The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astro photography. The flattener reduces the telescope's focal length by the factor of 0.85 and increases the useful field. As a positive side effect, the necessary integration times are significantly reduced. The field curvature that is unavoidable at most telescope systems is reduced to a nearly irrelevant level when using sensors up to APS-C format (24x16mm). Optimal distance M48 - focal plane: 55mm

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
