Sorry, but another one of the Sun, on 30.11.11

A clear day but hazy again. I had to take a look and found this huge prominence, and a very busy Sun, so had to take it's photograph. It was using the now usual kit of PST (must get something better, though this one is a very good one), and DMK camera on the 900GTO mount at Austerfield. A problem is that the chip I have isn't large enough to cover the whole Solar disc, so I'm looking for a focal reducer. Is there one made in 1.25"? The alternative is to extend the focal length and concentrate on smaller areas of the disc. The clouds couldn't keep away long enough for me to follow the prominence long enough to make something of it. The telescope was tuned for prominences rather than face detail. Processing done in Registax6, fine software, and Photo Shop.
