Summer back log part 3 - Messier 13

I mistakenly had the cooling on the ccd shut off and forgot to turn it back on, as such I didn't have any matching darks to kill the hot pixels.  However, you can see that even 32x30s (16min) are enough to bring out well over 2,000 stars and many more that DSS couldn't count.  I was happy with the framing only AFTER I found NGC 6207.  Even still, I now see PGC2085077 at mag 16.15 and even fainter ones, 3501406 and 4507623 at mag 19++
