Explore Scientific FFFR507X-00 3" Field Flattener .7x Reducer - Excellent Condition!
For Canon DSLR (they misspelled Canon - check out the photo!)

Explore Scientific’s 3” Field Flattener .7x Focal Reducer is a multi-faceted accessory designed to enhance your astrophotography experiences. As a field flattener, this piece addresses the edge-of-field aberrations caused by curved focal planes to ensure your night at the eyepiece will result in crisp, true images.

As a focal reducer, this device will reduce your f-ratio by .7, which results in a wider field of view, brighter images and less exposure time. Recommended for our 127mm and 152mm refracting telescopes, this field flattener/focal reducer boasts fully multi-coated optics.

While technically this was designed for the F/8 system, through user experiences and our subsequent testing we have concluded that our 3" Flattener / Reducer performs very well with our F/7.5 refractors.

We purchased these factory returns directly from Explorer Scientific. Optics have been cleaned & tested. 

Note: Does not qualify for the the Explore Scientific warranty, part of the serial number has been removed. Comes with ebay's 30 day money back guarantee which will give you plenty of time to inspect and test this fine item. Please contact us thru ebay if you have any questions. 

We ship promptly, usually the same day! 

Thanks!
