Orion Field Flattener for EON

104mm ED-X2 Triplet Refractor

The Orion Field Flattener for EON 104mm ED-X2 was designed exclusively

for the EON 104 ED-X2 Triplet Apo Refractor, to flatten the focal plane for

astro-imaging without affecting the focal length of the telescope, even on full-

frame camera sensors. For photography only, not visual use, this high-per-

formance 2" field flattener is highly recommended for obtaining the highest-

quality images with your EON 104.

This field flattener has an optimal backfocus distance of 55mm (distance from

threaded attachment plate to camera sensor). It comes with interchangeable,

thread-on adapter plates, one with 42mm (T-mount) male threads, the other

with wider, 48mm male threads (which are equivalent to 2" filter threads).
