Details:
Asteroid 357439 (2004 BL86) imaged on 26 Jan 2015 at 1519UTC, from Singapore city.
Meade LX-90 8" SCT f/10 (2000mm fl) fork-mounted. Canon EOS 60D, ISO 3200, 15 seconds, cropped.
In the image, the asteroid appears to be wobbling. If correct, does it mean that it is wobbling in its orbit, and therefore irregularly shaped and a fast rotator? Or is it only an imaging artefact?
This wobbling appears in all my images of this asteroid. Note: the telescope was not tracked on the asteroid, only a specific RA & Dec coordinate.
