I agree with Steve. Last night was a great night for observing. Even
mild temperatures. I got several hours worth of UBV photometry and J
& H band photometry done. Monday night was good also. I feel bad for
those who can only observe on weekends.It seems the weekends have
been less than great recently, but many weekday nights have been
really wonderful.
While many discount observing in the Phoenix area due to the light
pollution, the merits of a backyard observatory are well worth the
effort to do just that. While many deep sky objects are not available
(at least easily) from the Phoenix area, there is still a lifetime of
wonderful objects you can observe from your backyard. Being able to
just hop out back, do your observing and then come back in for TV,
bed or whatever is really great. Driving for hours to a dark sky area
only to find poor observing conditions has got to get old fast.
