Astronomy pictures of the day

Possibly some bad news for astronomic photography, thanks to Elon Musk (link):
Most optical telescopes (ground or space based) have a field of view of about the full Moon, so one [ed: of the Elon Musk satellites] will be crossing the field of view every ~10 minutes. 30-90 minute exposures are the norm, so it's going to be impossible to make an observation without one ruining the exposure.
