The PST from Coronado. This ‘little’ telescope is another step toward Coronado's goal of making it possible for everyone to “Experience the Sun our way". The ever changing solar disk presents iself in the PST with tunable views of prominences and surface detail previously unavailable at even 3 times the cost. Sub angstrom H-A systems have long been cost prohibitive for the amateur. Designs other than the Coronado are difficult to use because of temperature and F-Ratio requirements. Not only does the PST have a bandpass of 1.0 angstrom but it is also thermally stable and requires no more time to operate than putting in a eyepiece and adjusting the focus

The PST represents the same technology and quality that goes into a SolarMax series telescope but with a few unique design characteristics that allow it to be offered at less than some premium eyepieces. The PST will show you prominences, active regions, filaments, as well as other surface details – at 1.0 angstrom it will not reveal as much surface detail as the SolarMax series telescope and filters but it certainly doesn’t disappoint.

The SolarMax 40 telescope has the same aperture as the P.S.T. but is distinguished by several key factors. The SolarMax 40 telescope comes standard with a 0.7angstrom bandpass which results in increased surface detail across the disk. A T-Max attached directly behind the etalon gives you the ability to adjust for Doppler shifted light. Bino-viewers and most imaging equipment will come to focus, sometimes with the use of a Barlow or OCS. These features plus enhanced surface detail make the SolarMax 40 telescope a more versatile instrument with remarkable solar images.

With the SolarMax 40 telescope you will see all of the limb detail of the P.S.T. but with enhanced surface features. The SolarMax 40 telescope comes standard with a BF5 blocking filter but a BF10 version is also available and recommended for use with imaging equipment and bino-viewers. The larger blocking filter allows you to extend the focal length without vignetting but does not enhance detail or lower the bandpass. You can also purchase a second SolarMax 40 filter / T-Max, along with a small adaptor plate, and attach these to the front in order to lower the bandpass to 0.5 angstroms. This is called ‘double stacking’ and further enhances surface detail.

The SolarMax 40 telescope comes standard with a clamshell mounting ring and hard travel case.

For those looking for more aperture Coronado proudly present the SolarMax 60 dedicated H-alpha telescope. Built to our exacting standards the SolarMax 60 telescope provides the user a telescope with the same lightweight portability of our SolarMax 40 telescope but the extra aperture greatly increases the resolution of detail on the surface and on the limb. With over twice the surface area of the SolarMax 40 telescope the difference is obvious.

The SolarMax 60 telescope comes standard at 0.7 Angstroms with a BF10 and is available with an internal module to lower that to 0.5 Angstroms. A T-Max attached directly behind the etalon gives you the ability to adjust for Doppler shifted light. Bino-viewers and most imaging equipment will come to focus, sometimes with the use of a Barlow or OCS. The advantage of the extra aperture becomes clear each time you view.

Included with every SolarMax 60 telescope are the travel case, 25mm CEMAX eyepiece, and clamshell mounting system.
