Went out on the balcony for some observing last night at around 1:30am. I star hopped along Virgo to find the M5 globular cluster. It is rather large and bright, but unfortunately I think my 1.3 sec exposure caused star trails because M5 is close to the celestial equator and so appears to be moving faster.

This cluster brings my Messier Object total up to 64 out of 110. 

I also observed Saturn through my Meade 285 refractor and 6mm eyepiece. I could clearly see the rings, but could not identify the Cassini Division.
