Description

I shooted Messier 13 last night in order to test a very short focal autoguider. The sky was really so so, i picked seven exposures, two minutes each for each filter (RGB only, no luminance). So, there is a 42 minutes total exosure for this globular cluster. 20 to 30% of the images are shooted through particularly thick clouds...
