The APM 130/780 is a compact observing and imaging apochromat with a fast F6 focal ratio. Traditional APM-LZOS quality can be found in the lens cell, which as usual, is guaranteed to be a minimum 95% Strehl and offers extreme sharpness and contrast. As with all APM's telescopes, this already excellent optical performance is enhanced by the APM tube which is baffled to extract the last little bit of contrast from the optical design. Imaging accessories for the 130/780 include the optimised APM Model 1 Flattener and Massimo Riccardi designed APM Reducer. The latter changes focal length by a factor of x0.75, resulting in a 585mm focal length and ultra fast F4.5 aperture.

 

This is a special build of the 130/780. It is supplied as standard with an aluminium alloy tube including rings, handle, Losmandy format dovetail and aluminium case. It is fitted with a large capacity 3.7" focuser capable of handling heavy loads. The focuser is compatible with all APM correctors such as the APM Model 1 Flattener and APM M82 Large Reducer  These can be attached directly without the need for adapters. The focuser is also compatible with motor focus units such as the Lunatico Seletek.
