imaged the Saturn Nebula (Halifax)

The BGO robot imaged NGC 7009 for me. The planetary nebula in Aquarius. Also know as the Saturn Nebula, as well as Caldwell 55. One of the RASC Finest NGCs. Hints of the "rings."

The imaging run was halted and I only received luminance, red, and green photographs. The error message said it was likely due to clouds; I suspect it was the Sun.
