More about the series PST...
The 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-alpha 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?
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 telescopes and filters but it certainly doesn?t disappoint.

It is not only important which telescope you buy, but also where you buy it.
We provide extra help:
- We are a leading telescope dealer and know these instruments like the back of our hands.
- We are always very happy to offer our assistance after your purchase, should you encounter any problems with your telescope’s setup or operation.
- Our ‘Telescope Basics’ booklet - an 80-page beginner's guide for our telescopes – is provided free of charge with every telescope we sell.
Our expert comment:
The PST has been designed with a short focus path, meaning cameras cannot be focused. A Barlow lens can be employed to lengthen the focus. Unfortunately, not every Barlow works. In practice, the Hyperion Barlow, product number 23745 has proven itself. The Hyperion Barlow allows you to achieve sharp focus with DSLRs, DMKs and webcams.
