Because of the relatively small dimensions of the microchips used in CCD imaging systems, composing the astronomical image (i.e., confirming the object's orientation and size relative to the chip orientation and dimensions and centering the object on the chip) can be a challenging issue, particularly in cases of faint diffuse objects.

This task is facilitated with Meade Plossl 25mm Illuminated Reticle CCD Framing Ocular (1.25"), Wireless Model 07568. Meade Framing Ocular 25 mm can be used in either of two ways:
(a) by placing it in the telescope's eyepiece-holder, after which 1.25" Meade CCD Framing Ocular is replaced with the CCD camera ; (b) in conjunction with a flip-mirror device.

Framing Meade Ocular 07568 displays in evenly illuminated red LED light the rectangular frames of all popular CCD chip sizes, including all Meade Pictor Series CCD imagers, as well as the ST-5 through ST-8 and other imager brands. A lockable spacer ring fixes eyepiece focus, so that the focus of the eyepiece and the CCD imager can be made precisely parfocal. Meade Plossl 25 mm Framing Ocular 07568 facilitates the composition of celestial objects on the CCD chip.
