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

This allows you to install optional filters, which can be especially useful in imaging nebulae in light-polluted environments like the typical suburban backyard. For imaging broadband objects like galaxies and star clusters or objects from dark skies, remove the filter for more light-throughput and brighter images. Experiment with removable and interchangeable filters for results you can’t achieve with other systems’ fixed filters.

If you would like to try advanced image processing, Celestron Origin Mark II again has you covered. It can automatically save all your raw images, which you can retrieve by plugging in a USB thumb drive or by connecting to Origin’s built-in WiFi network to download the files to your computer wirelessly. Then, import them into your favorite software for manual editing and stacking.

And how about putting Origin to work for you while you sleep? That’s no problem with the scheduled observations feature. Just tell the app which objects you want to capture. You’ll wake up to an array of spectacular images.

Expand Your Astroimaging Possibilities with Celestron Origin

Celestron Origin Mark II delivers stunning deep-sky images right out of the box. But for experienced astrophotographers interested in experimenting with longer manual exposure times, there’s now an exciting new way to fine-tune performance: equatorial wedge mode, enabled by the Wedge for NexStar Evolution and the optional StarSense Autoguider.

By aligning Celestron Origin Mark II with Earth’s rotational axis, the wedge eliminates field rotation during tracking. This enables longer sub-exposures and allows imaging near or at zenith—ideal for capturing fainter details with greater clarity, since zenith (straight up) is generally the darkest part of the night sky. As with any equatorial setup, polar alignment is required before use, but the app will take you through an automated routine that makes it easy.

For exposure times beyond 30 seconds, we recommend pairing the wedge with the StarSense Autoguider. While Celestron Origin Mark II excels at short exposures (10–15 seconds), automatically rejecting frames with minor tracking errors, the Autoguider boosts tracking precision for longer manual exposures—reducing rejected frames and maximizing image quality. Together, the equatorial wedge and StarSense Autoguider offer a powerful toolkit for advanced users pursuing specialized longer-exposure imaging.

Gain a New Perspective Here on Earth

In addition to revealing distant worlds, Celestron Origin Mark II can also capture incredible views of land-based objects on Earth, day or night. During the day, you can manually slew to capture landscapes and scenery. At night, Origin’s fast optics and sensitive camera allow you to see things in very dim ambient conditions for almost night-vision-like performance. Look around your yard or campsite at night to see what you may be missing!

Take Your Astroimaging Studio Anywhere

Celestron Origin Mark II is a portable system that doesn’t require external WiFi or 5G networks, so you can easily take it to remote dark skies in any car. Perfect for exploring our southern skies from out in the bush!

Future Upgrades

When you invest in Origin, you can count on Celestron’s engineers as your long-term partners in astronomy. Our technical teams are hard at work developing even more upgrades and enhancements for your Origin. For example, we provide access to Origin’s camera for potential future upgrades as technology improves. We’re also developing all-new functionality for your Origin and the Origin app.

Here’s a sneak preview of what we’ll be rolling out in the coming months:

Mosaic Mode:- Capture wider fields of view by stitching multiple images together.

A:
That’s correct. Because the human eye is less efficient than CMOS sensors at low light levels, we are removing it from the equation. Origin’s sensor “sees” more photons in less time than your eye could and then delivers the images it captures to your phone or tablet. The result is “almost real-time” visual observing without an eyepiece. With Origin, you see much more detail in faint, deep-sky objects than you would through the eyepiece of a much larger telescope under dark skies.

Solar Maximum is now happening - it's the perfect time to explore the ever changing featured on our nearest star.

The Sky-Watcher Heliostar 76Hα is a specialized prominence telescope designed with advanced safety features to protect the observer’s eyes. It incorporates multiple technologies, including an infrared thermal reflection film to effectively block heat and a dedicated ultraviolet (UV) filter to eliminate harmful rays. These features work in tandem to minimize stray light, ensuring a safe and enhanced viewing experience.

The Sky-Watcher Heliostar 76Hα is a specialized solar telescope designed for enthusiasts eager to explore the Sun’s dynamic features, particularly solar prominences. With a 76mm aperture and a focal length of 630mm (f/8.3), it offers a balanced combination of portability and detailed solar observation.

Key Features:

• Hydrogen-Alpha Observation: The  Heliostar 76Hα utilizes a combination of front and rear filters to isolate the hydrogen-alpha wavelength at 656.28 nanometers. This narrowband filtering, with a bandwidth of less than 0.5 angstroms, enables observers to view solar prominences and surface details with exceptional clarity.
• Advanced Optical Design: Incorporating multiple technologies to protect the observer’s eye, the telescope features a thermal infrared reflection film, a special heat-blocking filter, and an ultraviolet light-blocking filter. These components work together to eliminate stray light and ensure safe solar viewing.
• Precision Focusing: Equipped with a 2-inch Crayford focuser, the  Heliostar 76Hα allows for smooth and precise focusing adjustments, enhancing the overall observing experience.

The  Sky-Watcher Heliostar 76Hα is an excellent choice for both novice and experienced solar observers, offering a safe and detailed view of the Sun’s dynamic phenomena.

Etalon Filter Technology

At the heart of most Hydrogen Alpha solar telescopes lies the etalon filter, a highly precise optical device that isolates the Hα wavelength from the rest of the Sun’s emitted light. An etalon is a type of interferometer, consisting of two parallel mirrors separated by a precise distance. The etalon works by reflecting light multiple times between the mirrors, selectively allowing only wavelengths that satisfy specific resonance conditions to pass through.

In the case of Hα solar telescopes, the etalon is designed to transmit light at the Hα wavelength while blocking all other wavelengths. The key to the etalon’s performance lies in its ability to tune the wavelength it transmits. This is achieved by adjusting the distance between the mirrors or by slightly tilting the etalon, which changes the interference conditions. This tunability is crucial because the Sun's emission at Hα can shift slightly due to Doppler effects as material moves across the Sun’s surface and atmosphere.

There are two primary types of etalon filters used in solar telescopes: single etalon and double etalon systems.

Single Etalon: A single etalon filter typically has a narrower bandwidth, providing high contrast for detailed solar observations but at the cost of limiting the field of view. This makes single etalon systems well-suited for viewing small, high-contrast features like prominences or filaments.

Double Etalon: A double etalon system uses two etalon filters in tandem to improve the wavelength selectivity, reduce the overall bandwidth, and enhance the contrast and image clarity across a wider field of view. Double etalon systems are preferred for more detailed solar studies because they can offer both a sharper image and better tunability, allowing for a more accurate depiction of solar dynamics.

Solis Etalon Technology: Sky-Watcher's Solis technology allows the Heliostar to achieve a 0.5A bandpass without the costly expense and complexity of a second etalon to achieve the same performance. This allows the observer to obtain detailed images of the solar disk right out of the box without any further expense. 

Trifid Tuner: Inside the Heliostar is Sky-Watcher's Trifid tuning system. This tuner applies physical pressure to the etalon plates allowing the observer to reach the desired Hydrogen-band. The Trifid tuner uses three support veins to provide a secure tuning for the etalon. 

What does Hα mean?

The Sun is mainly composed of hydrogen which it's been busily converting to helium for billions of years and will do for some billions of years to come. Hydrogen gas is energised by the Sun's radiation and emits light on certain wavelength. Hα refers to where one of these wavelengths. 

Viewing the Sun through the Heliostar 76Hα lets you discover the Solar chromosphere which is the outer layer of the Sun's atmosphere in great details.

Rather than looking at the Sun in the intense white light we see with our eyes or via a regular solar filter which reduces the overall intensity of the Sun's light so it can be safely viewed with a telescope, a dedicated Solar telescope reveals such details as prominences on the edge of the Sun's disks,  filaments, sunspots and more. 

As the Sun is such a dynamic environment, what you'll see through this telescope will change from day to day.

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.

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 Saxon 12" DeepSky CT Dobsonian Telescope features a powerhouse telescope with amazing light-gathering capabilities that's easy to use and transport.

This telescope is the retractable twin to the full-tube saxon 12" DeepSky Dobsonian Telescope and comes with the same specs of 305mm aperture and a focal length of 1500mm. Featuring a collapsible truss-tube dobsonian design, the optical tube can be retracted into a shorter length and locked down to ensure secure and easy transportation. This scope also comes with a paraboloidal primary mirror to eliminate spherical aberration allowing you to see wide-field views of the Moon, constellations and deep sky objects such as the Great Orion Nebula.

Assembly of the telescope requires no additional tools. You'll be pleased with how easy it is to use the saxon 12" DeepSky CT Dobsonian Telescope with its Dobsonian mount. Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.

The DeepSky CT Dobsonian Telescopes series comes in three sizes - 8", 10" and 12".

What is a Dobsonian telescope and why the tension control handle?

A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.

The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.

The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.

These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.

By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.
