Seriously Ceres

First clear night after a wet week in the LRGV so I decided to see what I could see. Ceres has been hanging out in Leo so I took a look. First problem: it wasn't in the list of asteroids in CdC. I used ephemeris elements from the skychart user's group and added it to the data file. Bingo, right on target. I found it by slewing to one of the stars in Leo that was in the catalog. Next I held 'mode' down for a few seconds to put the controller in RA/DEC display mode and just slewed manually until I got it to the position shown in CdC. There it was, right in the center of the FOV. The star field matched CdC to a 'T'. 40 Lmi was the brightest star in the field, with a small triangular grouping of three 8th magnitude stars just below Ceres. Three other 7th magnitude stars were 'above', 'below', and to the right of Ceres near the edge of my 27mm EP. Ceres seemed to be about 7th mag. NGC3344 was in the FOV but way too dim for my ETX-70. I was just able to make out M81 in UMa later on.
It was warm and a bit muggy at 61. Ceres was high in the east near zenith and unfortunately I set my scope up where a street light shone right into my eyes. Not a very good position!
