Padraig,

Very nicely done. I just hope it stays where it is and away from us :-)

Subject: [AZ-Observing] Bamberga - another photo




> 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.
