Telescopes & Astronomy

A T-ring converts a camera's mount to a standard T-thread. All camera adapters, including Celestron and Meade T-adapters and universal camera adapters, will fit this T-thread. Call for advice if your camera is not listed.

• Rigid, 16" long anodized aluminum bar used for coupling guide scope rings to an astrophotography telescope
• Attach guide scope rings to this mounting bar, then attach bar in piggyback orientation to imaging telescope
• Multiple holes along length of mounting bar allow rings to be positioned for long-tube or short-tube guide scopes
• Pre-drilled holes allow easy attachment to Orion SkyView Pro, Sirius, and Atlas mounted telescopes with tube rings
• Astrophotography telescope must be equipped with tube rings in order to attach guide scope ring mounting bar

• 1.25", 90-degree mirror diagonal features sophisticated dielectric coatings with highly efficient 99% reflectivity for peak performance
• Twist-tight clamping mechanism grips inserted eyepieces more securely than typical thumbscrew-equipped diagonals - without scratching!
• Durable dielectric mirror coatings provide higher reflectivity for maximum brightness and contrast
• Machined and anodized aluminum housing features machine-threaded glare baffles to eliminate glare for great performance
• Nosepiece barrel threaded to accept 1.25" filters

• High-performance observational eyepiece filter markedly improves views of Mars
• Fully-coated Mars filter increases contrast to bring out subtle details on the disc of the red planet
• When using the Mars filter on a clear, dark evening you'll see polar ice cap detail, subtle mare shadings, duststorm and cloud activity
• Eyepiece filter dramatically improves views of Mars even in smaller astronomical telescopes
• Designed to fit 1.25" telescope eyepieces with filter threads. Metal filter cell construction.

• Reduce the amount of time spent waiting for your big GoTo Dobsonian to reach thermal equilibrium with the Orion Three-Fan Cooling System
• Three-fan set custom designed to fit the Orion XX14i IntelliScope, XX14g GoTo and XX16g GoTo Dobsonian primary mirror cells
• Enjoy optimized visual performance quickly
• Each fan boasts 33.4 CFM (cubic foot per minute) air flow to help significantly accelerate cooling of your Dobsonian telescope's optics
• Quiet fans operate without vibrations
