72033 SkyMaster Pro ED 7x50mm Porro Binoculars by Celestron

Celestron SkyMaster Pro ED binoculars are the ideal choice for amateur astronomers or anyone who observes at great distances. The SkyMaster Pro ED uses superior optics, coatings, internal parts, and housing materials. With large objective lenses, BaK-4 prisms, ED glass, and fully multi-coated optics utilizing Celestron's proprietary XLT coating technology, the view through a SkyMaster Pro ED sets the standard for astronomy binoculars.

ED Objective Lenses

Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual phenomenon common in magnified optical systems. SkyMaster Pro ED delivers edge-to-edge sharpness with excellent color correction and razor-sharp images.

Not all ED glass is created equal. Celestron's high-quality ED glass delivers brighter, sharper images than non-ED binoculars. The difference is especially apparent in low-light conditions.

Coatings and Prisms

All of Celestron SkyMaster Pro ED's lens surfaces are fully multi-coated and feature Celestron's proprietary XLT optical coating technology. These powerful coatings, similar to the ones you'll find on our observatory-grade telescopes, decrease reflectivity for higher optical throughput across a broad range of the visible light spectrum. What's more, the prisms inside the binocular are made of high-quality BaK-4 glass, further boosting light transmission. Working together, the fully multi-coated lenses and BaK-4 prisms deliver more light from your target to your eye for brighter, more detailed views.

Objective Lenses

The 50mm objective lenses offer plenty of light-gathering ability for superior low-light performance. The objective diameter-to-magnification ratio is ideal for scanning the skies, observing the Moon and planets, and exploring all the best deep-sky objects. Celestron SkyMaster Pro ED also makes an excellent choice for long-distance land-based viewing–especially at dawn or dusk.

The Body

Custom-designed rubber armor and a durable chassis protect your SkyMaster Pro ED binocular from damage without weighing you down. Viewing through SkyMaster Pro ED binoculars is comfortable for eyeglass and non-eyeglass wearers alike, thanks to the retractable eyecups and nearly 21mm of eye relief. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses by twisting the eyecups down. For those who do not wear eyeglasses, the eyecups position the user's eye behind the eyepieces at the correct distance for optimal viewing.

Ways to Observe

The Celestron SkyMaster Pro ED binocular is tripod-adaptable. You can use a binocular tripod adapter (not included) to mount it on any standard photographic tripod or monopod for extended viewing or digiscoping (photography through the eyepiece).

SkyMaster Pro ED's eyepieces are threaded to accept standard 1.25" astronomical eyepiece filters. Adding the right filter can deliver game-changing views for terrestrial and celestial observing. For terrestrial observation, filters can reduce the brightness of sand, snow, and water. For nighttime viewing, filters can cut glare, minimize eye strain, increase contrast, and even combat the effects of light pollution. Remember, the binocular needs a set of two filters.

82052 Regal Premium Tripod by Celestron

The perfect tripod should be stable yet lightweight and easy to operate, requiring minimal knob twisting and lever flipping. The Celestron Regal was designed to be your perfect tripod. It is lightweight (6.04 lb.) and compact, yet it can hold up to almost 9 pounds of equipment.

The Celestron Regal Tripod is topped with a two-way fluid pan head. The single handle makes it easy to move the head around, while two knobs, located on the same side of the head make it easy to adjust the tension of the pan and tilt. A quick release plate with standard 1/4-20 thread mount makes it easy to attach a spotting scope, binocular, camera, or small telescope to the tripod. The quick release plate also doubles as a balance rail allowing the optic to be balanced when attached to the tripod. For additional peace of mind the quick release plate has a safety mechanism which prevents it from sliding completely out of the pan head without pushing the release button.

The aluminum legs of the Regal Tripod are fully adjustable, not just in length, but in their angle as well. Each leg is made up of four sections that can be shortened or lengthened with the flip of a simple lever lock. This makes it easy to make the tripod a little taller or a little shorter as your terrain or needs change. Each leg can also be set to three different angles. If the place you need to set up your tripod is not perfectly flat, the ability to adjust the angle of one or more legs makes all the difference.

With the center column fully extended, the maximum height achieved is nearly 69 inches (59 inches with the column down). The center column of the Regal Tripod does more than just go up and down. The bottom end of the column holds a retractable balance hook. This simple device can make all the difference in the stability of your tripod, especially on windy days. Just hang something heavy from the hook like a backpack and you'll be amazed at the difference. When the hook is not needed, it retracts up into the center column to stay neatly out of the way.

Two of the legs come with padded wraps, providing protection for your shoulder when carrying and making it more comfortable to make adjustments during cold weather. The legs also feature retractable spiked feet with the ability to change from rubber to spiked feet if the terrain requires it with the simple turn of the rubber pad.

Other features include bubble levels, located on the top of the tripod as well as on the side of the pan head, and a carrying case. The case is the perfect place to store your tripod when not in use, and makes it easy to transport via the shoulder strap.

93522 Dual-Axis Motor Drive for CG-4 Mounts by Celestron

Add tracking and tracking correction capabilities to any setup that uses a Celestron CG-4 equatorial mount. The right ascension motor drive allows the telescope to track a star's movement through the night sky, and the addition of a declination motor gives you the ability to make adjustments in all four directions with the included drive corrector hand controller.

With this drive system mounted on a properly polar-aligned telescope, the user can do visual observations or sketches without objects constantly drifting out of the field if view. Astrophotography is also possible when a mount has dual-axis drive with drive corrector capabilities.

The Celestron dual-axis motor drive system is powered by four D-cell batteries in a self-contained battery pack. The drive can be used in either the Northern or Southern Hemisphere. To change hemispheres (reverse the motor's direction), simply flip the "N/Off/S" switch on the drive corrector hand controller.

The drive corrector hand controller can be used to move the telescope at different speeds. This is achieved by choosing the desired speed on a switch marked "2x/4x/8x." Twice the sidereal rate, or 2x, is used for guiding on a star when doing astrophotography. The 4x speed is used to center objects in the eyepiece. The 8x speed can be used for centering objects in the finderscope as well as the eyepiece.

This package includes an RA and Dec motor, clutch, mounting brackets and hardware, drive corrector hand controller, and power pack.

93527 2" Mirror Diagonal with XLT by Celestron

There are few telescope accessories that work as hard or matter as much as a diagonal! An integral part of the optical chain, a good diagonal can make a big difference in the quality of the image you see. A 2" diagonal is required if you want to use 2" eyepieces when observing with your telescope. The larger 2" barrel allows you to see a bigger percentage of the telescope's light cone, which works wonders for capturing faint deep sky objects with low surface brightness.

The Celestron 2" Mirror Diagonal was built for superior performance. The housing is machined with precision instruments to make sure the optics stay perfectly aligned. The diagonal's mirror is tested with an interferometer, and is guaranteed to be 1/10 wave or better. The mirror's surface is covered with the same high performance XLT coatings used on Celestron's best telescopes, and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer.

This 2" diagonal threads securely to the rear cell of standard Schmidt-Cassegrain telescopes. To take advantage of the XLT Diagonal's extra light throughput, insert a 2" eyepiece into the barrel. If you want to use 1.25" eyepieces, slide the included 2" to 1.25" adapter into the eyepiece barrel and secure it with the thumbscrew. When you're not observing, store your diagonal in the included aluminum case for protection.

• 2" SCT mirror diagonal with high performance XLT coatings.
• 1/10th wave mirror is tested with an interferometer to ensure quality.
• Housing is precision machined to achieve and hold good optical alignment.

Standard Star Diagonals vs Dielectric Star Diagonal

The key specifications for a star diagonal are its reflectivity and its optical quality. This diagonal delivers top performance in both categories, with an over 99% reflective mirror and diffraction-limited optical quality. This ensures that virtually all the light collected by the telescope will reach the eyepiece without the diagonal affecting optical performance. Using a lower quality star diagonal can both dim the view and degrade optical quality. You can enjoy better views from your telescope by simply swapping out its diagonal for a premium one, like the Celestron Dielectric Star Diagonal.

The Aluminum Dew Shield provides a perfect, custom fit for 8" Celestron telescope tubes. The exterior of the dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit.

We've also constructed the cover cap from durable yet lightweight aluminum. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

If you're an astroimager who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration or the RASA, you're probably used to running cables out the front of the dew shield. Simplify and streamline your setup with the Aluminum Dew Shield's integrated cable management slot at the base. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit.

We've also constructed the cover cap from durable yet lightweight aluminum. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

If you're an astroimager who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar configuration, you're probably used to running cables out the front of the dew shield. Simplify and streamline your setup with the Aluminum Dew Shield's integrated cable management slot at the base. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.

Enhance your setup

When purchasing this item, you will receive 2x adhesive Celestron logo labels. Use them on your dew shield or anywhere else you like!

94054 Dew Heater Ring - 14" by Celestron

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 14" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and the 36cm RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

How it works

The Dew Heater Ring replaces the retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.

Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.

The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.

The Dew Heater Ring comes complete with:

• Dew Heater Ring
• Cable management clip
• Power jack extension cable
• Paper installation shield

Enhance your setup

To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring's power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers' heater output ports, or to a third-party controller's heater output port. (Note: the ring's integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).

We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.

• Heater ring provides the most efficient heating directly to the corrector lens to prevent the formation of dew
• Permanently mounts to your existing telescope tube for a seamless look–plus, you'll never forget to bring it with you
• Integrated thermistor continuously monitors the temperature of the corrector lens when used with the Celestron Smart DewHeater Controllers.
• Rigid, lightweight, and durable aluminum construction
• Included storage clip and cable management clip keep your cables organized

94175 Reducer/Corrector f/6.3 by Celestron

This combination focal reducer and field corrector lens accessory works with all Celestron 5", 6", 8", 9 1/4", 11" and 14" Schmidt-Cassegrain telescopes. 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, C6, 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.
