Description
Alpine Astronomical HERSCH-PII Overview
The Baader Cool-Ceramic Safety Herschel Solar Photographic Prism Mark II from Alpine Astronomical provides safe full-aperture solar views without image degradation. It features an integrated rotation mechanism for polarizing filters, the best method for brightness adjustment in visual solar observation, and solar photography in white light. This filter rotation mechanism allows filters to be rotated steplessly in the optical path. Since the Herschel prism emits single polarized light, a stepless brightness adjustment is made possible in combination with the optional Baader Single Polarizing Filter 2" (#2408342) and the included Neutral Density Filter. All necessary filters always remain in the Herschel prism, even when changing eyepieces. The prism comes with the Baader 7.5nm Solar Continuum Filter 2" (540nm) (#2961581) with 7.5 nm half-band-width for an uncompromisingly sharp solar image.
Every Herschel wedge needs additional neutral density filters since the reflected energy of the first surface prism (4.6%) still is a factor of 1000 too large for the human eye. All Baader solar diagonals are delivered with a pre-mounted ND 3.0 Baader precision 2" light reduction filter. The photographic version also includes ND 0.6, 0.9, 1.8, and 3.0 filters for selective light attenuation when using cameras and high magnifications.
- One-sided Phantom Group antireflective coating, with ceramic solar finder and 2" ClickLock eyepiece holder
- Integrated rotation mechanism for polarizing filters�the best method for brightness adjustment in visual solar observation and solar photography in white light
- Stepless brightness adjustment is made possible in combination with the optional Baader Single Polarizing Filter 2" (#2408342) and the included neutral density filter (the polarizing filters are not included)
- Baader 7.5nm Solar Continuum Filter 2" (540nm) (#2961581) with 7.5nm half-bandwidth
- S58 dovetail and safety kerfs on the 2" nosepiece
- 3-point adjustment system preset in the factory
- Sturdy IP67-rated transport case made of ABS plastic
- Space technology: A multiple staggered light trap made of heat protection sheets and heat-absorbing special ceramics as the end of the light trap absorbs the radiant heat without heating the surroundings too much; the prism also remains temperature-stable for a long time
- Enclosed housing: No risk of glare or fire from the emitted sunlight; observation is possible without danger
- Solar finder: The ceramic plate also acts as a screen for the sunlight beam. Aiming the telescope at the sun becomes very easy
- ClickLock clamp: With 15° rotation, you clamp every eyepiece securely, even in winter with heavy gloves
- Short overall length: Shortening the overall length by 30mm for the use of DSLR or Binoviewers with optional T-2 adapter Diamond Steeltrack T-2 Adapter (#2957202) or Diamond Steeltrack M48 Adapter (#2957204)
- Filter holder: On the rotatable filter holder, all necessary filters are firmly installed in the housing�no danger when changing eyepieces
