Comets Lovejoy and Linear X1 
in the morning sky
January 26, 2014

 This morning was completely clear, a day after a very cloud filled Saturday. I was up at 4am and set out to image at least one comet, Comet Lovejoy - now making its leisurely pace across Hercules and very low on the eastern horizon an hour before morning twilight. Up till now, it has been below the wall of the observatory in Payson, and with the LQ moon now getting out of the way we can image comets again. This was the first opportunity to capture this comet again in the 12.5" f/5 astrograph!

Between 5am and 6am I was able to get both L channel and RGB data on this 7th magnitude object. After 6 I was finished and thought that comet Linear X1 now around 9th magnitude which was less than 10 degrees away would be possible in the start of the morning twilight. The digital circles on the mount were not behaving well, and I kept getting the field next to the comet, with no comet in sight. Finally at 6:25 I got on the comet but the autoguider would not track on such a bright blue sky. So I managed a single guided 60 second shot before the guider failed tracking. Not a very deep shot, but its not too bad considering!

All shots are with the water cooled ST10xme CCD at -20C and AstroDon filters. The field here is just under half a degree...
