• The Meade 8” f/4 LX85 astrograph reflector optical tube assembly is a compact wide field telescope, with an immense amount of light grasp, thanks to the large 8” BK7 (Borosilicate) mirror and >90% enhanced reflectivity coatings. The f/4 system is incredibly fast, meaning with a camera it will collect a lot of light in a short time, perfect for taking shorter exposures while still recording all sorts of detail in the nebulae and galaxies.

  With an 800mm focal length, pairing this telescope optical tube with a DSLR or other astro camera will yield large and rich swaths of sky, perfect for framing any number of large deep-sky objects. And with the 2” linear bearing Crayford focuser, trying pairing it with a low power 2” eyepiece with a large apparent field of view. From a dark-sky location away from city lights, objects such as the Veil Nebula will reveal structures you may not have seen before. The focuser features a 10:1 reduction fine focus knob, brass compression rings (so you don’t mar the barrel of your eyepieces or camera adapters) and a 2” to 1.25” step down adapter (also with a brass compression ring).

  The telescope is designed to reach focus with any DSLR camera, along with a host of other imaging accessories, and the long 83.2mm back-focus helps ensure compatibility with various equipment. In order to allow visual use as well, a 35mm long 2” diameter eyepiece extension tube is also provided, allowing most all 2” and 1.25” eyepieces to work with the telescope.

  Depending on the size of your camera sensor, an optional coma corrector is recommended to eliminate the inherent coma in a reflector design. This would prove beneficial when using low power 2” eyepieces, or camera sensors above ~4:3 format.
