Sky Conditions: Fairly Poor - Bright Moon/Heavy Moisture

Its been a while since the skies were clear enough to do any real astronomy work - this has been a terrible year for astronomy.  But even with the bright moon out tonight, I'm giving it a try.  I decided that since the sky is heavily polluted with moon light, I would just try for a couple brighter objects to see how things will go since it's been so long since I've been able to turn the scope on.  The first one I went for was NEO 190491 2000 FJ10 at magnitude 17.0.  As usual, using MPO Connections, the scope slewed right to it and I only had to do a minor correction to get the asteroid centered up in the frame.  This object was moving at 6.60"/min at an P.A. of 121.7 and at that speed I limited the exposure times to 60 seconds to prevent any trailing of the objects and to prevent gathering too much light pollution from the moon.  Even with the bright moon the object showed very well in the images - see observations and image below.

I also imaged NEO 53319 1999 JM8 since it was in the area and was listed by the Minor Planet Center as "Observations Desirable" between Oct. 19th and Nov. 18th.  This object was at magnitude 17.1 and moving at a slow rate of 1.00"/min with a P.A. of 253.9.  Still, I kept the exposures down to 60 seconds and stacked them in groups of two to do the measurements of the object.  See observations and image below.

The Sandia All Sky Camera also picked up a few meteors tonight.  The information on those detections can be found here.  There's also an image of a brighter meteor along with video below.
