Description:

TS 2" / T2 Flip Mirror and Off Axis Guiding System - with 360° rotation

... one of the most versatile solutions for multiple connections - for observation and imaging
... with free adjustable large side viewing port

TS Flip Mirror und Off Axis Guider
Teleskop Service has broken new ground and developed a completely new alternative to classical Flip Mirror Systems. Not only the short design but also the versatile use convinces.

Fields of use:

-- Flip Mirror:
here, no mirror is flipped but a large prism is placed onto the optical axis for 90° viewing position. In straight-through mode, the prism is pulled outward and gives the optical path free. Centre the object with the 90° viewing position, pull out the prism and capture the now centred object with your camera or observe it with a high-power eyepiece.

-- Off Axis Guider: the prism is placed at the rim of the optical field. Now the autoguider can "see" stars outside the camera's field of view. This application is recommended for sensors up to approx. 30mm diameter (APS-C). The flip mirror is rotatable by 360° making finding a guide star easy.

The TSFlip is suitable for the following telescopes:

As it only needs 35.5 mm back focus, its compatibility is by far higher than conventional flip mirror systems.
Refractor telescopes, Schmidt Cassegrains, RC and Mak telescopes can be used with the TSFlip without problems. With Newtonians, the back focus must be long enough (TSFlip itself needs 35.5 mm).

Necessary back focus for visual observation or photography with CCD cams / web cams: 75 mm
The necessary back focus is calculated by the back focus of the TSFlip itself and the length of the sideward viewing terminal. This is true for both modi (Flip Mirror or Off Axis Guider).

Necessary back focus for photography with (D)SLR cameras: min. 82 mm
The necessary back focus is calculated by the optical length of the TSFlip and the back focus of the SLR camera (35.5 mm + min. 46 mm for the SLR camera). With a classical T2 adapter, 10mm have to be added. Please have a look at our extra thin adapters shown in the accessories section.

How can I measure the back focus of my telescope?
Back focus means the "spare travel" of your focuser. Just place a standard eyepiece (without diagonal etc.) in your focuser and focus a celestial object (or one that's at least 1 km away). Then, measure the way the focuser could travel inside. That's your back focus.

That's how the TSFlip works:

TS Flipp Mirror und Off Axis Guider - Verstellbereich
A multi-coated prism guide the light by 90° out of the system. When insertet, the prism sits exactly in the middle of the optical path. So you see exactly the same object in the middle as the camera does after the prism has been pulled outside. So it's easy to centre an object for your camera or high-power eyepiece.

If the prism is pulled out partially, it can still collect off-axis light rays to be used for guiding. So you also have a fully functional Off-Axis-Guider.

Focusing the sideward terminal:

First, focus the camera or eyepiece that sits in the straight-through position. Then (without touching the telescope's focuser) focus the 90° eyepiece or camera by loosening the top screw beneath the T2 thread and slide the adapter up or down. Then, tighten the screw again. Now both eyepieces / cameras are in focus.

TSFlip connection threads:
Thanks to the popular standard threads, the TSFlip can be connected to nearly all telescopes:

TSFlip - Anschlussgewinde

Telescope side: female M48x0.75mm (2" filter thread) - 360° rotatable
Camera side: male T2 (M42x0,75) - 360° rotatable
90° terminal: male T2 (M42x0,75)

Adapter recommendations for telescope connection:
TSVF230 - for standard 2" focusers
TSSC-M48 - for SC back ends
BA2458110 - for T2 back ends

Adapter recommendations for the T2 terminals:
TST2-1-T2L - for 1¼" accessories
TST2-2 - for accessories with 2" nosepiecese
T2-CS - for cameras with C mount thread
T2-EOSs - short adaptation for Canon EOS cameras

Technical details:
-- Telescope side thread: M48x0.75mm (2" Filter thread)
-- Straight-through and 90° terminal: M42x0.75mm (T2 thread) - 360° rotatable
-- Optical length: 35.5 mm (male T2 thread not taken into account)
-- Distance from prism centre to 90° T2: 46 ... 55 mm
-- Distance from M48 thread to prism centre: 17.8 mm
-- Free aperture of 90° terminal: 16 mm
-- Free aperture of straight-through body: 38mm

The experiences of our customer Stephen Brown:

"I received my TS Flip OAG this morning. I did not expect such speedy service, my first impressions are it look great, a well made piece of equipment. I have tried it on my Skywatcher Refractor and my Celestron C8 SCT in daylight and looks like this will be a very useful tool for targeting as a flip mirror and then as tracking device in OAG mode. It has a nice large aperture on the 90 degree guiding port. I have been looking for a Off Axis Guider for a while they all have good points and bad points, the TS Flip OAG does not appear to have any bad points, I am very happy."
