Sun Spots AR 2312, AR 2310, and AR 2305

Some Sun spot close ups with a new ASI120MM. I bought a second hand 120MM to use exclusively for solar imaging, so the IR block and Solar Continuum filters can remain permanently fitted, leaving the other camera on the filter wheel. I have also permanently fitted the cooler to this camera.

I was wondering whether the IR block filter was as good as it should be, so today added a second IR block to the filter stack. While seeing was deteriorating during the session, I have still managed some nice detail. Both images are from the 200PDS scope, and the first image is at the native 1 metre focal length. The second is at 2 metres. Video runs weren't very long due to lots of passing clouds - 24-03-15
