Friday Comet Update


Comet Holmes was surprisingly difficult to see Friday evening (and Saturday too). It has dimmed slightly from mag 2.9 to mag 3.1, but that brightness is also being spread out over a larger area, so the "surface brightness" is a lot less.

The moon is getting bright too, which is probably making it harder to spot the comet. It was even pretty dim in binoculars on Saturday evening.

The bottom line is that the comet doesn't jump out and smack you in the eyeballs like it did just a few days ago, but it is still well worth checking out.

It still photographs well, as you can see in this shot from Friday night. This is a stack of four 4second exposures at F2.8 and ISO1600. It looks like I got the focus better on this one than the one from November 10.
Here is a link to the post from Nov. 1 as well, if you want to see a wide angle view and get a feel for how the comet has been moving with respect to the stars.
