Outstanding Optics

Upholding the triplet design of the Askar 140 APO Refractor, the 0.8x reducer is also made with three lens elements for superb quality and color correction. Supporting a full frame 44mm image circle, this 0.8x Reducer corrects curvature around the edges of the image, as well as reducing the focal length of the Askar 140 APO. Taking its native focal length of 980mm down to 784mm, its focal ratio is reduced to f/5.6, making for an incredibly speedy system! This wider field of view allows you to capture large areas of the night sky, making it ideal for large nebulae and faint celestial objects.

All of the Necessary Adapters

This Askar 0.8x Reducer offers multiple points of connection through its numerous included adapters. The front thread utilizes a M84*1 thread, allowing you to connect this reducer to your telescope. On the camera side, two different adapters are present to allow you to achieve the perfect backfocus. A M54*0.75 and M48*0.75 offers incredible versatility, allowing you to attach numerous different optical assemblies into your imaging train. An additional M48*0.75 2-inch filter thread allows for your filters to be threaded directly into your telescope! Its robust CNC machined body instills great stability and security within your optical system.
