About the Celestron Omni XLT 102 - 4" Refractor Telescope w/German Equatorial Mount...
The Celestron Telescope Omni XLT Series features refractor, reflector and Schmidt-Cassegrain optical designs coupled with the Celestron Omni CG-4 Heavy-duty German Equatorial Mount and sturdy tripod featuring 1.75" stainless steel legs and center tray for superior rigidity and vibration dampening. Along with the stable platform of the CG-4 mount the Omni XLT telescope series features high quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics the Celestron Telescope Omni XLT presents an image with virtually no spherical abberation. Celestron has also added their famous StarBright XLT coating system to further enhance light transmission.
At the heart of the Celestron Omni 102 XLT is a high quality refractor Celestron Telescope with hand chosen lens for absolutely the best optics available. We''re talking about 4" aperture with a limiting stellar magnitude of 12.5 and 1.14 arc seconds of resolving power. Couple that with a 1000mm focal length and focal ratio of f/9.8 presents an image with virtually no spherical abberation. With superior optics and a stable platform the Celestron Omni XLT series is a great choice for astrophotography. Use the optional dual-axis motor drive and Celestron CCD Camera to enjoy sharing the view of both planets and deep sky objects!
The Celestron Omni XLT 102 - 4" Refractor Telescope w/German Equatorial Mount comes backed with a two year Celestron warranty and will endure as long as your Celestron Telescope and fascination with the Cosmos!
