I was outside the first time at around 2pm in the afternoon, didn't think there was much to look at except the surface, so i packed up. At 4:45pm i went out again and noticed some development. Started shooting the first AVI at 5pm

All images were recorded in double stack mode.

Stacked with Registax 6. The time lapse was batch processed in Registax 6 and the finished images were also aligned in Registax 6.


0.5x focal reducer - HDR from 3 images.


This is how fast the prom moved in just 3 minutes during my recordings.


0.5x focal reducer - 2 exposures put together.



Images with 1.5x barlow:




This is how much it moved in 1 minute and 39 seconds between my recordings.


9 minutes later.















Time lapse:

Already when i looked at the sun visually i could see how active this sunspotgroup was. Sadly i wasn't aware just how much more active that prom was. Did manage to capture some activity though.

Sequence A - 600 frames (200 stacked) were recorded every 30 seconds for 20½ minutes, in total 41 frames.
