Hi Trevor,
A grand image, but can I ask why is the edge of the sun not a smooth circular shape/edge ?

Thats you told Dave! 
Just wondering though, is that an animated Gif or am I going mad. I could swear those prominences are moving!!

Oops, I forgot to check back
It's really more down the camera I think. When trying to capture the proms I use a much slower shutter speed to get them bright enough, that has the effect of making the brighter part of the prom at the bottom burnout along with the disc. I guess using something like Skynyx with it's higher dynamic range could help with that but I suspect that it would still occur.
Cool, I'm not the only one then
Seriously though, one of the fascinating things when looking through a solar scope is how dynamic these things are. The proms can look different hour by hour. Really cool stuff.
