Adaptor for Schmidt Cassegrain Telescopes:



with the Adapter TSSC-M48 you can adapt the TSOAG27 to Schmidt Cassegrain Telescopes. With this the TSOAG27 is a better alternative to the Celestron Radial Guider. The most important advantages:

-- more illuminated field because the inside diameter of the adaptor is bigger
-- shorter than the Radial Guider of Celestron
-- more flexibility, you have the M48 connection thread and the SC thread

... you find the adaptor under "Accessories"

-- To scan a bigger guide star are, the prism can be tilted by a micrometre screw - precisely and very elegant! The prism is spring-loaded to prevent any play.

-- Even heavy cameras, filter wheels etc. are carried with good stability because everything has a stiff connection to the telescope.

-- The result: You have no problems with finding a guide star and operating the guider is even possible when wearing gloves.

For which scopes is the TS OAG 2 suitable?

Because of the short design and the versatile 2" connector, this off-axis-guider can be used at nearly any telescope:

-- Newtonians... only 27mm back-focus is needed. You can attach it directly to your focuser using the M48 thread and T2 - we have the necessary adaptors.

-- Refractors... nearly any models, even with little back-focus, are possible.

-- Cassegrains and similar... the field flatteners offered for this telescopes can be combined with this guider - we can recommend individual adaptations to you.

-- CCD Kameras (ATIK, ARTEMIS etc.)... These cameras have a shorter back-focus than e.g. SLR cameras. This offers interesting combination options like:

-- TS OAG 2... combined with a coma corrector or field flattener
-- Filter wheel with T2 connection on both sides
-- Adatptation to the camera, eventually with T2 extensions for optimal distance to the corrector
