Using a Coronado SM60 + BF15 + ToUcam II (modified B&W chip) + Baader Fluorite Flatfield Corrector on a TMB 115 f/7 refractor, I made this animated GIF showing changes in the vicinity of a sunspot in a 1 hour period. The animation consists of 14 images taken at 4 minutes interval. The ToUcam avi files were recorded in K3CCD, registered and stacked in Registax V3 and further processed in Photoshop and ImageReady. The frames are reduced in size by about 75 %. The animated GIF is 1400 kB, give it some time to load completely.

This time I made the mistake to forget to take a flatfieldimage, so the dark/gray round speckles you see jumping around are from dust on the CCD!
