High Point 0.75X 2" Focal Reducer For RC Telescopes
The High Point 0.75X Focal Reducer will increase apparent field and reduce exposure times when paired with a Ritchey-Chretien telescope. This 2" slip-fit reducer has a 2-element optical design enhanced with fully multi-coated optics. RC's with an f/8 focal ratio will reduce to f/6, and those with an f/9 focal ratio shorten to f/6.75. The durable, black-anodized assembly can fit a 2" focuser or adapter and accept 2" barreled accessories through its anti-marring compression ring opening. The 0.75X Focal Reducer has a practical spacing distance of 70mm - 80mm, measured from the sensor to the reducer thread. This is typically enough space to add a guider, filter wheel, or any other accessories. The High Point RC Reducer has an image circle of 15mm, and therefore works best in conjunction with CCD or CMOS sensors that have a diagonal measurement of 15mm or less.
This is a focal reducer only; not a reducer/flattener.
