This large-format ﬁeld ﬂattener, designed for photography with the Orion EON

115mm and 130mm f/7 triplet refractors, ﬂattens the focal plane for astro-imaging

without affecting the focal length of the telescope. When imaging with a CCD or

DSLR camera, the far edges of the ﬁeld of view will appear sharper when using

the ﬁeld ﬂattener with your EON telescope.

Connection to Telescope

The 3" Field Flattener threads directly onto the 3" dual-speed Crayford focuser of

the Orion EON 115 and 130 f/7 triplet refractors, for a rock-solid connection. The

Field Flattener has M92x1.0 male threads, which mate with the female threads

on the focuser. First remove the accessory collar from the focuser by turning the

knurled ring counterclockwise, as shown in Figure 1. Then screw the ﬂattener

into the focuser.

The optimal backfocus distance (distance from the rear ﬂange of the ﬂattener,

excluding the M48 thread, to the camera sensor) is 51.5mm. However the ﬂat-

tener is known to provide sharp images at up to 5mm either side of this distance.

Connection to a DSLR Camera

The 3" Field Flattener features M48x0.75 threads on the camera side, wider than

the typical T-mount (M42), to minimize vignetting and provide better illumina-

tion of full-frame camera sensors. Thus, for DSLRs you will need an M48 DSLR

adapter – a wider version of the standard T-ring.

Connection to a CCD Camera

Most CCD cameras require less backfocus than a DSLR camera. That means

you will need to add spacing as needed to ﬁll the 51.5mm of required distance

to the Field Flattener. M48 (2") spacers are available from third party vendors.

Figure 1. To install the ﬁeld ﬂattener, A) remove the accessory collar as shown, then B)

thread on the ﬁeld ﬂattener until tight.
