All sales of solar gear are final. Our Take The Personal Solar Telescope (PST) is a great compact and portable Hydrogen Alpha (Ha) telescope. The internal filters block all but a very narrow band pass of light from the sun in the Ha range. This makes the scope safe to view the sun directly. It lets you see the disk and any sunspots just like a white light filter, but also allows you to see surface granularity, filaments, flares, and prominences, all of which are not visible with a white light filter. Ha scopes really give a unique "wow" factor when viewing the sun. The PST is small and lightweight enough to bring with you to any travel destinations including the upcoming Great American Eclipse on August 21st. It is light enough that it feels comfortable on a tripod or a tracker such as the Star Adventurer. It also has a built in solar finder: instead of trying to find the sun through an eyepiece, line up the telescope until the projection of the sun is visible on the top of the body of the telescope, and you know that the sun is centered and ready to view. The PST is also very easy to focus and tune to get crisp views and bring particular features of solar activity into the limelight. I've been pleasantly surprised with the resolution the PST can achieve. Overview 40mm f/10 H-alpha telescope - 400mm focal length Internal non-removable filtering optics for same solar viewing 1.0 angstrom hydrogen-alpha (Ha) bandpass Optional Personal carry case Description The Personal Solar Telescope (PST) is a Coronado innovation. The world's most popular telescope to observe the Sun. This 40mm diameter highly portable dedicated solar telescope features completely internal non-removable and student safe solar filtering optics with a 1.0 angstrom hydrogen-alpha (Ha) bandpass for great surface detail. The PST will show you the dynamic, ever changing prominences at the edge of the Sun as well as filaments and other surface details in amazing detail, all in the brilliant and distinctive red color of hydrogen-alpha light. Study of the solar disk is now within the reach of the amateur astronomer. The PST represents the same technology and quality that goes into a SolarMax series telescope available to the new solar astronomer at the cost of some single premium eyepieces. Features a 40mm diameter dedicated Ha optical system with 30mm internal etalon primary blocking filter and incorporated focuser, bandpass fine adjustment controls, built in solar viewfinder, and hard carry case. 400mm focal length, f/10 focal ratio, with Kellner 20mm eyepiece. Tripod not included. Mounting options include use on a standard photo tripod (scope is threaded for a standard camera 1/4-20 mounting bolt), use of a Coronado Malta table top tripod (sold separately) or the Meade DSM mount with computerized Autostar and GOTO technology. Open up a whole new world of astronomy with the Coronado PST.
