It was simply too cold for my Florida-behind to go out this morning, windy and freezing, so I waited until it was mid-day, seeing was terrible (for my norm). So, I went with a courser image scale and it gave me a good opportunity to use a new aperture mask that Dave made! Thanks Dave! I masked my 120mm F8.3 to 100mm F10 +/- 1mm and it worked great for getting things critically sampled where I wanted them in variable seeing conditions this afternoon (after 12pm, which is late for me!). AR2794 is pretty interesting, it's not throwing off big flares or explosions, but it has a great big faculae network around it in the photosphere, great mottling as a result in the chromosphere, and is a rather large area. There's another active area tailing right behind it that was throwing up surge prominences at the limb.
