Correction. This is just in from the LX200GPS group: If you're referring to LORRI, it's actually a narrow angle (field of view=0.29¡ã), high resolution (4.95 ¦Ìrad pixels), Ritchey-Chr¨¦tien telescope with a 20.8 cm diameter primary mirror, a focal length of 263 cm, and a three lens field-flattening assembly. It also has a silicon carbide optical system, designed to maintain focus over the operating temperature range without a focus adjustment mechanism. Throw in the lack of an Earth atmosphere to view through and we're looking at something significantly more powerful than even the top-of-the-line LX200.

It was posted in the LX200GPS discussion group, of which I'm a member: -- Joe Hi all, I was looking at NASA's New Horizons spacecraft which is currently on the way to Pluto and found that it's major imager is a 10 inch SCT telescope with a F10 focal length and a 1024x1024 CCD camera.  I doubt that it's Meade (couldn't find out) but for those of us with the 10inch LX200 I'm sure you can relate. Just thought it was interesting...
