Meade 8" f/4 LX85 Astrograph Reflector Optical Tube

Introducing the Meade 8” f/4 LX85 astrograph reflector optical tube assembly, a compact wide-field telescope that boasts exceptional light-gathering capabilities. This is achieved through the incorporation of an impressive 8” BK7 (Borosilicate) mirror and advanced >90% enhanced reflectivity coatings. The f/4 system operates at a remarkable speed, allowing it to efficiently capture substantial light within short exposures, making it ideal for capturing intricate details within nebulae and galaxies.

With its 800mm focal length, coupling this optical tube with a DSLR or any astro camera produces expansive and detail-rich portions of the sky. This makes it perfect for framing a multitude of large deep-sky objects. Additionally, the inclusion of a 2” linear bearing Crayford focuser enables seamless pairing with a low-power 2” eyepiece featuring a wide apparent field of view. When situated in a dark-sky environment far from urban light pollution, this telescope unveils new structural nuances within objects like the Veil Nebula. The focuser offers a 10:1 reduction fine focus knob, safeguarded by brass compression rings to prevent any damage to eyepiece barrels or camera adapters. Furthermore, a 2” to 1.25” step-down adapter is included, also equipped with a brass compression ring.

Designed to achieve focus compatibility with DSLR cameras and a variety of imaging accessories, the telescope boasts an extended 83.2mm back-focus distance, ensuring versatility with different equipment. To facilitate visual observations, a 35mm long 2” diameter eyepiece extension tube is provided, enabling compatibility with most 2” and 1.25” eyepieces. The package includes a range of accessories such as hinged tube rings and a Vixen-style dovetail rail, a 26mm Super Plössl eyepiece, an 8x50 finder scope, and a cooling accelerator fan affixed to the rear mirror cell.

Depending on the dimensions of your camera sensor, it's recommended to consider an optional coma corrector to mitigate the inherent coma associated with reflector designs. This proves especially advantageous when utilizing low-power 2” eyepieces or camera sensors exceeding the ~4:3 format.
