Kendrick Secondary Heater Wrap-Large heaters are designed to work with Newtonian/Dobsonian secondary mirrors that are attached to a "stalk", but don't have enough exposed mirror to use our "Split-Ring" or Elliptical style heaters. The heater warms the stalk, and that heat is then conducted to the mirror.

How to choose the right model for your telescope?

It's easy! You just need to make a few easy measurements. We can't help you to choose because we don't have your telescope in our shop and there are literally thousands of models and "eras" of these telescopes. Even models that have been in continuous production for decades frequently change the mirror assembly design, so we don't want to suggest a model that might not work. The good news is .... you have the telescope in-hand, so a few quick measurements is all it will take to find the perfect fit.

All models include easy electrical connectors and a neoprene wrap-around insulator which greatly enhances the performance of these heaters as it prevents the warmth generated by the heater from dissipating into the atmosphere.

The power draw is incredibly low using only 0.3amp or 4 watts at 100% Controller setting

This model is a simple strip-heater that can be mounted either horizontally or vertically. There are 3 sizes available.

Are you worried that when you take pictures in the evening or wet environment, your DSLR lenses or small refractor can’t work perfectly because of the dew on the lenses? And then you also need to wipe the lenses, again and again, to keep the lenses dry and clean.

The Haida Anti-Fog Belt is designed to avoid dew on lenses by warming them up by using an advanced graphene heating material that distributes the heat safely and evenly. There are 3 modes for you to choose from: low heat (35-45°), medium heat (45-55°) and high heat (55-65°). The Anti-Fog Belt can withstand temperatures as low as -40°C.

The belt comes with a USB port and a pouch so you can put it in your bag easily and conveniently. When you have trips or plans of climbing high mountains like the Alps or Himalayas to take pictures, this belt will also develop a large impact.

The Bintel ND96 13% Neutral Density filters reduce the glare by only partially transmitting (only 13%) of the reflected light uniformly across the entire spectrum. Not only will you see more surface features, but you can study them in greater comfort. These filters also reduce irradiation, which is the distortion at the boundary between light and dark areas, such as along the lunar terminator. Screws directly into the eyepiece barrel.

The Moon’s disk, even at partial phases, is intensely bright with reflected sunlight. The glare washes out most of the craters, rilles, and other surface details from view, particularly in telescopes of 6 inch aperture and larger.

With standard filter threads (M25.5 x 0.6) it can be screwed into almost any 1.25" eyepiece, 1.25" diagonal or can be stacked with other coloured filters to enhance lunar and planetary detail.

The ND96 filter may also be employed in the splitting of close double stars where one of the binary pair significantly exceeds the other in brightness.

Comes in plastic case for clean, safe keeping.

Users will experience incredible views without breaking the bank or impinging on your telescope's balance. They represent what is perhaps the best buy today for astronomers on a budget or for beginners. But don't be fooled by their low prices - these might well turn out to be all the eyepieces you will ever need!

The Bintel Plossls are available in a 1.25" barrel size and 9 different focal lengths ranging from 6mm to 40mm. The 4mm, 6mm and 9mm models are great for high power planetary and lunar observation. The 12mm and 15mm are perfect intermediate focal lengths, performing well on both deep-sky and planetary subjects. The 20mm and 25mm models would be excellent choices for low power scanning of open star clusters and viewing larger galaxies. The 32mm and 40mm models offer a wide field and are superb for wide field scanning, detailed observations of large diffuse subjects or as a finder eyepiece.

• All eyepieces are fully multicoated (FMC) for maximum light transmission
• High quality lenses provide the best-possible sharpness all over the field of view
• Blackened lens edges reduce light scattering and improve contrast
• Fold-down rubber eyecups to keep out stray light
• Comfortable eye relief at all but the shortest focal lengths (As in all Plossl eyepieces, eye relief can get tight at the shorter focal lengths but this is design constraint, not a fault of these eyepieces)
• Includes two end caps
• 50 Apparent field (degrees)

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

The Celestron C9.25-A is an unusual size with its 9.25” aperture and 2350 mm focal length, but many consider it to be the Goldilocks of optical tubes—not too big, not too small. This rugged aluminum optical tube is only 558mm long and weighs just 9kgs, making it easy to transport and set up. But the views are much more impressive than what you’d expect from such a compact instrument. The tube offers a focal ratio of f/10 with the added versatility of Fastar (see below).

It is equipped with Celestron’s patented StarBright® XLT optical coatings, which visibly increase contrast and light transmission for brighter deep space images and shorter exposure times. With StarBright XLT, you’ll be able to discern subtle details while viewing the Moon and planets as well as faint galaxies and nebulae.

The Celestron C9.25-A can be mounted on a multitude of computerized telescope mounts thanks to its CGEM-style dovetail bar. This iconic optical tube provides the best balance of portability, handling ease, light gathering ability and price ever offered to the amateur astronomer.

Fastar Technology

In 1997, CCDs were making a name for themselves in the astrophotography world, quickly supplanting traditional film photography thanks to their speed and convenience. This was the year that Celestron joined forces with the Santa Barbara Instruments Group (SBIG) to produce Fastar, a revolutionary add-on to Celestron’s hugely popular Schmidt-Cassegrain (SCT) optical system.

With Fastar, the SCT’s secondary mirror can be removed and replaced with a field-flattening lens assembly (sold separately by third party manufacturers) so that a CCD camera can be used in the front of the telescope at the f/2 focus of the instrument’s primary mirror. The potential of the Fastar system is staggering: exposures are 25 times shorter than if the camera was placed at the instrument’s native f/10 focus. Imagers can capture galaxies and nebulae with exposures of just 30 seconds.

StarBright XLT coatings

StarBright XLT is Celestron’s revolutionary optical coating system. It consistently outperforms all other coatings in the commercial telescope market. There are three major components that make up our StarBright XLT high-transmission optical system design:

• Unique enhanced multi-layer mirror coatings made from precise layers of aluminum, SiO2 (quartz), TiO2 (titanium dioxide), and SiO2 (silicon dioxide). Reflectivity is fairly flat across the spectrum, optimizing it for both imaging and visual observing.
• Multi-layer anti-reflective coatings made from precise layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide). Hafnium—a rare element that costs nearly $2,000 per kilogram—gives us a wider band pass than the titanium used in competing coatings.
• High-transmission water white glass is used instead of soda lime glass for the corrector lens. Water white glass transmits about 90.5% of light without anti-reflective coatings; that’s 3.5% better than uncoated soda lime glass. When water white glass is used in conjunction with StarBright XLT’s anti-reflective coatings, the average transmission reaches an astonishing 97.4.

Celestron X-Cel LX series eyepieces offer a 60º apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.

The X-Cel LX eyepiece body is made of black-anodized aluminum. The pop-up eyecups make it easy to adjust the height for different users. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers. A threaded rubber grip around the center of the eyepiece barrel offers secure handling, even in moist conditions or with heavy gloves on. The 1.25” insert barrel is threaded to accept filters.

An extension tube can also be used for increasing image scale when doing projection photography.

The Celestron 2” Luminos Barlow Lens increases the magnification of your 2” and 1.25” eyepieces by 2.5x. The premium 4-element apochromatic optics are fully multi-coated for optimum light transmission and yield high contrast, true colour images.

The beautiful hard-anodized aluminum housing matches the eyepieces in the Celestron Luminos line. A centralized rubber grip helps to keep your hands securely on the barrel, even when your fingers are cold or you are wearing gloves. A brass compression ring just inside the top of the Luminos 2.5x Barlow grabs your 2” eyepieces gently but firmly when you turn the oversized thumbscrew. Once the thumbscrew has been secured in place, the brass ring keeps your eyepiece in the Barlow instead of relying on the tip of the thumbscrew itself, offering a better grip and protecting the barrel from scratches. A matching 2” to 1.25” adapter is included so that you can increase the magnification of all of your eyepieces, both 1.25” and 2”, in this versatile Barlow lens.

The insert barrel of the Celestron Luminos 2.5x Barlow is threaded to accept 2” filters. This is a nice feature, because you can change eyepieces without removing and reattaching the filter each time.

The Luminos series eyepieces offer a wide 82º field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractor or a Celestron EdgeHD telescope. The optical set consists of six or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Luminos eyepieces are parfocal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.

The Luminos eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eyecup. Simply twist the rubber grip to adjust the height of the eyecup. The insert barrel is threaded to accept filters.

Celestron X-Cel LX series eyepieces offer a 60º apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16 mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required.

The X-Cel LX eyepiece body is made of black-anodized aluminum. The pop-up eyecups make it easy to adjust the height for different users. Turn them in one direction to extend the length, and the other direction to provide a flat surface, preferable to most eyeglass wearers. A threaded rubber grip around the center of the eyepiece barrel offers secure handling, even in moist conditions or with heavy gloves on. The 1.25” insert barrel is threaded to accept filters.
