William Optics Gran Turismo GT 71 II APO Astro Package - Striking Red Edition

The William Optics Gran Turismo GT 71 II is a compact apochromatic telescope that stands out with its stunning red and white design. With remarkable color correction and image sharpness, it sets a high standard in the world of compact telescopes.

At its core, this exceptional telescope features a three-element APO-ED optics system. Utilizing synthetic fluorite, an advanced optical material known for its low dispersion, the GT 71 II ensures outstanding image clarity. The FPL-53 glass used in this telescope, produced by the renowned Japanese company Ohara, is recognized for its high Abbe number and superior chemical stability. Each lens is crafted with precision using carefully selected glass types and coated with SMC for exceptional sharpness, detail, and contrast.

Included in this package is the FLAT 6A III, a top-tier focal reducer and flattener. Constructed from high-quality optical glass by Ohara, this component is compatible with full-frame sensors as well as APS-C and M4/3 formats, enhancing your astrophotography capabilities.

The telescope tube is securely mounted with CNC-machined clamps that include a Vixen socket, allowing for attachment of a finder or guider. Additionally, a versatile Vixen/Arca-Swiss foot is included for easy mounting on a mount or photographic tripod.
