• Celestron 93609

The Celestron Piggyback Mount is a great accessory for all observers interested in deep-sky astrophotography. This mount allows you to attach your camera, with its lens, to the top of the telescope.

Its unique design also allows you to fit your NexStar telescope's Star Pointer on top of the Piggyback so that you can accurately navigate your telescope and conduct astrophotography at the same time.

The Piggyback adapter mounts to the rear cell of the 5, 6, 8, 9.25", 11" and 14" SCT's.

• CELESTRON 94191

The Counterweight Bar Assembly is a metal rail that runs the length of the telescope tube. It attaches to both the front and rear cells of an 8" SCT.

Once the Bar Assembly is in place, counterweights can be attached to it and moved along its length, as well as perpendicular to it, for better dynamic balancing. Each Counterweight Bar Assembly comes with mounting hardware and one 2.5 lb. weight.

Specifically for use in prime focus, deep-sky imaging or astrophotography with Schmidt-Cassegrain telescopes, the Radial Guider is compact and sleek in design. This accessory makes it possible to simultaneously photograph and guide through the optical tube assembly of your telescope. The Radial Guider also eliminates the problem of differential flexure, because you’re both guiding and photographing through the telescope.

The Radial Guider is compatible with Celestron’s C5, C6, C8, C9¼, C11 and C14 telescopes and comes with a unique prism angle adjustment screw. It must be used with a guiding eyepiece, camera T-Ring and drive corrector (dual axis preferred). Primarily for use with catadioptric telescopes, but also works on refractor telescopes having adequate back focus.

This guider is a tremendous improvement over conventional off-axis guiders. Not only is the angle of the prism tunable, but it also maintains a fixed rigid camera orientation while still offering users the freedom to move the guiding eyepiece radially about 135°.

• CELESTRON 94175

This combination focal reducer and field corrector lens accessory works with all Celestron 5", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes as well as most other brands. This clever accessory makes it possible to have a dual focal ratio instrument, without sacrificing image quality. The Reducer/Corrector is f/6.3 for C5, C8, C9¼ and C11 telescopes and f/7 for the C14 telescope.

If offers wide fields of view with any Schmidt-Cassegrain telescope. Used for astrophotography, it reduces exposure time by a factor of 3.

Celestron doesn’t offer a f/6.3 Schmidt-Cassegrain telescope, because the design is impractical, with a large central obstruction, and resulting loss in contrast. This, added to the inability to utilize longer focal ratios for certain objects, led Celestron to design the four-element, fully multicoated f/6.3 Reducer/Corrector. Results are amazing both visually and photographically.

Fits Celestron and Meade telescopes

• CELESTRON 94178

Increase your field of view by over two times for wide field lunar and filtered solar imaging.

The NexImage Reducer Lens replaces the 1.25" barrel and threads directly into the NexImage housing.

• CELESTRON 93712

Celestron's Neximage has established itself as the first-choice webcam adapted for astronomy. Based on a popular CCD chip it is ideal for lunar and planetary photography.

It fits in place of your 1.25" eyepiece and connects to a USB port on your laptop or PC. Supplied software captures video of your target then processes it to simulate a long exposure. The software allows you to discard frames where the atmosphere was unsteady and takes out tracking errors. The resulting images can be very impressive.

Neximage and its software are easy to use and make an excellent route into astrophotography.

• CELESTRON 93625

Universal 1¼" T-Adapter fits any telescope that uses a 1¼" focuser or visual back.

• CELESTRON 93633-A

For all Schmidt-Cassegrains. It threads onto the rear cell. Use a T-ring specific to your barnd of camera to connect an SLR or DSLR body.

• CELESTRON 93635-A

This T-Adapter allows you to attach your 35mm SLR camera to the prime focus of your Nexstar 4 Telescope or spotting scope. This arrangement is used for terrestrial photography and short exposure lunar and planetary photography. It can also be used for long exposure deep-sky photography when using a separate guidescope.

A T-Ring to match your specific brand of 35mm SLR camera is also required. These are available here on our web site.

• CELESTRON 93640

Universal 1¼" T-Adapter. Similar to #93625 but in addition includes an integral 2x Barlow lens which can be used visually or photographically.

• CELESTRON 93643

This deluxe Tele-Extender is designed for eyepiece projection astrophotography on an SCT. To use it, replace the star diagonal by an eyepiece of your choice, place the tele-extender over it and attach your camera body via a T-ring.
