Observing Run of 164202 (2004 EW)  on  2015-07-03

On 2015-07-02 I  ran two series of 45 -- 15 Second Luminance BIN2 Images on itelescope.net's (TEL T32 0.43-m f/6.8 astrograph + CCD)   at Siding Spring Observatory, Coonabarabran, NSW, Australia. (MPC Q62) and created 6 stacks of 15 images.

The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15.

The Asteroid (387733) 2003 GS during the total lunar eclipse of 2014-04-15. The idea was to take advantage of the total lunar eclipse get useful images of a "desirable" NEO. The moon position was within 25 degrees from the imaging target ((387733) 2003 GS).... if this was a "normal" full moon It would have mostly likely been too "close" to get "good" Images.
