TS-Optics 0.8x Focal Reducer for the TSAPO86PHQ 86 mm f/7 Quadruplet Flatfield Apo

TS 0.8x focal reducer for the 86 mm f/7 quadruplet flatfield refractor

The focal reducer improves the focal ratio of the 86 mm quadruplet apo to f/5.6 and shortens the exposure times accordingly. The focal length is reduced to 482 mm. The flat field of view of the apo is not changed. We recommend the corrector for sensors up to APS-C format. The optical performance is very good with these sensors. The reducer has been especially designed for the 86 mm quadruplet apochromat.

Connecting the reducer to the telescope:
The corrector is screwed directly to the focuser via the M68x1 thread. This guarantees an optimal fit without tilting.

Connecting the camera to the reducer:
An M48x0.75 external thread is available on the camera side. The working distance is 55 mm from the thread, whereby the external thread does not count, as it disappears in the connection adapter. Most astro cameras, mirrorless system cameras and SLR cameras offer adapters with which you can achieve exactly this distance. There is also an internal thread for 2" filters.
