Based on the proven Schmidt-Cassegrain (SC) telescopes, the Triband SCs with Triband ERF-coated Schmidt plate were developed. They are the ideal basis for detailed H-alpha solar observation with a large aperture as well as for narrow-band deep sky photography.
The Baader Triband SCTs have the energy protection filter required for SolarSpectrum CaK and H-alpha filters already integrated into the Schmidt plate. The cost of an energy protection filter, which would be truly "astronomical" for apertures between 8 and 11 inches, is eliminated. Thanks to the triband coating, the telescope remains fully usable for narrow-band photography despite being designed for solar observation!
The special Triband ERF Schmidt plate of the Triband SCT has the following transmission ranges: 380 to 400 nm, 480 to 515 nm and 630 to 680 nm. In addition, it is blocked in the UV range (below 380 nm) and in the IR range (above 680 nm) to prevent both short-wave radiation and heat build-up.
Additional, rear-ventilated heat shields at the front of the tube and in front of the secondary mirror effectively reduce the absorption of radiant heat by the tube. This allows you to take full advantage of the resolution possible at your observation site.
TriBand pre-filter for narrowband observations: The transmission windows are designed for calcium K, continuum (including H-beta and O III), H-alpha, S II, similar to a UHC filter, and allow the use of additional narrowband filters.
Depending on the application, you may need additional accessories:
- H-alpha: Solar Spectrum H-alpha filter, TZ-3 telecentric and TK0.4 or TK0.7 telecompressor. A D-ERF filter is not required.
- CaK: Solar Spectrum CaK filter, K-line filter plus pre-filter for solar observation in calcium light
- Continuum: Safety Cool-Ceramic Herschel wedge and, if necessary, suitable narrow-band filters.
- Deep-Sky (not for solar observation!): Deep-Sky filters depending on the type of application (RGB / H-beta / O-III / H-alpha / S-II
