After some learning I’ve finally been able to image a comet through my main 9.25″ SCT telescope! I was helped of course by the fact that Comet C/2014 Q2 Lovejoy is unexpectedly bright, so much so that it is visible with the naked eye in a dark sky, even next to the mostly full moon. The whole world is watching as the comet grows brighter by the day and should peak around Jan 19th. The comet was discovered by prolific comet hunter – Terry Lovejoy, an Australian astronomer from Queensland.
The green colour comes from the icy water vapour the comet ejects into space. This comet will not be back for 8000 years.
