Explore Scientific 3" Flattener With .7X Focal Reducer
Introducing this High quality and functional 3" Flattener With .7X Focal Reducer by Explore Scientific. This 3" Field Flattener .7x Focal Reducer is designed to enhance your astrophotography experiences and is a multi-faceted accessory. This addresses the edge-of-field aberrations caused by curved focal planes as a field flattener to ensure that your night at the eyepiece results in crisp, authentic images.
It will reduce your f-ratio by .7, which results in a broader field of view, brighter images, and less exposure time as a focal reducer. Recommended and supported for our 127mm and 152mm refracting telescopes, this boasts fully multi-coated optics and comes with two adapters to entertain different focuser sizes.
This was technically designed for the F/8 system; we have concluded through user experiences and our subsequent testing that our 3" Flattener / Reducer performs very well with our F/7.5 refractors. Buy to see it for yourself! Add to cart now!
