The (not very) dark night sky.

So we are near the new moon and I had what I thought were clear skies tonight.  No time like the present to stab a camera on the tripod to see what I could see.

It took a few frames to realize that I have far more light spill/pollution in my area than I suspected.  I was expecting to use an exposure like 30 seconds at ƒ2.8 and ISO 3200.  That was waaay too bright.  Thirty seconds at ƒ4 and ISO 640 was plenty.  Only three stops of light and change, no biggie.  Note to self: you have to go somewhere much darker than here to get the good stuff.

Anyhow, here is a useable frame from the experiment.  The tree on the right is an oak I planted way back in the day, which is now about 80 feet tall.
