Orion AG8 200/760 Carbon Astrograph OTA

Description

Astrophotographers requiring portable prime-focus speed on mid-capacity tracking mounts rely on the Orion AG8 200/760 Carbon Astrograph OTA carbon fiber Newtonian telescope. Designed and manufactured in the United Kingdom by Orion Optics UK, this fast f/3.8 astrograph features a 200mm (7.87 inches) aperture and a 760mm focal length, delivering 0.58 arcsecond Dawes resolving power and reaching magnitude 13.3.

The Orion AG8 200/760 Carbon Astrograph OTA features a precision-annealed Suprax parabolic primary mirror with certified 1/10 PV wavefront accuracy and 97% reflective Hilux coatings. Its lightweight multi-layer twill carbon fiber shell incorporates a CNC 9-point mirror cell, an integrated 3-inch Wynn coma corrector, and a 3-inch dual-speed rack and pinion focuser with 10:1 micro-reduction. Weighing just 8.00 kg (17.64 lbs), this 8-inch astrograph provides exceptional portability and rigidity.

Key Features of Orion AG8 200/760 Carbon Astrograph OTA

Crafted for portable wide-field deep-sky astrophotography, this 8-inch Orion Optics UK astrograph pairs an f/3.8 optical path with an integrated Wynn coma corrector. Its lightweight carbon fiber body and 3-inch focuser slash sub-exposure times while maintaining razor-sharp star profiles across full-frame sensors.

8-Inch f/3.8 Suprax Optics & 3-Inch Wynn Corrector

The fast f/3.8 light cone path drastically shortens exposure times, while the integrated 3-inch Wynn corrector eliminates coma across large sensors. Featuring 1/10 PV surface precision and 97% Hilux coatings, this portable Orion astrograph supports magnifications from 29x up to 400x.

Lightweight Carbon Fiber Shell & 3-Inch Focuser

Field astrophotography requires lightweight mechanics that resist outdoor temperature changes. The Orion AG8 incorporates a twill carbon fiber tube shell that minimizes thermal expansion and dampens vibrations rapidly. Its 3-inch rack and pinion focuser provides a rigid, tilt-free platform for heavy filter wheels and cooled astrophotography camera setups.

• 3-inch dual-speed rack and pinion focuser with 10:1 planetary reduction gearing
• Lightweight carbon fiber body shell weighing just 8.00 kg for easy mount transport
• CNC-machined support ring set mounted to a heavy Vixen or Losmandy dovetail bar
