20060723 Full disc H-alpha solar

Aperture blocked, I guess only 30mm used:

Tmax is not adjusted but left in closed position without tilting, the hotspot is reduced.

Other notes:

On trying to locate the sun, I tried to project the sun on the wall and it does so without problem, it also shows that part of the aperture is blocked and by how much.
