Sky-Watcher Quantum 100ED APO Refractor Telescope

Description

• APO Quality - Quantum refractors are designed to assure virtual elimination of residual chromatic aberration ("false color") normally present in 2-element achromatic lens designs. Using extra-low dispersion (ED) glass, S-FPL51, for two of the lens elements and Schott glass for the other three lens elements, the Quantum 100ED 5-element design delivers crisp, high-fidelity views of planetary
• F/5 Focal Ratio - excellent for visual and wide field imaging use.
• Field Flattener – the Quantum 100 has a built-in two-element field flattening lens that provides sharps, in-focus stars across a large 43 mm image circle.
• Precision Linear Bearing Focuser - Optical focus is achieved by means of a mechanically ultra-smooth, backlash-free, precision linear bearing focuser with giant 3" diameter drawtube. This rotatable focuser offers 2-speed fine and micro-fine focusing adjustments with an engraved scale. Includes 2" eyepiece adapter.
• Carbon Fiber Optical Tube - Dent and scratch-resistant carbon fiber optical tube not only provides a stylish protective finish but also delivers excellent thermal stability and mechanical stiffness.
• EQ Mount Ready - All-metal tube rings and a CGE-style dovetail plate makes Quantum refractors ready to be mounted on any of Celestron's high quality imaging platforms, like the CGEM or CGEM Deluxe equatorial mounts.
• Retractable Carbon Fiber Lens Shade - For compact and safe storage.
• Aluminum Case - Offers protection for your instrument.
