The sky was quite hazy in Houston in the early mourning hours of July 6th.
However it was also very steady and I can't really complain since a couple
of hundred miles west of here 25 inchs of rain has fallen in the last few
days. The image data is below:
Taken with a C14 @ f/27 with a ST5c from Houston Texas July 6th at 10:01 UT.
L=15 x 8 sec
R=G=B= 3 x 10 sec
Uranus is about 3.8 arc seconds and the moons range in brightness from about
13.8 to 14.8 magnitude.
