> Taken (Thursday, Sep.19th) using my C11 HD Edge. Two 1.5 minute exposures of 
> asteroid Bamberga taken 20 minutes apart. Each exposure was given a different 
> color shift (red and cyan) so when I lined them up in Photoshop, the stars 
> were essentially white, but any moving object (such as this bright asteroid) 
> shows up as a pair of red and cyan dots because of motion during the 20 
> minute interval.

> While the asteroid itself is about 8th magnitude, the faintest stars are 
> magnitude 16.5 appx - and this on a nearly full moon night - which is pretty 
> decent.
