Coronado PST - Personal Solar Telescope 1A Bandwidth
Coronado PST - Personal Solar TelescopeThe PST is the latest innovation from Coronado. This "little" telescope is another step toward our goal of making it possible for everyone to "experience the Sun our way." 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. And did we mention the price of just $499.00? The PST represents the same technology and quality that goes into a SolarMax series telescope but with a few unique design characteristics that allow us to offer it for 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. "To be honest I wasn't expecting much when I set this scope up late in the afternoon. Alignment was a breeze with the built-in sun finder. As I looked through the eyepiece I could see a red sun with a small sunspot but no prominences or H-A detail. I then decided to try the "tuner" and as I rotated the ring the view changed and prominences popped into view! With a little further tweaking filaments faculae and "orange peel" surface came into view in incredible detail! Absolutely brilliant."- Mr. N. Longshaw U.K. The PST is made from milled aluminium not plastic! The P.S.T. comes with a built in Sol Ranger for easy alignment a 20mm Kellner eyepiece and a re-usable box with dye cut foam for safe storage. Optional accessories include a hard travel case MALTA tabletop mount CEMAX series eyepieces and SolarMax 40 for double stacking and narrowing the bandpass. To add a SolarMax 40 you will need the T-Max 40 for attaching the unit directly to the PST."I purchased a PST a couple of months ago. After reading some comments on adding the SolarMax 40 I purchased one and attached it to the PST. There is only one word to describe the view. WOW - Keep up the good work!!!" - Mr. Rankin Florida.Product SpecificationsDesign Parameters of Coronado PST 1) Optical:Objective focal length 400 mmClear Aperture 40 mmWavelength of Operation 656.3 nm (H-alpha)Nominal Spectral Bandwidth of Operation <1.0ABlocking Efficiency 10?5 Internal optical re-focusing mechanism provides compatibility with most conventional eyepiece lenses.Built in Sun finder fully multi-coated doubletbottom thread 1/4-20 for standard fit to any photographic tripod2) Mechanical:Advantage: telescope body does not have moving or extending parts.
