Orion ODK14 350/2380 Dall-Kirkham OTA

Description

Capture faint planetary nebulae and high-resolution galactic structures using the Orion ODK14 350/2380 Dall-Kirkham OTA 14-inch observatory astrograph optical tube assembly. Designed and manufactured in the United Kingdom by Orion Optics UK, this f/6.8 telescope features a 350mm (13.78 inches) aperture and a 2380mm focal length, delivering 0.33 arcsecond Dawes resolving power and reaching magnitude 14.6.

The Orion ODK14 350/2380 Dall-Kirkham OTA features an elliptical Suprax primary mirror, spherical secondary mirror, and an integrated doublet field corrector lens with 97% reflective Hilux multi-layer coatings. Its structural twill carbon fiber shell features matte internal anti-reflective coating, fixed mechanical mirror retainers, and a 3-inch dual-speed rack and pinion focuser with a 10:1 micro-drive. Weighing 24.00 kg (52.91 lbs), this 14-inch astrograph provides uncompromising rigidity on observatory tracking mounts.

Key Features of Orion ODK14 350/2380 Dall-Kirkham OTA

Engineered for observatory-grade long-exposure astrophotography, this 14-inch Orion Optics UK ODK astrograph combines an Optimized Dall-Kirkham optical system with an integrated doublet corrector. Its flat-field optical design and carbon fiber chassis deliver pinpoint stars across modern full-frame camera sensors.

• 350mm (13.78 inches) aperture with 2380mm focal length and versatile f/6.8 optical speed
• Optimized Dall-Kirkham optical design with elliptical primary and spherical secondary
• Integrated doublet field corrector lens for edge-to-edge flat-field astrophotography
• Hilux multi-layer reflective coatings delivering 97% total optical reflectivity
• 133mm secondary mirror obstruction (38.00% diameter, 14.44% area)
• 3-inch dual-speed rack and pinion focuser with 10:1 micro-drive and rigid lock
• Genuine multi-layer twill carbon fiber structural shell with matte internal coating
• CNC-machined primary cell with fixed mechanical retainers to prevent mirror shift

14-Inch Optimized Dall-Kirkham Optics & Full-Frame Field

The 350mm Suprax optical train works with the internal doublet corrector to eliminate coma, astigmatism, and field curvature across full-frame sensors. With 97% Hilux coatings, this 14-inch Orion ODK astrograph supports useful magnifications from 50x up to 700x.

3-Inch Precision Focuser & Carbon Fiber Structure

Supporting heavy imaging cameras and planetary filter wheels requires a tilt-free focuser platform. The Orion ODK14 features a 3-inch rack and pinion focuser with 10:1 planetary micro-reduction to hold heavy camera trains securely. Its low-expansion carbon fiber shell eliminates thermal drift during extended deep-sky observation runs under cold night skies.

• 3-inch dual-speed rack and pinion focuser with 10:1 planetary precision micro-drive
• Twill carbon fiber tube shell engineered to eliminate temperature-induced focus shifts
• CNC-machined aluminum support rings mounted to a heavy Losmandy-style dovetail bar
