TS Line Newtonians by Orion Optics

TS stands for Telescope-Service. We were so impressed with these Newtonians when we first saw them that we decided to give them our own brand name. All TS Newtonians feature good craftmanship, a well-made primary mirror cell made of metal and a 2" focuser. What we liked the most, though, was the very low weight of these telescopes when compared to similarly sized models of other manufacturers. This will allow you to put the telescopes on lighter mounts (or you will have better stability with any given mount). All TS Newtonians now feature 96% HILUX coatings, resulting in an altogether greater light-gathering capacity.

Easy Payment: We offer our customers several easy and fast payment methods. You will receive exact payment details when ordering or on request!

TS Line Newtonians Sorted By Size




A Few Basic Facts
Optics The image quality of these instruments is very good. Each mirror is guaranteed to give better than diffraction-limited images.

Primary and secondary mirrors are made of Suprax. This is a very homogenous mirror material with good thermic properties. Suprax is more or less similar to Pyrex.

What's more, since all mirrors are relatively thin (with no ill effects on image quality) they will cool down to ambient temperature quicker, thus enabling you to observe sooner than you would with thicker mirrors, or mirrors made of inferior material.
Mechanics The telescope's tube is made of aluminium and therefore very light-weight. The focuser, too, is made of metal and works smoothly. The mirror cell is well made and will hold the mirror precisely in position without pinching it.
Weight The most extraordinary feature of the TS Newtonians is their low weight. This makes the telescopes more portable and allows you to use lighter (and cheaper) mounts to carry the telescopes.
Mounting options We offer all TS Newtonians either as optical tube assembly (OTA) or on various equatorial mounts. If you are interested in a combination with another of our mounts that is not listed here please do not hesitate to ask - we will make a good offer.
96% reflective coating Each TS Newtonian features the new 96% Hilux coating. The advantage is obvious: 10% more light will reach your eyes when compared to traditional coatings, making for altogether brighter and more detailed images of deep-sky objects.
Optical Certificate All TS-Line Newtonians come with a Zygo Interferometric Test Report. The telescopes are checked before shipment. Some miscollimation may of course result from the transportation (which is easy to fix by the user), but other than that you have a carefree package and do not need to worry about the quality of the product.



TS Eyepiece And Accessory Case - Available with all Orion TS-Line Newtonians

150mm Aperture TS Newtonians
150mm of aperture offer great optical performance. At the same time the telescope is still small enough to be easily portable. Even small, lightweight mounts will carry the telescope with power reserves, allowing you to use heavy accessories or a guiding scope.

HILUX Coating
96% Reflectivity on Primary and Secondary Mirror

The Orion HILUX coating offers about 10% more light to reach the eyepiece compared with a standard coating. The image gets brighter and clearer.

Zygo Testprotokoll

Each telescope comes with a Zygo interferometric test report to prove its guaranteed optical quality.

2" Crayford Focuser for our TS-Line Newtonians:

All Orion TS-Line Newtonians come with a good quality 2" Crayford focuser. A 1.25" adaptor is of course included so that you can use most standard accessories.

The focuser is solidly built and offers a smooth focus motion even under heavy load. Accessories are clamped smoothly but firmly with a brass compression ring... Further Information on the Focuser

 

Back Focus Calculated for Photographical Use

Most cameras require a long back focus distance to reach focus. Newtonian telescopes have a tendency to have a too low focal plane so cameras can't be used. In our TS Line Newtonians we have intentionally used a long back focus distance so that you can easily reach focus with an SLR camera.

All telescopes are tested for their proper back focus prior to shipment.

For visual use a 2" extension tube is supplied with the telescope if needed.

Mounting Options:

A good equatorial mount is as important for a joyful observing night as is the telescope itself. All mounts have adjustable height tripods. Please note that the longer focal length versions of this telescope will need bigger and heavier mounts.

200mm Aperture TS Newtonians
200mm of aperture means 78% more light for your eyes. Some consider telescopes of this size to be among the most versatile telescopes of all. They are well-suited for visual astronomy (both of moon and the planets as well as of deep-sky objects) and are capable platforms for astronomical photography. The TS Newtonians are very lightweight and can therefore be carried by relatively light mounts.

The new 96% Hilux coatings mean that another 10% more light will reach your eyes (or your camera), making all objects brighter and more brilliant than with conventional coatings.

9-Point Flotation Mirror Cell

Despite their lightweight design the TS line Newtonians are also suitable for long exposure astro imaging. In order to achieve best results for this we have - together with Orion - developed a new mirror cell for the TS Newtonians. It is a solid yet light 9-point flotation mirror cell. The position of the nine points was optimized by a finite element software.

Advantages of the 9-Point Cell:

-- relaxed suspension of the mirror for optimized optical quality

-- nearly closed cover behind the mirror for protection

-- integrated cooling fan for quicker cooldown of the mirror

Mounting Options:

A good equatorial mount is as important for a joyful observing night as is the telescope itself. All mounts have adjustable height tripods. Please note that the longer focal length versions of this telescope will need bigger and heavier mounts than the f/4.5 version.

250mm Aperture TS Newtonians
Many amateurs hold it that "deep-sky fun" begins with 250mm telescopes. Spiral arms in many galaxies or fine structures in planetary nebulae can be seen. Of course your astrophotographical ambitions will also profit from a "fast 10-incher". In any case you will have a telescope that is still quite portable (f/5 version only) and will be carried with good stability by affordable mounts. The 10" TS Newtonian is the right instrument for those really into deep-sky or those who want to get the biggest telescope they can carry (and afford).

The new 96% Hilux coatings mean that another 10% more light will reach your eyes (or your camera), making all objects brighter and more brilliant than with conventional coatings.


Image .... TS Newtonian 250/1200mm on Celestron ADM mount - a versatile and still quite portable combination



Image ... TS Newtonian 250/1600mm on EQ-6 - suitable for photography and observing.

TS Newtonian 250/1200mm (f/4.8)

This lightweight Newtonian makes 250mm aperture portable enough for small cars. It can be carried with good stability by relatively light equatorial mounts. In our opinion this is a great alternative if you want 250mm, both visually and for photography, on a budget.

The telescope's light weight does not come at the cost of improper mechanical quality or poor workmanship. You can easily do long exposure photographs with this instrument.
Specifications:
Tube weight 8.5 kg
Tube length 1127  mm
Finder 6x30 finder
Focuser 2" with 1.25" adaptor
Diameter secondary mirror 63mm
Limiting magnitude 14.5 mag
Resolution 0.46"
Accessories Plossl 25mm / Plossl 9mm
TS Newtonian 250/1600mm (f/6.3)

If you want the best image quality you can afford in combination with a large aperture, this is the telescope for you. The telescope's long focal ratio drastically reduces aberrations like Coma, while the small secondary mirror means great contrast.

You will not suffer any problems with coma. You may even use a SLR camera without a coma corrector. What's more, planetary details are wonderful with this instrument due to its great on-axis sharpness and contrast.

Flat Mounting Block for the Tube Rings:
The tube rings are round at all points which makes adaptation of dovetail plates a bit difficult. A short dovetail plate (Vixen style) is included with the telescope.

For some mounts (EQ6, Losmandy, CGE) this dovetail plate will not fit however. Also some customers prefer a longer plate for extra stability.

For these cases we offer the "Schellenbock", a pair of mounting blocks that are screwed onto the tube rings and offer a flat mounting surface 50 x 120mm in size.

With these mounting blocks you can attach many dovetail plates easily and with good stability.

We can also cut a central thread into the blocks (M6, M8, M10, 1/4", 3/8", ...) The price for this is 10 Euros per pair.

Mounting Options:

A good equatorial mount is as important for a joyful observing night as is the telescope itself. All mounts have adjustable height tripods. Please note that the longer focal length versions of this telescope will need bigger and heavier mounts

300mm Aperture TS Newtonians
The second largest of our TS Newtonian series. 300mm (12") of aperture will offer the most fascinating and detailed views of many thousand deep-sky objects. Globular clusters are dissolved to their centre into single stars, galaxies reveal their spiral arms. Under good seeing conditions you will see details on the surface of the moon and the planets that touch the best that is possible for earthbound stargazers.

The new 96% Hilux coatings mean that another 10% more light will reach your eyes (or your camera), making all objects brighter and more brilliant than with conventional coatings.


TS Newtonian 300/1200mm on Vixen GP-D2 (shown here with the older GP-DX) on pedestal.
A surprisingly sturdy combination.
The angled finderscope is optional.

TS Newtonian 300/1200mm (f/4)

300mm of aperture on a compact equatorial mount - impossible? Not quite. I have to admit that it looks a bit curious, but due to the telescope's low weight and compact dimensions it can even be carried by the relatively light H-EQ5. Admittedly this combination is the absolute maximum of what the mount can carry and reacts strongly to wind - but it works for visual use.

With a heavier mount astronomical photography will turn out results which you had previously only dreamed of. The telescope's enormous light-gathering capacity will catch even faint astronomical objects on your film or CCD chip.
Specifications:
Tube weight 11.5 kg
Tube length 1100  mm
Finder 8x50 finder
Focuser 2" with 1.25" adaptor
Diameter secondary mirror 75mm
Limiting magnitude 15 mag
Resolution 0.38"
Accessories Plossl 25mm / Plossl 9mm
TS Newtonian 300/1600 (f/5,3)

This is the better allround telescope. It will show dramatic details on the moon and the planets. If the air is calm (good "seeing") you will be surprised what tiny and elusive details this telescope shows. Typically it will be the atmospheric conditions, not the telescope itself, that will limit the scope's performance.

Obviously this telescope is primarily made for deep-sky observations. It's huge light-gathering capacity will show faint details in galaxies and nebulae. In comparison to its shorter focal length sibling this version requires less expensive eyepieces. For photography you may not need a coma corrector at all. Please keep in mind that this telescope needs a more sturdy mount than the f/4 version.

Accessories Plossl 25mm / Plossl 9mm
TS Newtonian 350/1600mm - Aperture 350mm - Focal Length 1600mm - f4.6

A wonderful instrument for a stationary observatory. The low tube weight allows to use relatively light and affordable mounts instead of having to choose an extremely expensive mount.

The telescope is so powerful that under typical European observing conditions the telescope is not the limit to what you can see.

HILUX Coating
96% Reflective Primary and Secondary Mirrors

This TS Newtonian features the new 96% Hilux coating. The advantage is obvious: 10% more light will reach your eyes when compared to traditional coatings, making for altogether brighter and more detailed images of deep-sky objects
Optical Certificate
This TS-Line Newtonian comes with a Zygo Interferometric Test Report. The telescope is checked before shipment. Some miscollimation may of course result from the transportation (which is easy to fix by the user), but other than that you have a carefree package and do not need to worry about the quality of the product.
2" Crayford Focuser for our TS-Line Newtonians:

All Orion TS-Line Newtonians come with a good quality 2" Crayford focuser. A 1.25" adaptor is of course included so that you can use most standard accessories.

The focuser is solidly built and offers a smooth focus motion even under heavy load. Accessories are clamped smoothly but firmly with a brass compression ring... Further Information on the Focuser

 

Back Focus Calculated for Photographical Use

Most cameras require a long back focus distance to reach focus. Newtonian telescopes have a tendency to have a too low focal plane so cameras can't be used. In our TS Line Newtonians we have intentionally used a long back focus distance so that you can easily reach focus with an SLR camera.

All telescopes are tested for their proper back focus prior to shipment.

For visual use a 2" extension tube is supplied with the telescope if needed.

9-Point Flotation Mirror Cell

Despite their lightweight design the TS line Newtonians are also suitable for long exposure astro imaging. In order to achieve best results for this we have - together with Orion - developed a new mirror cell for the TS Newtonians. It is a solid yet light 9-point flotation mirror cell. The position of the nine points was optimized by a finite element software.

Advantages of the 9-Point Cell:

-- relaxed suspension of the mirror for optimized optical quality

-- nearly closed cover behind the mirror for protection

-- integrated cooling fan for quicker cooldown of the mirror

 

Flat Mounting Block for the Tube Rings:
The tube rings are round at all points which makes adaptation of dovetail plates a bit difficult. A short dovetail plate (Vixen style) is included with the telescope.

For some mounts (EQ6, Losmandy, CGE) this dovetail plate will not fit however. Also some customers prefer a longer plate for extra stability.

For these cases we offer the "Schellenbock", a pair of mounting blocks that are screwed onto the tube rings and offer a flat mounting surface 50 x 120mm in size.

With these mounting blocks you can attach many dovetail plates easily and with good stability.

We can also cut a central thread into the blocks (M6, M8, M10, 1/4", 3/8", ...) The price for this is 10 Euros per pair.
