Comet 103p/Hartley 2

Comet 103P/Hartley 2 Update


We’ve been under a spate of poor sky conditions, yet two days ago there were clear enough skies to take a few images. Even if they didn’t turn out near as pretty, I still learned a bit in the process!

Using the CPC 1100 and 30 second unguided exposures, I stacked these using “comet mode” in DeepSkyStacker. Apparently the first time I tried this I didn’t read the manual very well. This time around I found out how to “click the comet” for stacking even when the comet is not detected as a star More >

Comet 103p/Hartley 2 – October 13 2010


Well, tonight seemed like it would be a good night although wow it’s getting cold out there fast. And lots of dew, too. My astrozap dew shield was pretty much dripping wet. Gross!

Tonight I decided to image with the CPC 1100, f/6.3 reducer — and to mix it up, I decided to 2×2 bin with the StarShoot Pro. Pulling in 60s unguided exposures yielded pretty nice subs (well, half of them passed my test). I also left the Skyglow filter on, although I don’t know that’s really useful for cometary More >

Comet 103/P Hartley

More Comet 103P/Hartley!


Comet 103P/Hartley was moving right near Casseopeia this past week. Since the crown “W” shape of this constellation is easy to spot, that makes it easy to also find Comet 103P/Hartley.

Luckily I was able to get two nights to image this comet a bit more. However, before imaging, I also spent some time observing with a 20mm eyepiece in the CPC 1100. 103P/Hartley appeared very diffuse and the halo was very small, yet unmistakably visible.

Comet 103P Hartley 2


Comet 103P Hartley, discovered in 1986 has been receiving a bit of attention lately. NASA’s Deep Impact space probe will be making a visit in early November. However, riding around magnitude 7, 103P Hartley is now easily visible through binoculars and telescopes.

I thought this would make for an interesting imaging target. But first, how to find it? Well, Bill Rogers over at Cloudynights was kind enough to put a post with Stellarium scripts for locating this comet. One these are stuffed More >
