The classic air-spaced, crown-and-flint, doublet achromatic refractor is reborn with the aim to produce superior-class optical figure in a short (f/6.5) focal length design with Explore Scientific Air-Spaced Doublet AR Series.
The new Sky-Watcher EXPLORER-300PDS Newtonian Reflector incorporates the same superb mirror-set as the Explorer-300P but with two significant advantages. A Dual-Speed 10:1 ratio focuser is now included for excellent focusing precision. Also the tube length has been slightly shortened to optimise performance for prime-focus photography.
High quality optical tube on the extremely sturdy CG-4
The new Omni XLT Series features refractor, reflector and Schmidt-Cassegrain optical designs coupled with our new 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 series features high quality optics. Using aspheric shaping technology in conjunction with hand-figuring the optics the Omni XLT presents an image with virtually no spherical abberation. We also added our famous StarBright XLT coating system to further enhance light transmission.
Over the years, ETX Series telescopes have provided novice astronomers quality, value and performance, with each new model bringing enhancements and improvements. The ETX Observer continues that legacy.
The Advanced C6-S is Celestron`s first new Schmidt-Cassegrain optical system in over a decade. The C6 is a totally unique aperture size. Our NEW 6” Schmidt-Cassegrain features a precision optical system with 1500mm focal length (f/10) and offers 40% more light gathering than a 5” telescope. All C6-S models come standard with Celestron`s StarBright® XLT coatings at no extra cost.
The Explore Scientific AR152 152 mm f/6.5 Air-Spaced Doublet is an excellent 6-inch class achromatic refracting telescope with push-pull collimatable lens cell, 2-inch heavy duty Crayford-sytle two speed focuser, good quality 8x50mm straight through finderscope, mounting rings with handle
