Lunar or Siderial Tracking for Saturday's Moon-Venus Conjunction
drgert1
Hello All,
On Saturday the cirrus clouds prevented deepsky CCD imaging in the Bay Area. However I wanted to make use of the occasion and so I ended up taking pictures with the Canon DSLR of the nice conjunction of the Moon and Venus in the evening sky. For the photos I used a Tak 4" F8 APO and AP0.67x focal reducer. This put the conjunction nicely into the frame of the Canon RebelXT DSLR. Interesting to note that I tried both siderial and lunar tracking for the longer exposure shots of the sequence. The long one at the end of the sequence is 15sec. After comparison I decided that it's more annoying to have dozens of tiny trailed stars that an ever so slightly smeared moon. So I ended up using the siderial tracking shot for the sequence on the web page. I had a lucky shot witht he airplane crossing the moon, too. http://www.trivalleystargazers.org/gert/moon_venus_20070519/moon_venus_20070519.\; html Enjoy, Gert
