Comet Lovejoy, first attempt

After a long time without any opportunity to observe anything, and a few updates my relevant software, I finally have the opportunity to take care of this year’s blockbuster comet. The new house has a roof garden, and I have a tripod and a camera.

There it is…

The comet is about 1/3rd the way between the Pleïades and the horizon. That is too finicky for me, so I use a wide-angle approach. After a test shot going with 10 seconds exposure at ISO 100 with a fully open iris, I see nothing. So, up to ISO 800. That should do it for the comet but I still don’t see much. So, ISO 1600 and 15 seconds. Since I’m only using a tripod (with the current storm gusts I’m not going to put up a ‘scope mount!) I already get elliptical stars, but at least the comet becomes visible.

I am hoping the weather report holds true with a clear sky on Saturday—I’ll be out in the fields with the big rig!
