The TS Optics Off Axis Guider is the lowest profile OAG that we currently know and offers many unique features.

- Extremely easy to use: Separate focusing mechanism for the guiding turret, scanning function for searching a guide star, three available positions for the main camera.

- Ultra-low profile: You can use the Off Axis Guider on telescopes with a very narrow back focus (e.g. on Newtonians). The guider can even be used between an image corrector and the camera!

- Compatible with almost any camera: The TS OAG9 can be used with DSLR cameras as well as CCD cameras. Even large format CCD cameras can be used!

- Large clear aperture: The TSOAG9 is available with a direct M48 adaptation and thus has a much larger clear aperture than possible with a T2 adaptation.

The TS Flat 2 is a very high quality, top performance field flattener that works with almost any refractor telescope. It has been tested and approved for many refractors from f/5 to f/8.

In all refractors we tested it with the results with the TS Flattener were at least equal to, and typically much better than any other flattener we have compared it with, including the flatteners recommended by the respective telescope manufacturers.

With its special layout the TS Flattener allows for the use of filter supports, off axis guiders and similar accessories between the camera and the flattener. This offers a previously unheard-of flexibility of use!

For a few quick impressions of the image quality please see below!

Sample Image: NGC 6992 on a TMB 105/650 APO with TS Field Flattener

The following images are magnified sub-frames of a full APS format (Canon EOS) frame. They are shown at 300% of the original resolution. The left image shows where the sub-frame is located on the original image.

The image was taken on a 72/400mm ED refractor without flattener, with the original flattener recommended by the refractor manufacturer, and with the TS Field Flattener.

You can clearly see that the TS Field Flattener offers by far the best image quality!


Image without field flattener. The stars are elongated. Even at 50% resolution this will still be clearly visible. This is the typical impression with almost any refractor and it demonstrates why field flatteners are so important!	Image with the officially recommended field flattener offered by the manufacturer of the refractor. The image quality is better than without field flattener, but stars are still distorted. This effect is also visible at the regular 100% resolution.	Image with the TS Field Flattener. Stars are pinpoints out to the edge of the field of view. Even at very close inspection (remember that this is 300% resolution!) no distortion of the stars' image can be seen.

TS Optics Laser Collimator TS LA

The TS Laser Collimator - the thumbscrew to the right is the on-off switch.

Newtonian Laser Collimator - 1.25" Barrel Diameter

A well made all metal laser collimator machined from 40mm massive aluminium.

Mechanical Quality
Since the Laser pointer itself has a very thin wall and is quite delicate the massive body of the Laser Collimator serves as protectice cover.

Barrel
The Newtonian laser collimator has a long 1.25" barrel and a machined rim for proper alignment. These very relevant parts of the laser's function are CNC machined.

Chesire Collimation Eyepiece


Chesire - with precisely machined rim

View through the Chesire collimation eyepiece in a Newtonian - you can see the slight miscollimation.	View of a slightly miscollimated refractor. Both rings should be centered.

Chesire Collimation Eyepiece 1.25"

The Chesire collimation eyepiece is the classical tool for Newtonian and refractor collimation. Light is reflected into the telescope through the 45° angled surface. When looking through the small porthole of the Chesire you will see the separate optical components and the reflections thereon. A perfectly aligned telescope will have all reflections centered around each other.

A crosshair at the front end of the Chesire helps to know where the center is.

The Chesire has a broad rim that is precisely machined so that it will sit in the focuser in perfect alignment - if this were not the case collimation would be imprecise.

For a refractor alignment is just as easy. You will see one reflection for each glass-to-air surface. If the telescope is perfectly aligned all reflections will be centered - in general such a perfect collimation is not necessary, though. It is enough if the reflections are inside one another, they need not be centered.

FOC 125 R with 1.25" barrel

1.25" Micro-Focuser - Non-rotating!

A very helpful addition to your telescope for planetary imaging and for observers who only have a quite coarse focus mechanism on their telescope.

- non rotating
- the microfocuser has a locking screw
- very fine focus motion. One entire 360° turn only moves the eyepiece or camera by 10mm
- with the integrated T2 male thread at the eyepiece side you can use all kinds of photographic adaptations.

Specifications:

Telescope Adaptation	1.25", 2", Vixen M36.4 male or T2 female
Eyepiece Adaptation	1.25" + T2 male thread
Shortest Length	47mm
Focus Travel	10mm

This focuser is also a very interesting and low-profile focuser for a self-made planetary Newtonian or a compact travel scope.

Observing with both eyes means a significant gain in your eyes' ability to see faint details. At the same time you will be more relaxed and can observe for longer periods without straining your eyes. Binocular viewing is helpful both for lunar, planetary and deep sky observing.

A nice side effect is that negative effects of seeing conditions do no affect the image as much. When watching with both eyes objects seem larger than with only one eye.

The light is split 50/50 for each eye. Despite that you will not notice a loss in image brightness - the human brain is able to add the images seen with both eyes and even see more detail than would be possible with one eye.

BW Binoviewer - full view

The BW Binoviewer - one of the most popular high quality binoviewers we know.

BW Binoviewer

The new BW Binoviewer was designed for astronomical use from the start - this is not just a revamped microscope binoviewer. It has large prisms and is blackened inside for best possible transmission and suppression of reflections.

The compact body makes the binoviewer comfortable to use.

This binoviewer is in our opinion not comparable with the new Chinese made binoviewers in terms of optical and mechanical quality.

1.25" ronchi eyepiece - full view

1.25" Ronchi Eyepiece - A Tool For Testing Telescope Optics

The Ronchi Eyepiece is used like a normal eyepiece. It is inserted into the 1.25" clamp of your telescope and then "focused" with the focuser. The only difference is that you look at the image from both sides of the focus.

You will see several "bars" that describe the surface of the optics. Theoretically perfect optics (even though we haven't seen such optics before) have perfectly straight ronchi lines. The lines can be curved, distorted, ..., always hinting to various different optical aberrations.

Warning: While it is easy for everyone to see optical aberrations with the Ronchi eyepiece a lot of experience is required to judge how strong those aberrations are.

The Ronchi eyepiece has 10 lines per mm.

High Quality Transport Cases from StarWay

Starway transport cases protect your expensive and delicate optical equipment ideally. The cases are specifically made for particular instruments and thus fit the telescope perfectly.

For this reason we order each case for you specifically. This results in a slightly longer delivery time, but this way you can make sure that you get the best possible product to suit your needs!

A particular hard foam was chosen to protect the telescope from impacts and to avoid scratching the tube while at the same time offering best possible rigidity and a long lifespan.


The cases are kept shut using robust buckles. The buckles have locks for safety.	Several of the cases have rollers for easier transportation. All cases have handles.	The foam of each case (except models for self adaptation) is individually cut out for each telescope model.

Starway case with a Celestron CGE inside

Specifications:
- robust aluminium cases with reinforced edges
- individually cut-out foam available for many different telescopes or mounts
- hard foam for ideal protection and a long life-span
- several of the cases have rollers for easier transportation
- robust buckles keep the cases securely shut. They have locks for safety.
- excellent protection from mechanical shock as well as against moisture.

Scope of Delivery:
Each case has foam inside. The foam is either without cut-outs for self-adaptation or has cut-outs for a particular instrument.

A few more Examples:
