Hi Allan;

Very nice.

Did you have to shoot two sets of exposures to capture the prominences and the disk? Or is there enough dynamic range in 16 bit mode to handle them in one image?

Thanks in advance..

Hi all,

I had a break in the clouds today and a first chance to try my new PGR Scorpion camera on the sun.

I was happy to find that I can now fit the full solar disk on the 1600x1200 chip using my 90mm Coronado filter and 92mm A-P Stowaway refractor. The seeing was poor - I did not attempt to stack frames. This image is made from two individual video frames - a bit grainy, but I like the way it turned out. A tiny active area can be seen just below and to the right of center.

Linked below the image are a couple of terrestrial shots I took with the new camera using an IR filter.

Thanks again to Tim and Milton for their help.

clear skies!

Alan
