Galileo 1100x102 Catadioptric Telescope
The Galileo FS-102DX2 is mounted on Galileo's Super Glide Altitude Azimuth mount. It's easy use up and down left and right movement is great for beginners and casual star gazers alike. It also makes terestrial viewing easy when an erecting lens is used. The Super Glide mount features slow motion controls in both axis for precision adjustments. The Mount is attached to a very sturdy fully adjustable pre-assembled metal tripod with retractable rubber feet. The tripod also features an accessory tray with slots to place 4 1¼″ eyepieces or lenses. The optical tube assembly attaches to the mount by an adjustable tube clamp which in combination with the adjustable counter balance weights ensures easy fluid movement of the telescope at all times. The telescope tube features heavy duty metal primary and secondary mirror cells. The telescopes optical tube assembly is finished out with a large 2″ format focus tube. 2″ to 1¼″ adapter is included as well.The Galileo FS-102DX2 optical tube assembly features a catadioptric design providing an 1100mm focal length (catadioptric correcting lens is fully multi-coated). The Primary mirror is a 102mm heavy duty mirror cell with push / pull collimation screws. The primary mirror is aluminized with Silicon Monoxide Quartz overcoat providing 92% reflectivity and a resolving power of 1.14 arc seconds. The secondary mirror has an obstruction of approximately 25% linear (approximately 6% of the total area). The optical tube assembly is diffraction limited at λ4 (1/4 wave in Sodium light). The finderscope is Galileo's Mars' Eye electronic Finderscope which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects. Included with the FS-102DX2 are an 1¼″ 6.8mm to 16mm zoom eyepiece (42° apparent field of view @ 6.8mm) an 1¼″ 20mm eyepiece (52° apparent field of view) and a 3 element 3x Barlow.1100mm x 102mm Catadioptric Optical Tube AssemblyDiffraction limited Optical Tube Assembly (λ4)Galileo Super Glide Altitude Azimuth Mount w/Slow-Motion ControlsFully Adjustable Heavy Duty Pre-assembled Steel Tripod w/Accessory TrayGalileo Mars Eye Electronic Finderscope2″ Metal Helical Rack & Pinion Focuser2″ to 1¼″ Adapter1¼″ 6.8mm - 16mm Zoom Eyepiece1¼″ 20mm EyepieceGalileo Planetarium CD-ROM w/Instructional Telescope TutorialOne Year Warranty
