Comet C/2013 A1 Siding Spring and Ptolemy's Cluster (6 October 2014)
Comet C/2013 A1 Siding spring is fading as it heads for its rendezvous with Mars. It is currently travelling through some rather spectacular parts of the tail of Scorpius.
So naturally the light of the almost full Moon is messing up imaging. Thankfully iTelescope T12, as well as being a widefield instrument that allows imaging broad vistas, is very forgiving of Moonlight.
In the full image the comet is difficult to distinguish, unlike the images back in September. The combination of fading, Moonlight and a crowded stellar field all make it a more difficult object.
Over the next few days the comet moves through some georgous skies, as the Moon gets brighter. But on the 8th, when the comet is near the Butterfly cluster (M6), there is a total Lunar Eclipse, so this will make imaging the comet and it beautiful surrounds easier.
I have a backlog of Siding Spring images to process, so you should see some nice ones shortly. I've also done some colour imaging, but I suck at that.
