K3CCD_0007Large solar prom from the 23rd March 2011. My first time taking the wee 40mm PST out in ages so seeing proms this large was a nice surprise.

For my sins I used the Astrotrak and it took AGES to get everything aligned perfectly; the image was taken at f25 so every slight movement caused a large jump at the viewfinder. Next time I’ll use the asgt when imaging, just for sanity’s sake. Still it’s impressive that the wee astrotrak could do this and it is still great for visual solar observing.

About 1300 frames in registax and then processed in PS.

PST with mono toucam on an Astrotrak tt320x.

Think this is big though. Have a look at shots from the 20th on Spaceweather here.
