Three frames taken today with one hour spacing between images. The sunspot activity has come clearer into view and with the extended time lapse can be seen rotating clockwise. Whether this is due to the Sun's rotation or our relative position I'm not sure.
I have now managed to fit the whole disk in frame with my Meade DSX90-AT by removing part of the T64 adapter thereby moving camera position closer to scope by around 50mm giving better image scale.
details : Meade DSX90-AT Maksutov Cassegrain, Canon 350D with Meade T64 adapter, Baader Solar film - home made filter, all images 1/200th sec @ iso 100.
