[AZ-Observing] Re: Saturn was good tonight

I was out on Monday night and Saturn was very good. At 200x I had to wait to
get steady seeing, but it was there, including good banding detail on the
planet itself.. I would love an observatory. I had been planning one and had
come home Monday from the building inspector. They wanted more details on
the rolloff roof. I threw the plans away after Monday night. The new Lexus
dealers lights went on. This new dealership, still under construction less
than 1/4 away , lit up the NNE sky to the top of the big dipper. Despite
proper lighting. the shear wattage just overwhelms. And all that light is
just reflecting off the ground. Just imagine what it will be like after
there are cars there.I can't wait for the new Cadillac dealership to open
next door. Of course all the other dealership are already here. I now have
overwhelming sky glow from Polaris to just west of the southern meridian.
Add in trees, a streetlight out front, neighbors unshielded 24 hour security
lights, upward looking spot lights on landscaping and I think I could read
the newspaper outback. Brian Skiff, if you made it this far, is there a easy
method for measuring light pollution with a digital or CCD camera?

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.
