From an aristocratic family Danish astronomer work without the telescope,Tycho Brahe, in discussion of his work, after disagreements with the new king in 1597,develop his own theories of astronomy, the natural hunting occupation of astronomy, made an important discovery, with accurate measurements of the sky spotted a shining intensely being perceived in the constellation of Cassiopeia without a telescope.Galileo was one of the first astronomers to use a telescope.

Best Enjoyed Viewed Large on Black
This is from after a sunset drive out to the Pawnee National Grasslands in northeastern Colorado. Any major cites are a good 35 or more miles away, but the light pollution is still fairly strong. The light pollution certainly made for an interesting sky show here with some patterns in the sky I've not photographed before (see the almost inverted red rainbow lips looking glow?).
It's pretty amazing to think in roughly 24 minutes that the Earth rotates as much as the star trails indicate here. This was made even more amazing to me as I waited an equal amount of time for two jets to get out of the frame before I pressed the shutter, heh. ;-)
Shot notes: I felt like a break from stacking for the heck of it, so this is all one 24 minute exposure. I truly lucked out and no more jets came across the frame for the entire exposure at f/5.0 and 500 ISO on my Tokina 11-16. LENR was on. The gaps on the reflected star trails are odd, I think they were caused from when it got windy for a bit.

This pit, and it's twin, were used to observe the heavens. People could walk in between the long, raised portions. The twin is the exact reverse set up, just meters away.

I give up, I'm just going to post this one. I've been playing with this one for a while. The strange color banding in the lower right corner is from a nearby street light.

Venus has passed from behind the sun (superior conjunction) and is slowly moving into its greatest eastern elongation phase. It will become exceptionally bright and should be spectacular in the clear skies that frequent this area of the country.
Should look fantastic with the sunsets we have here.
