TS-Optics 1,25" Solar Prism

Codice articolo: TSHE125

Fully equipped Solar Prism from Teleskop Service for solar observation and photography.

♦ 99% of the sunlight are removed, 1% are available to the observer

♦ Comes with 1.25" polarising filter for continous brightness adjustment

♦ Comes with strong narrow band green filter (interference filter) for contrast enhancement

♦ Fully enclosed housing with integrated light trap

♦ No escaping stray light, therefore especially safe

♦ 1.25" barrel at the telescope side

♦ 1.25" adapter with compression ring and a T2-thread on top at the eyepiece side

TS-Optics 1.25" Solar Prism with complete equipment for professional solar observation.

Solar prisms are intended for observing the sun with refractor telescopes. Approximately 99% of the sunnlight are removed. The rest is available to the observer or photographer. The contrast is usually significantly better than with a lens filter.

This Solar prism from TS-Optics already comes completely equipped with extensive accessories. You don´t need additional filters or adapters for observing or photography.

The advantages of the TS-Optics 1.25" Solar wedge:

♦ Particularly high-quality surfaces for very high contrast
♦ Enclosed housing with integrated light trap - no escaping stray light
♦ Cooling fins for quick removal of the heat
♦ 1.25" polarising dilter for screwing into the eyepiece or into the filter for continous adjustment of the brightness without without additional colouring.
♦ 1.25" narrow band interference filter dor significantly enhancing the contrast of the solar surface. Especially faculae regions are shown better. The filter has a bandwidth of approximately 40 nm and a peak at 540 nm. Now sun observation is possible with fast Fraunhofer refractors, as the chromatic aberration is removed.
♦ At the eyepiece side, 1.25" and T2 accessories can be attached.

For which telescopes is the solar prism suitable:

The prism can be used on refractor telescopes without built-in corrector. Please make sure that the finder is covered or dismounted, otherwise the solar energy will melt the crosshairs.

Cassegrain telescopes (SC, Maksutovs, RC, EHD, ACF) can only be used with an energy protection filter, because the secondary mirror is too close to the focal point of the primary mirror and heats up too much. The mirror could be damaged. The same applies to refractors with a built-in corrector (flat-field refractors) or tele objectives or Newtonian telescopes. Here, too, optical elements are too close to the focal plane and could be damaged. If you want to use these telescopes, an energy protection filter must be placed in front of the optics to prevent the thermal energy of the sun from entering the telescope.

Warning!

Never use the Solar wedge visually without the supplied narrowband filter (already inserted in the receptacle) and the polarizing filter. Otherwise irreparable eye damage can result!

For photographic use, however, you can use the CaK filter linked in the accessories section instead of the narrowband filter.

The narrowband filter can also be replaced visually and photographically with an ND3.0 neutral density filter if you don´t want the image to look green.
