The Cassini C-80EFS features our unique Electronic Wireless Focuser enabling the user to focus the telescope without touching it for improved image viewing!
It's easy use up and down, left and right movement is great for beginners and casual star gazers alike!
The Cassini C-80EFS is mounted on an altitude azimuth yoke mount. The Mount features a slow motion altitude adjustment rod for precision adjustments and 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 telescope tube features heavy duty metal primary and secondary mirror cells. The optical tube assembly features an 800mm focal length. The Primary mirror is a 80mm 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 1.4 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 ?4 (1/4 wave in Sodium light). The finder scope is Cassini's Mars' Eye electronic Finder scope which helps by getting the observer behind the telescope without losing the surrounding field of view when targeting objects. Included with the C-80EFS are an 1¼? 6mm eyepiece (40° apparent field of view), an 1¼? 20mm eyepiece (52° apparent field of view), and a 2 element 3x Astroscopic Barlow.
