Here's a wee snap of AR 798 taken yesterday, only 319 frames! This spot is one of the most intricate I've seen in a while with superb "bridges" crossing the umbra of both components. Today it has changed dramatically overnight and is growing all the time. It's a pity it's coming close to the west limb as I would love to see it in about another week from now.

Below is the unprocessed, stacked image as it came out of Registax.

Below is the final processed image after wavelet processing in Registax, removing the dust spots, de-interlace and colourize in Paint Shop Pro.

The following day I took another photo though the conditions were difficult with high winds and turbulence.
