Deep Sky

I went out for a little deep sky photography Thursday night, and it's really cool. I used a deep sky imager (DSI) which is like a digital camera censor chip that hooks directly into where the telescope eyepiece normally sits. It sees a lot more than your eye, and transmits that image to your computer which records the snapshots. This photo is relatively boring, and not real "deep" into the sky. Until you realize that each dot is a sun, likely long dead and collapsed upon itself only to release photons of light that we see. A star cluster is a bunch of these and I am trying to get a good shot. This is M13 (Messier catalog objects, FYI) of the constellation Hercules. Just dots, until you think about it. I'll try to get a better one this weekend.
