Observation Log 2/22/04

2/22/04 9:30-11:10 pm: Used Celestron 25mm eyepiece, leveled tripod, set Goto to +/+, ended aligns w/Down & Right buttons. I chose Polaris & Rigel (opposite ends of sky). I used de-focussed rings to ease centering. GoTo performance spot-on for Saturn, Jupiter, & … Ceres!! Showed Saturn to Jan w/15mm, 9mm eyepieces. She liked it!

To do: for Jan, learn good filters for planets, show her Jupiter. Also figure out how to center at high power & keep tracking on & accurate. Question- does tracking stop after a goto RA/Dec? How to restore it? This was a problem for Ceres. Is it backlash?
