3 july 2020

The night of June 29 I observed for a little while, got to 10 objects, but stopped due to poor conditions and being a bit tired.  Last night July 3 I observed for a couple hours, pointed to north/zenith, in order to keep my eyes away from all our surrounding neighbors who were having outdoor parties.  Fireworks going off in the neighborhood most of the time but trailing off at around midnight.  I could hear a lot of speeding motorcycles and cars on 880, people out for joy rides.  It's this way every July 4th weekend.

Last night had pretty good seeing, so I was able to move up to 20-inch, though with the apodizing mask.  However the nearly full moon and the thin haze cast a brightness over the sky which limited the fainter stars.  I kept myself pointed in one direction, never having to move my ladder once.  Once the moon cleared the trees I had a look at it before closing up; many craters I'm unfamiliar with since I don't view it at this phase very often.  The moon (and planets) are very low this time of year, I needed to crouch a little while standing on the ground to reach the binoviewer.
