Coronado PST - CaK - Personal Solar Telescope Calcium K - NEW!
The Coronado P.S.T. CaK is a truly remarkable telescope linking two of Coronado's most recent technological breakthroughs. By combining the optical design of the price friendly P.S.T. with the Calcium K line filters of our SolarMax 70 CaK we are again making solar discovery a real and attainable aspect of Astronomy. At $599.00 you the amateur astronomer will be able to image a layer of the sun that very few have ever seen.The unique CaK filter isolates a layer of the Sun that is below and slightly cooler than the layer viewed with a Coronado Hydrogen Alpha filter. The transmission line is centered at 393.4 nanometers and is isolated using thermally stable interference filters. Given that this telescope has a much smaller aperture than its bigger brother the SolarMax 70 CaK you can anticipate a drop in resolution but not in contrast safety or quality. The magnificent super granulation cells that gather and strengthen in this layer of the Chromosphere may not be visible to all as most humans eyes through the process of aging are not particularly sensitive to this wavelength. The primary purpose of any CaK instrument is for imaging.Coronado does not guarantee the performance of any imaging equipment being used in a prime focus position. All equipment will work in an afocal setup using the appropriate adaptors. These are the same adaptors that you use at night and at this time are not offered by Coronado. If your current imaging equipment will not work at prime focus and can't be used in a afocal setup Coronado recommends the purchase of one of the Meade Electronic Eyepiece systems. The Deep Space Imager or the Lunar Planetary Imager. A computer is required to operate these. The P.S.T. CaK will work with the Malta Mount and features a built in finder scope.Product SpecificationsAperture: 40mmF/L: 400mmF/Ratio: F/10Bandwidth: Max 2.2?Thermal Stability: 0.005 ?/CBlocking: Full blocking >105 from EUV to far IR
