Orion 2" Zero Profile Photo Adapter (05308) $39.95
The Orion Zero Profile Camera adapter fits 2" telescope focusers on refractor and reflector telescopes. This extremely versatile astrophotography accessory will help you capture images with telescopes equipped with 2" focusers. Description Many prime focus camera dapters for use with astrophotography telescopes have housings which can add distance between your imaging camera and the focal plane. This can make it difficult to achieve focus with certain astrohphotography camera and telescope combinations. Not so with the Orion 2" Zero-Profile Prime Focus Camera Adapter, which couples your camera to a telescope for prime-focus astrophotography. The zero-profile design provides the closest possible in-travel...

Orion 0.5x Focal Reducer for StarShoot G3/... $58.49
This 0.5x focal reducer increases the area imaged by your StarShoot camera by a factor of 4. The reducer threads into the 1.25" nosepiece found on our StarShoot G3 or G4 imaging cameras to effectively reduce the focal length of the imaging telescope by half. Description The larger imaging area allows capture of larger star fields and deep-sky objects that may not fit entirely in your telescope's normal field of view. The Orion 0.5x Focal Reducer for StarShoot G3 or G4 Imaging Cameras has a two-element lens design, with antireflection coatings applied to all air-to-glass lens surfaces. The lenses are...

Orion Superwide 2" Prime Focus Adapter For... $64.99
Optimize your DSLR astrophotography setup and take full advantage of full-frame sensors with this handy adapter. The Superwide 2" Prime Focus Adapter provides the widest possible clear aperture to minimize vignetting -- darkening around the edges of the image sensor -- in astrophoto exposures, even when using cameras with large, full frame sensors. Nearly 10mm wider than standard T-adapters and T-rings, the Orion Superwide 2" Prime Focus Adapter boasts a clear aperture of 47.5mm for great DSLR imaging performance. Description Consisting of a 2" T-adapter with an integrated Canon EOS bayonet, this useful Prime Focus Adapter allows secure attachment of...

Orion Field Flattener for Short Refractors... $194.99
Optically fast refractor telescopes used for astrophotography are often plagued by significant field curvature, which is especially noticeable when using CCD/CMOS imagers and DSLRs with APS-C sized and full-frame sensors. This manifests in stars that are out of focus on the periphery of the image frame. Orion's handy field flattener solves this problem by providing excellent field correction while preserving the focal length attributes of your telescope. With the field flattener, stars will appear in sharp focus across the entire frame. Description Designed for use with refractors with focal lengths of 400mm to 660mm and focal ratios of f/5 to...

Orion Focal Reducer, 0.8x for ED Refractor... $194.99
Some of the most picturesque celestial objects are too large to fit in the field of view of an imaging refractor and camera. What's more, most deep space objects are very faint and therefore challenging to image without taking long exposures. The Orion 0.8x Focal Reducer for Refractors, designed for photographic use only, addresses these obstacles by increasing your refractor telescope's field of view while reducing the effective focal length by a factor of 0.8x, thereby providing a more optically "fast" focal ratio to increase astrophotography efficiency. Description Using the 0.8x focal reducer provides a larger field of view and...

Orion Field Flattener for EON™ 115mm (1028... $324.99
The Orion 0.8x Reducer-Flattener for EON 115mm ED Triplet Refractor will ensure wonderfully sharp photographs edge to edge with our premium EON 115 Apo. Description All refractors produce some amount of field curvature, which results in elongation of star images at the edges of the image frame. An optical flattener is recommended to correct for this. The 0.8x Reducer-Flattener provides excellent field correction (flattening), yielding sharp stars out to the edge of even a full-frame camera sensor. It also reduces the effective focal length of the EON 115 by 20 percent - from 805mm to 644mm (f/7.0 to f/5.6) -...

Orion Field Flattener for EON 104 Refracto... $389.99
Designed specifically for use with the EON 104mm ED-X2, this handy device corrects field curvature to eliminate misshapen stars near the field edge and yield an optically flat field for optimized imaging performance. Description To maximize imaging performance, a field flattener is needed to correct field curvature inherent in optically fast, short focal length refractor telescopes. Without a field flattener, refractors can exhibit bloated, misshapen stars near the edge of the telescope's field-of-view, which reduces astrophoto quality. As its name implies, using a field flattener produces a flat field with pinpont stars across the entire field of view for the...
