11th October 2012 AstroPhoMo (Astro Photo Month)

Had another go today imaging the sun this time with the DSI Colour CCD.  After consulting an Ice in Space thread from last year discussing CCD imaging with a Coranado PST, I got a better feel for exposure times and how to use a laptop screen outside in the day (i.e. put a tarp or blanket over you and the screen).   Consequently I've spent a good part of the afternoon under the blue tarp that usually covers my telescope when I'm not using it.

The image is made of 10 x 1/250 sec frames with flats.   As the subject matter is so bright all the smudges and dust on the ccd show up too.  The flat basically subtracts these out of the final picture.
