93514 AstroMaster/PowerSeeker Motor Drive by Celestron

Add right ascension (RA) tracking capabilities to any Celestron AstroMaster or PowerSeeker equatorial telescope, or any set-up that uses a Celestron CG-2 or CG-3 equatorial mount. This easy-to-install RA motor drive compensates for the Earth's rotation, so the telescope tracks a star's movement through the night sky from east to west. When the telescope mount is properly polar aligned and the RA drive is attached and running, the user need only make occasional adjustments in declination (Dec) to keep an object in the eyepiece for long periods of time.

The Celestron single-axis motor drive runs on a 9V battery, so there are no cords to get in the way. The drive can be used in either the Northern or Southern Hemisphere. To change hemispheres (reverse the motor's direction), simply flip the North/South (N/S) switch on the face of the motor drive. It is also simple to change the speed of the motor. A "Speed Rate Regulator" knob is located just under the power indicator, and can be turned in either direction to slow down or speed up the motor. Since solar system objects like the Sun and, Moon move through the sky at different rates than deep-sky objects do, this gives you the ability to match the motor's speed to the particular type of object you are observing.

93609 Universal Piggyback Mount by Celestron

A piggyback bracket is a simple astronomical accessory that can help you produce stunning photographs of the night sky. It allows you to attach a DSLR camera and lens to any Celestron SCT optical tube assembly and take advantage of the fact that your telescope has a dual-axis motor drive. When your telescope is running with the camera attached, you can take longer exposures without star trails, and capture details in objects that would have been impossible had your camera been attached to a photographic tripod or a telescope without a drive system.

Experiment with different camera lenses and subjects. Some photographers love to capture comets with a relatively long, fast lens, and the Milky Way, as well as a myriad combination of terrestrial and celestial scenes, are yours for the taking when you own a Celestron SCT, a piggyback mount, a DSLR camera, and a couple of lenses.

• A piggyback ride for your camera! Let your telescope do the driving while your camera takes beautiful wide-angle images of the sky.
• Use your own camera lenses to take photographs of the Milky Way, nebulae, the Moon, and more.
• Attaches easily to the top rear of any SCT in minutes.

93618 M42 Spacer Kit by Celestron

To achieve the best astroimages, it is important to attain the proper back-focus distance for your camera relative to the telescope it is being used with. If the back-focus distance your camera consumes is not exact, the performance at the corners of full frame imaging sensors will suffer—stars will appear elongated and not as pinpoints.

Example: RASA 8 with a ZWO ASI 183 MC PRO camera

• Required back-focus distance for RASA 8 with included M42 camera adapter: 25mm
• Back-focus consumed by ZWO ASI 183 MC PRO camera: 17.5mm
• To achieve equal back-focus distance, a 7.5mm M42 spacer ring is required

Celestron's M42 Spacer Ring kit includes three different length spacer rings to achieve the proper back-focus distance with our popular Celestron optical tubes and T-thread camera adapters.

How to Use

Depending your method of astrophotography (DSLR or CCD/CMOS), there are two ways to use the M42 Spacer Ring. If you are using a DSLR, place the desired M42 Spacer Ring between your T-Ring and your T-Adapter for your optical tube. If you are using a CCD or CMOS camera, place the desired M42 Spacer Ring between the camera and the T-Adapter for your optical tube.

Body

The M42 Spacer Rings are machined aluminum black anodized. The internal surfaces are blackened and glare-threaded to provide the highest contrast. Each spacer ring has a knurled surface, providing a great gripping surface for threading/unthreading. The M42 Spacer Rings are compatible with M42 x 0.75 (T-thread) camera adapters.

• Adjusts back-focus between your camera and telescope for the best astroimaging results
• Kit includes 3 spacer rings of different lengths (7.5mm, 12mm, 30mm)
• Threads to your T-Ring and T-Adapter with standard male and female T-Threads

93625 Universal 1.25" T-Adapter by Celestron

The Celestron Universal T-Adapter connects a DSLR or SLR camera body to a telescope with a 1.25" focuser or eyepiece adapter installed. The T-threads on the top of the Universal T-Adapter screw into a T-Ring (sold separately) that is designed to attach to the brand-specific mounting flange of your camera. The barrel end of the T-Adapter slides into the focuser, just like an eyepiece, and locks into place with the focuser or eyepiece adapter thumbscrew.

Please note that some telescopes, especially "fast" refractors and most Newtonians, may not have enough focus travel to allow the photographic image to come to focus when used in prime focus mode. In these instances, we recommend using the Universal Barlow & T-Adapter (#93640), which will double the magnification, but will allow the telescope to reach focus.

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

93633-A T-Adapter for Schmidt-Cassegrain Telescope by Celestron

This sturdy metal T-Adapter is the accessory of choice if you'd like to attach an SLR or DSLR camera to the rear cell threads of a Schmidt-Cassegrain telescope for prime focus photography.

To get started, you'll need the appropriate T-Ring for your camera body (#93402 for Nikon & #93419 for Canon EOS). Remove the lens from your camera and attach the T-ring in its place. Since the T-ring is camera-brand specific, it will snap right on just like a lens. Next, remove the diagonal and visual back from the rear cell of your telescope. Screw the Celestron T-Adapter onto the rear cell threads until secure. Now, thread the T-ring & camera onto the T-Adapter. That's all there is to it. The camera is now using your telescope as a giant telephoto lens. The magnification will depend on the telescope's focal length. For instance, a 300 mm camera lens is considered to be pretty powerful, right? Well, if you are using an 8 SCT at prime focus, you've got yourself a 2000 mm lens with a lot of light-gathering capability!

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon. If you want to do longer exposures of deep sky objects with this method, we suggest using a separate guidescope or off-axis guider and an equatorial mount.

• The Celestron T-Adapter attaches an SLR or DSLR camera to a Schmidt-Cassegrain telescope for prime focus photography.
• Threads on to the rear cell of Schmidt-Cassegrain telescopes.

94107 Variable Polarizer Filter, 1.25" by Celestron

When you want to selectively reduce the brightness of celestial objects for a customized view, the Variable Polarizing Filter is the perfect choice. Unlike regular Moon Filters and Neutral Density Filters, the level of brightness can be reduced to just 1% or as much as 40%. To make the adjustment, simply rotate the filter's lower ring and the image gets brighter or dimmer.

This filter does not alter the color of the object you're observing, making it a great choice for astroimaging, especially when imaging the surface of the Moon. By reducing the brightness, lunar details become more pronounced and defined. This filter can also be used to darken the blue-sky background when hunting for planets like Venus or Jupiter in the daylight, making the planet stand out from the background.

The Variable Polarizing filter threads onto any Celestron 1.25" eyepiece. Lastly, the filter can be threaded on both sides so you can stack it with other filters, such as color or neutral density, if needed.

• A customizable way to reduce brightness and glare on the brightest celestial objects like the Moon, Venus, and bright double stars
• Adjust the level of light transmission from 1-40% for the best possible view for your specific target and current viewing conditions
• Simple to use-just rotate filter's lower ring to adjust brightness
• Threads onto any Celestron 1.25" eyepiece

94112-A 1.25" Erect Image 45° Diagonal by Celestron

Did you know that most telescopes work well for daytime viewing as well as for astronomy? If you have a refractor or a catadioptric telescope (the Schmidt-Cassegrain is the most popular example), and you would like to use it for terrestrial observations, the most useful additional accessory you can buy is an erect-image diagonal.

If you look through your telescope with the standard mirror or star diagonal installed, you will notice that objects may be either upside down, flipped so that you see a mirror image, or a combination of the two. This is fine for observations of celestial objects, but it can be a little confusing when you are trying to track a boat as it moves through the water, or an eagle as he flies towards his perch.

Luckily, this is an easy problem to correct. Simply remove the standard diagonal from the telescope's focuser or visual back, and install the Celestron 45° Erect Image Diagonal. Now, when you insert an eyepiece, objects will be right side up and left-to-right correct. The 45° angle of this Amici prism diagonal is very comfortable for daytime observations, where the telescope is often in a horizontal position.

Please Note: Adding an erect-image diagonal to a Newtonian reflector will not result in images that are right side up and left-to-right correct. The optical design of a Newtonian will always produce images that are rotationally off in orientation. This does not mean that you can't use a Newtonian reflector during the day, it just means that you have to get used to objects oriented in unrealistic positions.

• A great accessory for daytime terrestrial viewing with your telescope.
• This 1.25" diagonal produces right side up and left-to-right correct images when used with refractors and catadioptric (Schmidt-Cassegrain) telescopes.
• Inserts into 1.25" focusers or visual backs. Accepts standard 1.25" eyepieces.

94115-A 1.25" Star Diagonal by Celestron

The Celestron 1.25" Star Diagonal slides into the focuser (1.25") of your refractor or catadioptric telescope and accepts standard 1.25" eyepieces, allowing you to view objects more comfortably. A diagonal that is angled at 90° helps avoid neck strain when looking through through the eyepiece.

Please note that a 90° diagonal will display images that are right side up, but left to right orientation will be reversed.

• Fits telescopes with 1.25" focusers or visual backs, 90° viewing angle, best for observing objects overhead.
• Accepts standard 1.25" eyepieces, Barlow lenses, and other accessories with a 1.25" insert barrel.

94182 Collimation Eyepiece 1.25 in by Celestron

The Celestron Cheshire Collimation Eyepiece is ideal for precise collimation of Newtonians and helpful for aligning Schmidt-Cassegrains. This special eyepiece fits into 1¼" focusers or diagonals.
