  • Triband-SCT's are available in apertures of 8", 9¼" and 11".
  • The telescope features:
    • Schmidt Cassegrain optical tube assembly with Triband-ERF-coated Schmidt corrector plate, rear ventilated heat shields for tube and secondary mirror (with Neodymium-magnetic holders)
    • The transmission windows are designed for Calcium-K, Continuum (incl H-beta and O III), H-alpha, S II
  • The Triband-coated Schmidt corrector plate reflects more than 90 percent of the incoming light, so that no additional ERF (energy rejection filter) is necessary
  • Highest resolution for solar observing at an affordable price
  • For the following uses, you need further equipment:
    • H-alpha: Solar Spectrum H-alpha filter, TZ-3 telecentric system and telecompressor TK0.4 or TK0.7. An additional D-ERF filter is not required. (T 630 - 680 nm)
    • CaK: Solar Spectrum CaK-filter, Baader U-filter for planetary photography in UV. (T 380 - 400 nm)
    • Continuum: Safety Cool-Ceramic Herschel wedge and suitable narrowband filters.(T 480 - 515 nm)
    • Deep-Sky (not for solar observations!):Deep-sky filters according to your field of interest (RGB / H-beta / O-III / H-alpha / S-II)

We recommend: APF-R image sharpening process

The APF-R method for sharper images was developed by Christoph Kaltseis over the last couple of years. It is based on a simple, but important question: How does a really sharp image look like? APF-R describes this step of image processing in a way.

Product Questions

Can you use a Daystar Quark instead of the Solar Spectrum with the Tribune SCT?
Question by: Robert Henry on Oct 29, 2017 3:27:00 PM | 1 Answer(s)


Size matters – even for solar observing!

There are many small, nice telescopes available which are great for a quick look at the sun in H-alpha or CaK, but who wants to observe always only with a "finderscope"? To see faint details, you need aperture and focal length. The groundbreaking Baader Triband-SCTs have got the energy rejection filter (ERF) – which is necessary for the SolarSpectrum CaK and H-alpha filters – already integrated into the Schmidt corrector plate. Especially in IR, the Triband Schmidt corrector is blocked down to 1450nm, so that the telescope will not heat up. So, you do not need an additional large and precisely polished ERF, and you can use the full optical quality of the Schmidt corrector. Additional rear-ventilated heat shields in front of tube and secondary mirror also keep the tube from heating up by the sun's radiation. This way, you can use the full resolution which is available at your location. With videography it is possible to achieve extremely high-resolution detail images of the sun. And you can do this at three wavelengths – not only in H-alpha!

The system is also great for visual observations – the sun will impress you more than ever in those moments when the seeing is good. Please note that a Triband SCT is no grab-and-go-telescope: Smaller telescope with less magnification will show nice images even at poorer seeing conditions, but a high-end telescope which pushes everything to its limits also requires a proper location. Make sure that your surroundings don't cause bad local seeing – only then you can take the telescope to its limits! The Triband-SCTs are based on Celestron's Schmidt-Cassegrains, a well-tried and reliable no-frills telescope system.

Unlike pure H-alpha-telescopes, you can use the Triband-SCT even at night: The coating is permeable for CaK, H-Beta,O-III, H-alpha and S-II, so that you can use the telescope fully for narrowband- or Ultra UHC-photography – be it with the original f/10, at night with a reducer at f/7 or even with a Hyperstar-system at f/2. You can even use UV-filters (Baader U-Venus-filter) or IR-pass-filters and achieve a surprisingly good contrast. The SC optical system suffers much less from chromatic aberration over a much broader spectral range than the best apochromatic lens telescopes. This makes the Baader-Triband-Schmidt-Cassegrains the most versatile CaK and H-alpha-telescopes on the market.
