• Designed to fit 32mm counterweight shafts
• Sturdy lock knob keeps the counterweight safely on the shaft
  

Whether you are enhancing your mount setup or buying a replacement part, the counterweight is there to balance weight of the optical tube (OTA) and accessories on the other side of the Right Accession (RA Axis). If you add accessories to your telescope setup (ie camera, guider, etc), you may need to add additional counterweights to off-set the weight.

If the balance is off on one-side or the other, it can do damage to your OTA and setup, the motor gear, and/or may have issues with tracking accuracy. You can add additional counterweights to improve the responsiveness to the system by reducing the mass inertia, though you need to make sure you space out the counterweights along the shaft to reduce damage to your setup and that it is cost-effective and worth it for your telescope setup.

This counterweight comes with a sturdy knurled knob locks to safely hold in place on the counterweight shaft. The counterweight is designed to fit 19mm counterweight shafts

CELESTRON’S BEST OPTICS

What makes the view through a CPC Deluxe HD unforgettable? It all starts with the newest EdgeHD optical system. This unique design corrects for both coma and field curvature, providing aberration-free images and pinpoint stars across the largest imaging sensors and all the way to the edge of the widest eyepieces

Read more about how EdgeHD outperforms competing optical systems by downloading the EdgeHD whitepaper.

All EdgeHD systems include Celestron's StarBright XLT coatings on all optical surfaces for brighter images and increased light transmission. Plus, every EdgeHD optical tube is Fastar compatible. Simply remove the secondary mirror and attach a third party lens assembly and you’re ready to image the night sky at ultra-fast f/2.

ULTIMATE VERSATILITY

Customers and reviewers have hailed the CPC Deluxe an all-around top performer, equally well suited to a star party or a university astronomy course. The beefy dual fork arm mount anchors the telescope for ultra-precise tracking, but weighs just 29 kg and includes rugged carrying handles to make setup quick and easy.

As soon as you turn on your CPC Deluxe HD, you’ll be guided through a simple SkyAlign procedure. The telescope walks you through centering any three bright objects in the eyepiece. From there, it’s ready to locate and track more than 40,000 celestial objects.

To customize your experience under the stars, CPC Deluxe HD is compatible with all of Celestron’s latest accessories. Add StarSense AutoAlign and your CPC will align itself in under 3 minutes. Or add the SkyPortal WiFi Module and control your telescope using a smartphone or tablet.

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 11" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and 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 plastic 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.

The Celestron Dew Shield DX is an essential accessory that protects your optical tube in the field. It prevents excess moisture in the air from forming condensation on the corrector lens. A dew shield also helps block stray light from entering the telescope for better viewing and astroimaging. Use the Dew Shield DX on your 6” and 8” Schmidt Cassegrain, EdgeHD, and RASA (with single dovetail) optical tubes with confidence.

Construction

The Dew Shield DX provides a perfect, custom fit designed specifically for 6” and 8” Celestron optical tubes. The Dew Shield is built from durable PE plastic that is flexible but strong. Extra padding has been added at the tube attachment edge to create a stronger fit on the optical tube. The felt-lined interior absorbs any additional stray light and excessive moisture, creating optimal contrast when viewing and imaging. The large dovetail cutout has been made both wider- to accommodate a 4” wide dovetail rails, as well as deeper, to create a more solid connection with the optical tube.

Attaching the Dew Shield to your optical tube is easy thanks to the Velcro attachment points. Whether your optical tube is 6” or 8”, simply adjust the Velcro for the correct fit.

Transportation and Storage

To save space when not in use, roll up your Dew Shield DX for easy transport and storage.

Celestron EdgeHD 11 OTA

See the Universe in HD
EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view...

True Astrograph Quality
Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.

Improved Performance
Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron’s StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.

Mechanical Features
In addition to Celestron EdgeHD 11 OTA optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.

• Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
• Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
• Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

Individually Tested
Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.
