Observing Run of 2015 NK13  on 2015-08-26 from Nerpio Spain

On 2015-08-22  I  ran a series of 45 -- 60 Second Luminance BIN2 Images on itelescope.net's (TEL T7 0.43-m f/6.8 astrograph + CCD) at AstroCamp Observatory. Nerpio, Spain  (MPC Code  I89)  and created 3 stacks of  7  images ( working stars)
