USED GEAR INFORMATION

This flattener is in great condition. The glass is clean and there are no cosmetic imperfections on the body of the flattener.

Description

The iOptron field flattener reduces the normal field curvature inherent in all refractors to provide you with images that are sharply focused out to the very corners of your 35mm or large format CCD imager frame. Stars look sharp and point-like all the way across the field.

This 2” iOptron field flattener is designed for iOptron’s Versa 108 ED refractor, but also is compatible with most f/5 to f/7 refractors.

Scarlett H. ★★★★★

The glass arrived spotless and the body shows zero scuffs—exactly as described. Screwed it onto my scope and the stars came out pin-sharp across the whole frame.

Lucy ★★★★★

I was pleasantly surprised how well this used flattener corrects coma in my images—the glass is pristine and the body feels solid despite being pre-owned. It threaded onto my focuser without any wobble.

Lucy B. ★★★★★

The glass is spotless and the body has zero scratches, exactly as described. It threaded onto my telescope smoothly and the stars at the edges of my test shots look round now, not elongated.
