The Celestron T-Adapter-Barlow Lens Universal - 1.25'' can be used three ways; as a 2X Barlow for visual use, as a prime focus T-adapter, or as a “Barlowed” T-adapter to double the magnification.

Features:

1. As a 2X Barlow right out of the box. Insert any 1.25” eyepiece into the adapter to double the magnification, while retaining a comfortable eye relief of your eyepiece.
2. For prime focus photography. Unscrew the bottom section (glass element) to remove the Barlow and slide the chrome barrel into the telescope’s 1.25” focuser. Screw a T-Ring to the T Thread on top of the adapter. Attach to your DSLR or SLR camera.
3. As a barlowed T-adapter simply screw your T-Ring (sold separately) directly to the T-Thread and place into focuser. Good for imaging Planets to enlarge image.

Please note that some telescopes, especially “fast” refractors and 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, adding the Barlow to the T-Adapter will allow the telescope to reach focus.

In “Tele-Extended” mode, the Barlow doubles the focal length and f/ratio of your telescope, resulting in an image on the sensor or film plane that is twice the size of a prime focus image.

Prime focus and tele-extended photography are popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

Compatible Celestron Telescopes

Celestron 8" F/2 RASA - Capture spectacular wide-field deep sky images in seconds with Celestron’s portable astrograph, the 8” Rowe-Ackermann Schmidt Astrograph (RASA). This incredibly fast f/2.0 system is the perfect companion to today’s color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras. Thanks to its fast focal ratio and patented optical design, you can produce sharp, detailed images and, in many cases, skip the autoguider completely. Weighing in at just 17 pounds, it’s easy to transport your 8” RASA to the most remote dark sky locations.

RASA Performance Made for Everyone

The 8” RASA is an imaging telescope that delivers a flat field without optical aberrations for razor sharp stars across a wide field of view. It can capture stunning deep-sky astronomical images without the challenges typically presented by longer focal length instruments at a fraction of the cost of those systems.

The latest addition to the RASA family, this 8” version is a much more portable and affordable version of the heralded RASA 11, which was introduced to much acclaim in 2014. With the 8” RASA joining the lineup, a wider range of astroimagers can enjoy the benefits of the RASA design. It has many of the same thoughtfully designed features as its “big brother” RASA 11, including the integrated air-cooling system, internal filter mount, and sturdy CGE dovetail mounting bar.

Purely designed for imaging, the 8” RASA cannot be used visually. The prime focus focal plane is located at the front of the optical system, so it cannot accommodate a traditional eyepiece.

Shorter Exposure Times and Virtual “Real-Time” Observing

Since it is an F/2.0 optical system, imagers can use shorter exposure times to capture detail in faint objects. When combined with sensitive cameras and the proper “live stacking” software, the 8” RASA can provide an almost real-time observing experience. View images on a computer instantly that are brighter and more detailed than can be seen in much bigger telescopes with the naked eye.

Because shorter exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The 8” RASA’s relatively short 400mm focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required. Weighing only 17 lb, this optical tube pairs perfectly with a wide variety of mounts.

Ultra-Stable Focus System

With the launch of the 8” RASA, Celestron is unveiling a focuser design that mitigates lateral movement of the primary mirror when focusing, slewing, or tracking with the astrograph. Focusing is easier, more accurate, and more stable than ever. The key to the Ultra-Stable Focus System is two sets of precision bearings that are precisely aligned and tested during assembly to ensure optimal results.

Built for Today’s Latest Cameras

Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras. It is optimized for sensors with up to a 22mm diagonal, but performs well with sensors up to 32mm diagonal. The APS-C sized sensors used in many mirrorless cameras are a good choice. 42mm full frame sensors will also work, but performance will be poor at the edges of the sensor and field illumination will be reduced. Additionally, we do not recommend pairing RASA 8 with any camera body more than 4” in diameter. See the chart below to determine if your camera is compatible with RASA 8.

Unique Optical Design

RASA’s optical design is patented (US 2016/0299331 A1). The design consists of a Schmidt corrector, primary mirror, lens group, and optical window. The lens group contains 4 elements and utilizes rare-earth elements. Unlike many telescopes that only perform well over the visible spectrum (400-700nm), the 8” RASA’s optics are designed to perform over a wider spectral range, from 390-800nm. This allows more of the light emitted from the astronomical object to be sharply focused in the image.

With many imaging systems, adding an extra piece of flat glass such as a filter does not change optical performance. However, that is not the case with super-fast optical systems like the RASA. Our engineers addressed this by designing the RASA with a removeable optical window, so you can maintain peak optical performance if a filter is added or if a camera has its own optical window. Celestron offers a Light Pollution Imaging Filter designed specifically for the 8” RASA, which mounts in place of the optical window.

All refractive optical surfaces are coated with StarBright XLT coatings, while the primary mirror uses enhanced aluminum coatings. This maintains high light transmission through the entire optical system.

When compared with “Hyperstar SCT” systems, the RASA 8 provides better optical performance and field illumination.

Eyepieces - The 15 mm and 6 mm eyepieces can be used in any telescope with a 1.25” focuser. Each eyepiece is fully coated to improve light transmission and protect the optics. The 15 mm Kellner eyepiece offers a nice medium magnification view in most telescopes, and the 6 mm Plossl provides high magnifications, great for the Moon and planets, especially when seeing conditions are good.

2x Barlow Lens - Insert the 2x Barlow Lens between the eyepiece and the telescope and it doubles the magnification of any 1.25” eyepiece. That means the 15 mm Kellner included in this kit will double in power, effectively becoming a 7.5 mm eyepiece, and the 6 mm will provide the magnification of a 3 mm. Any other 1.25” eyepieces you already have will also work in this versatile accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Experiment to find the magnifications that are best for you and your telescope. T-threads are machined into this Barlow lens, allowing a user to attach a DSLR camera with the addition of an optional T-ring.

Filters - Colored filters can be used to bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1.25” eyepiece with the proper filter threads, so they are very versatile. Just screw one onto your eyepiece of choice and slide it into the focuser.

The #80A is a medium-blue filter that enhances the contrast of the cloud belts on Jupiter and the polar ice caps on Saturn. It also can be used to increase contrast on the Moon if you don’t mind the color shift.

The #25 filter is a deep red color and is a good choice when you want to define the polar ice caps on Mars. It’s also fun to use this filter when observing Jupiter. The #25 Red filter blocks quite a bit of light coming through your telescope, however, so it is best used on bright objects with larger aperture telescopes.

The Moon filter is one of the first accessories most new amateur astronomers buy, and for good reason! It helps block out a portion of the light the Moon sends into your eyepiece so that you can see details better. You can also try this filter on Venus; it helps you see the planet’s phases.

Cleaning Cloth & Case: Keep the micro-fiber cleaning cloth stashed in your AstroMaster Accessory Kit case so that it will always be handy. It’s much better to use a micro-fiber cloth on your optics than other wipes or tissue, as it does not leave a residue, and can be reused. Remember to blow or brush any dust particles off of your optics before rubbing them with the cloth.

The black plastic carry case has die-cut foam inside to protect and cushion your accessories. Keep each one in its appointed place when not in use and you’ll keep them looking and performing like new.

You can easily add a second auxiliary port to your Celestron mount with the Celestron AUX Port Splitter. This parallel adapter plugs into the AUX or hand controller port of your computerized telescope and splits it into two, allowing you to connect the Celestron StarSense AutoAlign, or another peripheral device, to your telescope and still keep the hand controller plugged in.

The Celestron C8-A is the direct (but much improved) descendent of Celestron’s revolutionary C8 that transformed the hobby of astronomy when it was unveiled in 1970. This rugged aluminum optical tube is only 17 inches long and weighs just 13 pounds, 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 2032 mm of focal length and 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 C8-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.

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.

A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you.

To use the Canon EOS T-Ring, remove the lens from your camera, and attach the T-Ring in its place, just as you would if you were mounting a lens. The telescope side of the T-Ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do.

You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor or spotting scope, the Universal T-Adapter (#93625), with its 1.25” barrel insert, is probably the best choice. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646).

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

If you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.

The hobby of amateur astronomy frequently takes the observer away from sources of AC power. After all, we are always in pursuit of the darkest skies possible, and that often means getting away from the city lights and going bush. The most common way to power your telescope in these situations is to use a commonly available, portable 12V battery pack or to use power from your car’s battery via the cigarette lighter.

The Celestron Car Battery Adapter is the accessory required for connecting any Celestron computerized telescope to a DC power supply or car battery. Plug the round post into the 12V input jack on the drive base of your telescope*, and insert the power connector into the cigarette lighter outlet in your car or on your power supply. The cord is 7.5m long, giving you plenty of reach between your telescope and 12V power source.

The barrel connector can be used with any telescope that uses a receptacle with an outside diameter of 5.5mm and an inner diameter of 2.1mm and a “tip positive” polarity.

*For use with the following telescopes:

• NexStar SLT Series
• NexStar GT Series
• CGEM Series
• CPC Series
• CPC Deluxe Series
• Advanced VX Series

Normally available for pickup or shipping approx. 2-3 business days from your order

ERGONOMIC DESIGN
