This is a composite of two exposures, a short 1/13s second shot to record the disk detail, and a long 1/2 second shot to record the limb prominences. There were three very large prominences this day. This was taken with the little Sony DSC-V1 (2003 vintage) point and shoot camera and a Scopetronix 40mm eyepiece and and afocal adapter, looking into the little Coronado PST H-alpha solar scope, undriven. A DSLR would be better but does not reach focus with the PST scope. It is tough to focus the stack so it is a bit of a guess. A crude system but in a pinch it does work.
