More comet

Filed under: — stan @ 6:26 am

I snapped a few more pictures of Comet Holmes last night. It’s a bit dimmer now. The first picture is a 10-second exposure on ISO 400. I finally figured out how to set the camera for long shutter times. Compare the second picture today with the second picture yesterday. Both are 1-second exposures on ISO 800. They look pretty similar, but for some reason, it looked a lot dimmer to the eye.

Just for the record, the telescope was a Celestron C-8 with a 32mm eyepiece, giving about 60x. The photos were all cropped and then scaled down by a factor of 1.9, so they are all showing the same size field. The camera is a Canon A560, and most importantly, it was attached to the telescope with Scotch® brand packing tape.
