I did some more experimenting with the solar seeing monitor with the firecapture plugin on Friday. However despite this clever and powerful piece of software if the seeing is just not there then it simply isn't possible to pull good data from it. The graph below shows this well; from 10am it was cloudy until about 10.25am, and the yellow line on the graph wiggling away shows the transparency was variable with the high cloud and haze passing through. The seeing was variable though jumping up and down in the unstable air and wasn't really suitable for the larger apertures as this soft image of granulation taken with the the Daystar Sodium Quark and Airylab HaT shows. Camera was the PGR IMX249.
