Coronado 0.5 Angstrom Personal Solar Telescope (PST)

The world's most popular telescope for observing the Sun. This 40mm diameter highly portable dedicated solar telescope features a superior 0.5 Angstrom bandpass for increased surface detail. 

Using the P.S.T., you can view the dynamic, ever-changing prominences at the edge of the Sun as well as filaments and other surface details, all in the brilliant and distinctive red colour of hydrogen-alpha (Ha) light.

Features an easy-to-use built-in solar viewfinder, a 40mm diameter dedicated Ha optical system with 40mm external tunable etalon, 30mm internal Etalon primary blocking filter and incorporated focuser and bandpass fine adjustment controls, 400mm focal length, f/10 focal ratio, with 18mm plössl eyepiece. Mounting options include use on a regular photo tripod (scope is threaded for a standard camera 1/4-20 mounting bolt). An optional Vixen-style dovetail is available separately to make it simpler to fit into a standard Astronomy mount saddle.

Please note the Coronado PST is designed primarily for visual use. The focus position is approx 5-10mm above the eyepiece holder. Some CMOS cameras with minimal back-focus will work, and some, like the ZWO ASI120 Mini, fit nicely in the eyepiece holder.

Mounting a DSLR camera is more of a challenge because the sensor is set deep inside the camera body. Still, it is possible using a Baader Hyperion series eyepiece with an adapter.

Review of the double stack PST
22 May 2022  | 

Although i didn't get my DS PST from First Light Optics, i can confirm this scope is excellent ( as my image that can be seen above shows). It shows a wealth of detail with stunning high contrast for imaging and visual use. The difference between the single stack PST and DS PST is simply outstanding and the single stack PST is a cracker of a scope as well. I have used first light optics for a lot of my astro gear and have had excellent service and products from them, this DS PST will be among those products
