SolarMax Ca-K 90mm Telescope
In order to complement our line of Hydrogen Alpha filters we are, for the first time, offering the Sun in a new light! This model telescope is based on our popular SolarMax 90 telescope design and its mechanical functions remain largely the same. However, we have developed a filter system for this unique instrument that allows for the standard production of a Coronado Calcium K telescope.
This instrument focuses on the transmission line of CaK centered at 393.4 nanometers. The thermally stable interference filters allow you to view the chromospheric network of ionized calcium emissions that are created when supergranualtion cells sweep through magnetic fields where they collect and strengthen. This emission line will not be visible by eye to all observers and the primary use of the SolarMax 90 CaK telescope is for imaging. What you will capture with this new instrument are plage, active regions, and magnetic storms in a layer of ionized calcium gas that appears in a violet/blue hue. This layer of gas is a cooler and lower level of the Chromosphere than one observes thru our H-Alpha filters and provides new information on solar activity and weather.
As with all Coronado products you can be assured of safety, quality, value and superior performance. This new telescope has the exact dimensions and mechanical performance as our SolarMax 90 telescope in H-Alpha. Binoviewers are unlikely to work with the telescope at this time and the SolarMax 90 CaK has been designed with imaging as its primary purpose. CCD, DSLR, and most digital formats will be compatible with the SolarMax 70 CaK. Some will require adaptors that Coronado does not provide but are the same as ones used for night time imaging.
