Coronado Personal Solar TelescopePST 40mm aperture, dedicated Ha telescope with 20mm internal etalon. 33X Kellner eyepiece. 400mm FL. <1A bandwidth.Sub-angstrom Hydrogen Alpha systems have long cost to much. The Personal Solar Telescope (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"The Coronado design eliminates temperature and F-Ratio requirements. Not only does the PST have a bandpass of less than 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 us to offer it for less than some premium eyepieces. The PST will show 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. Product Specifications
The PST is made from machined Aluminum and comes with a built in Sol Ranger finder for easy alignment, a 12mm Kellner eyepiece, and a hard travel case with dye cut foam for safe storage. Optional accessories include a MALTA tabletop mount, CEMAX series eyepieces, and SolarMax 40 for double stacking and narrowing the bandpass. To add a SolarMax 40 you will require the T-Max 40 for attaching the unit directly to the PST.
