easy subsequent connection and use. At the same time, the built-in M48x0.75 2-inch filter thread can be used to install filters directly. The overall CNC machined, both end threaded metal caps prevent ash when not in use.
