About this image

I had done a simple set up to see if i could image Calcium-K with My DSLR but i didn't like the results. With the sky being hazy i thought nothing would be wasted. The sky then improved so i got the DMK31 camera out and captured this image. I was on an altazimuth mount and had to hand guide to follow the Sun.
