Coronado PST hydrogen-alpha solarscope
Coronado PST ready to use...
My brand new Coronado PST hydrogen-alpha solarscope in it´s carrying case. The narrowband filter within the Coronado solarscope isolates a specific bandwidth of light called hydrogen-alpha. This allows to view the Sun´s cromosphere. Prominences, filaments, active regions, plages, sunspots and flares are all able to see by this solarscope.
Some specs:
Aperture - 40 mm
Focal length - 400 mm
F/ratio - F/10
Bandwidth - < 1.0 Å
Thermal stability - 0,005Å/C
