• 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.

• Most Practical f/5 Telescope
• Outstanding Light Gathering Ability
• Super-smooth Azimuth Movement
• Tension Control System
• 2″ Focuser with a 1.25″ Adaptor
• 5 Years Sky-Watcher Limited Warranty

The Ultimate Light Gatherers

The Dobsonian telescopes are named after John Dobson, an amateur astronomer who designed a very simple but effective telescope, where the key factor is a large aperture for little money. His idea was to mount a Newton telescope on an easy-to-use alt-azimuth mount that does not need time-consuming alignments.

The Sky-Watcher 10″ Dobsonian is a large aperture Newtonian reflector telescope with f/5 focal ratio, make it ideal for wide field and deep-sky observation. Big aperture means better light gathering power and with this Sky-Watcher Telescope you are able to see prominent deep-sky object such as nebulae, star cluster and many more. It's also an excellent telescope for viewing planets such as Jupiter, Saturn and its rings and more. 

To top it off, the Sky-Watcher Classic 250P Dobsonian is equipped with a 2″ Crayford focuser and focuser locking screw to allow easy use of either eyepiece size.

Tension Control System
The Tension Control System allows you to adjust the friction setting; to increase or reduce the amount of resistance when moving the tube on the wooden mount, so you always have the appropriate resistance. The secret of the design is to correctly balance the optical tube with the specially designed handles (found on the base) and this adds enough friction and tension to allow the tube to move easily when nudged or to stay solidly in position.

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.

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.

The Celestron CPC 1100 GPS is a rock-solid dual fork arm mount and large aperture at an affordable price: that's what makes the CPC telescope a favorite among experienced amateur astronomers.

Tele Vue NP127is

For 25 years, Tele Vue has pushed the boundaries of APO refractors, as well as eyepieces, to the recognised pinnacle of performance. The Tele Vue NP127is retains the exemplary wide field and planetary visual capability while adding new features to make imaging easier and more flexible.

Tele Vue was determined to make the NP series optically, mechanically, and functionally as perfect as possible for imaging up to 50mm diagonal chips without penalty to its near-ideal visual operation.

By applying the developments created for the TeleVue60is to the new NP127is and then going beyond the results speak for themselves.

The NP127is maintains its 127mm f/5.2 optical specifications yet with a redesigned 4-element optical system. The larger rear lens group absolutely minimises vignetting in formats up to 50mm measured diagonally across the chip. An optional field corrector is available so the corners of the newly brightened edges are virtually as perfect as the centre of the field. To prevent restriction of the larger converging light cone the focuser has a 3" front aperture and a 2.4" rear aperture.

The new drawtube has features allowing quick changes from visual to imaging operation. While imaging cameras can be rotated without changing focus (just remember to do new flats!). It also has the capability to correct for any residual focal plane tilt so the imaging chip is square on to the light path.

The imaging insert ring is threaded to accept Tele Vue's new Imaging System accessories including large diameter extension tubes, optical accessories, and camera/CCD attachments all with mating threads.

TeleVue builds and tests the rack and pinion focuser to hold more than 5kg of weight, yet still permit extremely fine focusing control via a 10:1 dual-speed pinion assembly (measurable with the optional Digital Micrometer Kit). The optional Focusmate driver also permits electric motorised control of the focusing process. The new Focusmaster software interface allows this entire procedure to be completed from a PC or laptop.

Tele Vue has been known for producing visual instruments "even better than you imagined". The new NP127is is evidence that they aim to achieve the same with their imaging equipment

Tele Vue NP127is Specifications

After a short wait, the "re-tweaked" TV127is is available. Never ones to rest, Tele Vue took the opportunity to to make small but meaningful changes to their flagship model. Both the optical and mechanical designs have been revised to reduce atmospheric defocusing sensitivity. The new lens prescription delivers smaller spot sizes over a broader wavelength range than before, while a new stainless steel front cell helps provide better thermal stability in extreme climates. Advanced multi-coatings are applied to maximize contrast and transmission. Still the fastest in the industry, there is just no competitive comparison considering its f/5.2 speed and flat-field.

Sky-Watcher does it again. An old favorite gets a complete facelift with new features and upgraded components!

The venerable Dobsonian reflector design has recently undergone some important upgrades and improvements: Skywatcher is pleased to introduce the all-new Collapsible Dobsonian complete with Crayford focuser – the ultimate in large aperture portability and performance.

This elegant truss tube design was carefully engineered to combine ease of use, extreme portability and consistent performance in an affordable package. Unlike other truss tube designs, the Skywatcher Collapsible Dobsonian does not need to be disassembled between uses. It transports as two compact pieces that can be assembled and ready to use in just seconds! It is easy to collimate once set up, and it holds its collimation throughout the evening!

The bearing system has been redesigned as well. The new Skywatcher Collapsible Dobsonians feature buttery smooth azimuth bearings. Even the twelve-inch model can be rotated with just the push of a finger. Like our traditional Dobsonians, the new Collapsible Dobsonians feature Skywatcher’s patented tension adjustment control on the altitude bearings. This eliminates the need and added cost of clumsy counterweight systems to balance the telescope.

To top it off, all of the new Collapsible Dobsonians are shipping with ultra smooth Crayford focusers.

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.
