Comet 103P/Hartley 2 Update

8

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 >

Finally! Comet 103P/Hartley 2 Gets Pretty!

So I’ve been crunching all night long on this comet. And I have learned oh so much! Why are the best nights always so arduous?

First, I’ve set up RealVNC because it is so cold outside. I can’t bear to sit there and freeze! Instead I’m controlling my Windows Vista machine which captures the images from my Mac, in the nice warmth of my living room. Ahh.

Next, I’ve tried guiding on stars and stacking, like I have been doing. However, it’s finally now bright enough that with 5 second pulses 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 103P/Hartley 2 Revisited!

Comet 103P Hartley

This comet is much more fun than I had expected. October 5 and October 6 I was able to get some additional image time, in the Televue NP 101is. Unfortunately on both nights I was unable to get my autoguider to track the comet itself, so this first image is 14x 60 second exposures with the 1.5x Imaging Extender.

The second image I mixed it up a little bit: 16x 120 second exposures. The comet is beginning to show a tiny bit of a trail now. Interestingly this is less More >

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 >
