The PST or Personal Solar Telescope from Coronado provides stunning H-Alpha viewing of the sun - you can gaze for hours on end at the active red ball; from day to day it will perpetually offer an ever-changing array of prominences, active regions, filaments, as well as other surface details.
This version of the PST is a 400mm f/10 solar viewing refractor with a 40mm objective - it differs from the original PST in that it features a second solar filter that is fitted internally. This thermally-stable system is tuned to <0.5 Å. Effectively, this PST has a doublestacked solar viewing system that will deliver outstanding views of all types of solar activities.
Operating the PST is as easy as installing the eyepiece and focusing - within seconds you're ready to gaze in wide wonderment at the beauty, enormity, and intensity of the Sun's subtle (and some not-so-subtle) intricacies.
