Comet tracking
Originally uploaded by MPR Photography-PhotoMPR.com
This weekend I enjoyed two nights under very dark sky at a private observatory of a family friend.
One of the goals of the nights was to see the approcahing comet. It was in Cassiopia near "ET".
I first spotted it with my celestron 20x80 binoculars. Then to the 10"
Dobsonian. It was clearly visible with both. I looked it around 8:30pm then started starhopping around. Then went back to it at 9:45 movement through star feild was noticable. So I decided to sketch it but all I had on hand was post-it notes and a pen, not the best.
I made 2 sketches: one @ 9:55pm the another at 11:25pm. I then overlaid the two post it notes and was able to measure the amount it moved and created a scale to predict it's movement in 1 and a half hour increments. The result is below:
