SUMMARY

Coronado's iconic PST 40mm f/10 0.5Å H-Alpha Personal Solar Telescope optical system is tuned to the hydrogen-alpha bandwidth with a 0.5Å (Angstrom) bandpass for viewing details of the Sun's chromosphere (surface) and prominences. A bandpass tuner allows users to compensate for Doppler shift or to highlight specific areas or zones.

It is designed and engineered to be set up quickly and used easily. The 40mm external etalon has an easy-to-use tuning ring, while the 30mm etalon primary blocking filter is set internally, so all users need do is mount the OTA on a stable platform and drop in the included 20mm eyepiece. The PST is offered here without a mount or tripod, but it is equipped with a standard 1/4"-20 tripod mount for using conventional photo/video/field tripods, or it can be mounted on many alt-az, EQ, or motorized astronomical mounts.
