- 900mm f/8.8 Apochromatic Refractor
- Manual Equatorial Mount
As an apochromatic refractor, instead of the more common reflectors, catadioptric, or achromatic refractor designs, the XLT 102 ED has enough aperture to keep you duly entertained as a viewer along with serious high-contrast, wide field optics for astrophotography. Apochromatic refractors can't visually show you the things an 8-14" Schmidt-Cassegrain or reflector can, but they can make superior images of these same items for you to enjoy. The focuser barrel directly accepts SLR cameras with an optional T-mount for your make, and with the motor drive and polar axis finder you'll be able to get great results with only a minimum of experience. Apochromatic refractors are also far superior should you wish to enjoy some terrestrial viewing; just add a 45° erect image diagonal for an amazing, stationary-style spotting scope.
The XLT 102 ED arrives with Celestron's classic CG-4 German-type equatorial mount, a simple and understated support which you can easily operate manually with nothing more than a star map and red flashlight. Properly aligned and centered, you can easily trace the movement of your object of interest with just a single control as it moves along the night sky. Everything required for immediate use is included in this package.
