Too Cold For Outdoor Astronomy

It was even too cold this afternoon to set up my 5" refractor for use in the evening 

So I set up the Televue 85 in the living room pointing out the window.

At first, there was no point above 33x on the Moon.  As it darkened, I was able to go up to 100x before the image softened too much.  The double paned windows reminded me that they exist for thermal insulation, not optical quality.  There was a ghostly double image about 20 minutes removed the real image.

I would not attempt astrophotography from inside but at least I was able to verify that the clock drive is tracking across the sky accurately.
