    Askar 0.7x Full-Frame 2.5" Reducer f/3.9 for Askar FRA400 72mm & FRA500 90mm Telescopes

    Askar provides a brand-new F3.9 full frame reducer for FRA400 astrograph, further reducing the focal length and thus shortening the exposure time on its original 400 focal length and f/5.6 focal ratio design basis. The reduction factor is 0.7×, and the reduced focal length is 280mm, which can satisfy most deep-sky astrophotography. The back focus is standard 55mm. The reducer has built-in M48×0.75 thread, easy for the attachment of 2" filters.

    Note: This item may or may not have the 'Askar' brand imprinted on the item as pictured above. It just varies from batch to batch.

It’s a very nice Alt/Az Mount. Very easy to use and gives good results most of the time. You need to take time to level the mount head well and balance your scope. Using. 25mm lens to begin with star and planetary alignment is good. Once centred it will track very well
