The Sun 21-7-08 AR1000 filament activity

Imaging between 17.40 and 18.18 BST. The seeing was absolutely horrendous with the surface and limb turning to wobbly jelly on occasions and plenty of thin wispy cloud passing over. I thought video imaging would be a waste of time but how wrong can you be! The DMK's capabilities truly are remarkable at 60fps. Out of each run of 2000 frames I was getting only 30 or less to stack at 95% quality threshold. Even so the images were more than acceptable and the surface shots clearly showed detail in the active region. Prom shots were more tricky and only one of these turned out OK. AR1000 was very dynamic with tiny areas of occasional brightening and fast moving AR filaments. Some nice larger filaments nearby too.
