CORONADO  Personal Solar Telescope has a bandpass of <1.0 Angstrom, it is thermally stable and requires no more time to operate than putting in an eyepiece and adjusting the focus.

The long-awaited PST CaK version of this popular Solar-Viewing telescope has arrived at Widescreen. It is based on the hugely successful Hydrogen-alpha PST but instead isolates the Calcium K (CaK) wavelength of light.

The SolarMax40 telescope has the same aperture as the PST, but is distinguished by several key factors. The SolarMax40 telescope comes standard with a 0.7angstrom bandpass which results in increased surface detail across the disk.

SolarMax60 telescope provides the user a telescope with the same lightweight portability of the SolarMax40 telescope but the extra aperture greatly increases the resolution of detail on the surface and on the limb of the Sun. With over twice the surface area of the SolarMax40 telescope the difference is obvious.

The SolarMax70 is a version of the 1st Coronado H-Alpha telescope, Helios I, with technological improvements. All the telescopes in this line (Helios I, NearStar, SolarMax) feature a unique design with an etalon smaller than to be less than the SolarMax 60. The design creates a bandpass of 0.8 angstroms which is slightly higher than the standard for other SolarMax series telescopes.

The SolarMax90 is the largest Ha telescope ever to be mass-produced. Noted for incredibly sharp, ‘contrasty' H-Alpha views, and stunning detail. Even when viewing with a single eyepiece the sun appears fully animated even revealing hints of curvature, this effect is enhanced when used with bino-viewers.
