About the Coronado PST Double Stack - 0.5A H-Alpha Solar Telescope...

Coronado has developed a series of Coronado Solar Telescopes as a result of the often asked question, "What is the best telescope to use with a Coronado filter?" While almost all refractors and most reflecting telescopes can be used with a Coronado H-alpha filter, no other telescope has been designed with all its optical aberrations and coatings optimized at H-Alpha. Most nighttime telescopes, when used at H-alpha, will not have the image contrast exhibited by a Coronado PST Double Stack - 0.5A H-Alpha Solar Telescope nor the image quality. Most broadband coatings, used on such telescopes, will have reduced effectiveness at this wavelength and telescopes (particularly reflectors) not specifically designed for solar viewing, will exhibit unnecessary scattering and spurious light transmission. All of the Coronado Solar Telescopes, even the PST, have been designed with this one wavelength of light in mind and will increase contrast and give you a darker background for viewing and imaging.


"Why buy a telescope that can only look at one object?" The Sun in H-A is the most dynamic object you will ever see while pointing a telescope skywards. Constantly changing and never repeating itself, the Sun through a Coronado PST Double Stack - 0.5A H-Alpha Solar Telescope will hold your attention for a lifetime. Coronado Solar Telescopes serve to enhance that view for you, your family, and friends. The telescopes provide an easy and portable set up that is always ready right out of the box.


The Coronado PST (Personal Solar Telescope)...the little scope with the BIG image...incorporates state-of-the-art patented technology to provide superb views of both Solar surface detail and prominences. Sub angstrom H-A systems have long been cost prohibitive for the amateur. Designs other than the Coronado Solar Telescope are difficult to use because of temperature and F-Ratio requirements. Not only does the Coronado PST solar telescope have a bandpass of


The Coronado PST Double Stack - 0.5A H-Alpha Solar Telescope has the same technology and quality that goes into a SolarMax series telescope, but with a few unique design characteristics that allow us to offer this Coronado Solar Telescope for less than some premium eyepieces. The Coronado Personal Solar Telescope will show you prominences, active regions, filaments, as well as other surface details. The Coronado PST telescope is made from milled aluminum, not plastic! Optional accessories include a Coronado PST Hard Carrying Case, Coronado Malta Mount, Coronado Sol Ranger Solar Finderscope and Coronado Cemax Solar Telescope Eyepieces.
