Here's the dragon 25 minutes later. I started on Seq B right after i recorded this image.




Time lapse:

Seq A - 600 frames were recorded every 30 seconds for 15 minutes. 20% were used for final stacking for each AVI.
Used Registax6 in batch mode to align, stack and apply wavelets. VirtualDub to gather and crop the final AVI. Quicktime Player Pro to convert the AVI to quicktime.

Seq B - 600 frames were recorded every 30 seconds for 15 minutes. 20% were used for final stacking for each AVI.
Loads of clouds came drifting in as i started the reocrdings. I had to edit more than half the AVIs by cutting out parts where the clouds were too thick.
Used AviStack2 to align and stack as Registax6 couldn't do that with clouds in the recordings. Then each frame were taken into Photoshop Elements to give them roughly the same illumination.
There was plenty of action in this prom, also notice how active the area around the sunspot is.
I had to stop recording as the clouds just got thicker and thicker. Was very annoyed by that after finally catching such a fast evovling prom.
