ASKAR 0.7x REDUCER FOR 107PHQ, 130PHQ & 151PHQ Telescope Optical design Riccardi-Honders

Optical design Riccardi-Honders

Maximum height

This low profile dual speed 2" rack & pinion focuser is incredibly stable and boasts a high payload capacity of 8kg

Adding this adapter to the ESATTO will result in the same overall thickness as the stock focuser

but without losing any of the pre-set alignment

ASKAR 0.7x REDUCER FOR 107PHQ, 130PHQ & 151PHQ Telescope Optical design Riccardi-HondersThe Askar 0. 7x Flattener Reducer for 107PHQ, 130PHQ & 151PHQ telescopes is a 3" corrector for full frame sensors. The flattener reducer is a triplet design with one element of ED (Extra low Dispersion) glass. The 0. 7x reduction factor shortens the focal ratio of the 107PHQ to f 4. 9,the 130PHQ to f 5. 4 and the 151PHQ to f 4. 9, shortening the exposure time and increasing the field of view. When paired with this flattener reducer, the focal length
