Location: San Bruno, California
These pictures were taken with the Baader Solar Film and my DMK black and white camera.
Sun granules and faculae are featured in respectively the first and second pictures
The Stellarvue SV90 (3.5″) is a fine instrument for Sun white light Astrophotography.
It reaches temperature equilibrium quite fast – and with its great optical quality it can get as far as a 3.5″ aperture can possibly go…
In addition I used a Televue x5 Powermate. Since the SV90 has a relatively short focal ratio (f/d 7) the x5 powermate is necessary to get high resolution pictures.
