The Askar 107PHQ/130PHQ/151PHQ Universal Reducer has been developed as a dedicated accessory for the Askar 107PHQ, 130PHQ and 151PHQ astrographs. It guarantees excellent field correction, making it ideal for professional cameras and camcorders equipped with a full-frame sensor.
This reducer reduces the focal length by a factor of 0.7x, which in the case of the Askar 107PHQ astrograph gives a value of 524 mm at f/4.9, for the 130PHQ model 700 mm at f/5.4, and for the 151PHQ 740 mm at f/4.9. Such parameters allow not only to take breathtaking photos in a wide field of view, but above all to significantly shorten the exposure time.
The reducer enables the connection of cameras equipped with M68x1, M54x0.75 and M48x0.75 threads. • focal reducer dedicated to Askar 107PHQ and 130PHQ astrographs, compatible with full-frame cameras and cameras
