It's About Time.

Comet C/2001 L4 PANNSTARRS has finally graced our northern hemisphere skies. This evening for me was a little frustrating. Located below a new moon it should have been visible. Except there was a horizon of cloud that stayed put for the duration. It was good to see via facebook a couple of fellow bloggers and Breckland AS society members, Dr Dan Barnfield Bob catch a glimpse of the comet this evening.The skies however have cleared. The seeing not perfect but I have set the cameras in motion. Having done very little astronomy since christmas it feels good to get back to it. I had planned on a slight modification to my set up in which the 66mm guidescope would come off and used as a grab and go. My imaging scope would then be connected to an off axis guider and camera, thus lightening the load on my ageing mount. But unfortunatly the focusser just could not take the weight for the auto focus to work. So I have gave up on the idea and rebuilt the 66mm back on board. I have also increased the counterweight slightly and this seems to help with the guiding consistency. With this I wanted an easy target to test the system. I caught about 90 mins will process in the morning.

As promised from last night I managed to capture some photons of that were travelling through the darkness of space for 35 million years to arrive last night at my camera lens. This trio of galaxies all look slightly different as the galactic discs are tilted to different angles from our line of sight.The galaxy on the left is known as NGC 3628, seen edge on with obscuring dust lanes cutting across the plane of the galaxy. while the disks of M65(top) and M66 are both inclined enough to show off their spiral structure. There is evidence that all 3 galaxies have interacted with each other some 800 million years ago.
