Treats for the Brain

October 31st, 2007 by Chris

I took inspiration from the Bad Astronomer’s Halloween plans and set up my telescope right in the front yard. The viewing was pretty poor, what with all the front lights on, but it was worth it for every “Oh cool!” from every kid who saw the comet tonight.

If even one of those kids goes home and puts “telescope” on their Christmas list… score.

Unfortunately, the viewing wasn’t ideal with some high level clouds rolling in (it’s now completely overcast). I did get a couple more comet shots. Based on my limited data it appears to be fading pretty fast now. I took a shot at approximately the same setting as the last two (sorry, I keep forgetting to double check the aperture setting), and adjusted it to get it in the right ballpark.

I also took one with the ISO cranked up to 1600. This is approximately the full resolution image (it’s a little too large to fit in the post width):
