Filter for astrophotography transmits 90% of light at 656.3nm wavelength (H-alpha).

If you're using a monochrome CCD camera like Orion's Parsec 8300M, these specialized "line" filters are the perfect complement. Orion's 2" Oxygen-III Filter has a full-width half maximum (FWHM) bandpass of just 7nm, ensuring high-contrast images, even in heavily light-polluted or brightly moonlit skies. The filter can be used separately or in combination with a filter wheel for advanced tri-color imaging of emission nebulae.

Effectively blacken the background sky with extra-narrowband filters to produce striking, high-contrast astrophotography of emission nebulae. Orion's 2" Extra-Narrowband Sulfur-II Imaging Filter will do just that. It is ideal for use with monochrome CCD cameras like Orion's Parsec 8300M.

254mm (10") aperture and 1200mm focal length reflector telescope optical tube provides vivid, close views of deep-sky and solar system objects.

Orion's 8” aperture deep-sky imaging specialist boasts features usually reserved for much pricier astrophotography telescopes. In fact, the Orion 8” f/3.9 Newtonian Astrograph’s powerful imaging performance easily exceeds what’s achievable with many premium apo refractors costing thousands of dollars more.

Whether you're looking to upgrade from your present telescope mount or are seeking a more robust equatorial system for your new telescope, you can't go wrong with the smooth-moving, sturdy Orion AstroView EQ. Its newly designed equatorial head has a dovetail attachment plate similar to that on the Orion SkyView Pro, Sirius, and Atlas mount heads. The AstroView supports up to a 5" refractor tube and has enclosed worm gears, an azimuth adjustment, and dual manual slow-motion controls. Hinged center brace adds stability to the all-aluminum adjustable tripod. Includes polar alignment scope and high-walled accessory tray. EQ-3M single- and dual-axis computerized drive systems are available separately. Weighs 27.5 lbs.

We love those premium "apo" refractors as much as the next guy. We just don't think you should have to work a second job or put the family heirlooms on eBay to own one. Now you won't, thanks to our amazingly affordable Orion 80mm Extra-Low Dispersion Refractor Telescope Optical Tube.

Take your astrophotography to the next level with this set of 1.25" Luminance (IR cutoff), Red, Green, and Blue telescope filters. They're designed for creating high-quality composite color astrophotos with Orion monochrome imaging cameras or similar monochrome cameras.

• Create dazzling three-step RGB astrophotos - just like the pros


• Red, blue, and green filters plus the haze-eliminating Luminance filter give you stunning results


• Works with the Orion Orion StarShoot Deep Space CCD Monochrome Imager II


• Includes 5-filter wheel that lets you dial-in the filter you want for observing or photography!

Now, every imaging session can be as productive as possible with the Nautilus Motorized 4x2" Filter Wheel. Not only does it ensure automatic and trouble free filter transitions for your monochrome imaging setup, but it saves precious imaging time. To easily transition filters for tri-color, RGB or LRGB imaging, just load up to four filters into the Nautilus 4x2" and use your imaging software to change filters automatically. Let your PC do the work while you grab the separate exposures you need through each filter. Versatile threading and adapters provide several attachment methods, including T-threads for focusers with camera adapters, a removable 2" nosepiece to allow maximum field illumination to the camera, and a removable T-thread adapter for camera attachment.

The new Nautilus motorized filter wheels are the best way to ensure automatic and trouble free filter transitions for your imaging setup. To easily transition filters for tri-color, RGB or LRGB imaging, just load up to seven filters into the Nautilus 7x1.25" and use your imaging software to change filters automatically. Versatile threading and adapters provide several attachment methods, including T-threads for focusers with camera adapters, a removable 1.25" nosepiece to allow maximum field illumination to the camera, and a removable T-thread adapter for camera attachment.

Autoguiding has revolutionized the capture of deep-sky images by mechanizing the tedious and tiring method of "manually" guiding an exposure, which involved staring endlessly into an illuminated reticle eyepiece while tweaking your mount's electronic drive controls by hand to keep the stars pinpoint sharp. Until now, the problem has always been the lack of a simple, affordable autoguider camera to do the job. Problem solved.

The Orion StarShoot G3 Deep Space Monochrome Imaging Camera has been designed with performance enhancing features and software that until now have been reserved for much more expensive CCD imagers. Built around the popular Sony interline ICX419AKL Monochrome CCD chip, which boasts a 752 x 582 pixel array with sensitive, 8.6 micron by 8.3 micron pixels, the StarShoot G3 is capable of detecting fine details in celestial objects. This bigger, 1/2" format CCD sensor usually isn’t available in cameras priced as low as the StarShoot G3, and it provides a much larger imaging field of view than cameras equipped with 1/3” format chips so you can shoot more sky in far less time.

• An affordable and capable monochrome astrophotography camera for anyone interested in taking amazing tri-color or LRGB astrophotos with a telescope and specialty filters
• Features a 1/2" format monochrome CCD sensor and an on-board thermoelectric cooler (TEC) which are normally only available on much more costly cameras
• High-tech features such as 16-bit A/D conversion, regulated thermoelectric cooling, on-board fan and more
• The Orion StarShoot G3 Monochrome can also be used as a dedicated, high-performance, low-noise autoguider with ST-4 output jack built right in
• Complete Orion Camera Studio software is included for easy image capture, processing, and sharing of your astrophotos. ASCOM drivers are also included for use of the StarShoot G3 Monochrome with other imaging software programs, or for autoguiding use
