Virgo cluster with the ETX70

Another clear night after getting back from Paducah and my Legion meeting so I decided to try the Virgo cluster with my ETX. My new leveling table worked great to level the ETX and get it aligned nicely. I was able to spot the xmas tree asterism easily and could barely make out M59 and M60. M68 showed pretty well but not 89 or 90. I sketched the field around M49 and verified it as a dim patch using averted vision. I was also able to verify M84 and M86 but had them reversed for some reason or other. Both were dim in the ETX and I had to use averted vision to see them. After deciding that galaxies aren't so great in the little ETX I went hunting with unaided eye. There is a nice open cluster about 2/3 of the way along a line between the tail of the big bear and the tail of the lion. This unaided eye visible group turned out to be part of Coma Berenices (12 and 13 Com). There was a cute 'snail' asterism looking at me when I examined the area in binocs.
At 11:18 pm it was 63 deg and falling fast. R Lyra was 4.5 using 44 and 47 at 11:28. Beta Lyr was 3.2 using 32 and 38 at 11:38 pm.
Next I fired up the 'guided tour' on the ETX to see what it could do. M4 is a nice globular cluster in Scorpio near a twinkly Jewel (Antares). I could also see M4 in binocs easily. M13 is bright but small with the ETX. It looked like a fuzzy star. M6 was behind a tree at this time but I thought I could see it in binocs. This turned out to be M7 and another above it was M6. I was not able to see the ring nebula in the ETX. It might have been out of the field though.
All in all this was a great night. It was fairly warm right up to the end at midnight, clear, and NO DEW.
