Sun Spots today

This is, I think, my best solar image so far. It's not very good, but it's my best in terms of solar detail...

Captured with the ToUcam through the PST, 3x barlow lens and UV/IR filter. I still struggle with focus, and the scope is on a fixed tripod (I need to come up with a simple tracking solution for it!). There are many artifacts in the image, the lines sloping down from right to left are the direction of drift across the CCD. Some of the others are wavelet induced.

Image was stacked R4 (that was fun in itself). Processing in PS CS3 included levels, curves, B&W colourisation and save for the web.


I'll have a play with some of the un-waveletted files after I get back from picking up the kids...
