TS Optics 9mm Ultra-Short Off Axis Guider
Very low profile off Axis Guider for astro imaging. The off axis guider can be used in telescopes with a narrow back focus (e.g. Newtonians) and between an image corrector and the camera. Further Information |
TS Optics Top Performance Field Flattener
The flattener provides excellent results with almost any refractor from f/5 to f/8. Image quality is at least equal to any flattener we have compared it with. Further Information |
TS Off Axis Guider - Only 9mm Length!
|
|
![]() |
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.

TS Flat 2 - Top Performance Field Flattener for f/5 to f/8 Refractors
|
|
![]() |
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!

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. |

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.

1.25" Micro-Focuser

|
A microfocuser for all telescopes with a coarse or bad focuser. Shaky images prevent you from finding focus - with this microfocuser that problem is solved elegantly.

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

Binocular Viewers
|
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. |

BW Binoviewer
|
|
|
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. Specifications: .
The eyepiece clamp of the BW Binoviewer is precisely made to avoid misalignment.

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.
