Art, the Pacman Nebula (ionized by O type stars), isn't yellow!!!
Nuh-uh!!!
But Jaime Fernandez sure got his colors beautifully right... like this color for Comet Hartley 2!

Re: Comet Hartley 2
I used to play pac-man on an Arcade machine when it first came out. It was FUN!, but TANK was loads of fun because you got to fire little dots at the other guy's tank.
But I'm wondering what Owlice's Moving Through Space post is showing. MY updated IE8 won't show me unless i start clicking on a lot of things. It seems to have set somthing off. I get a 'blocker' notice even opening up a posting window in this forum.
And how come I'm seeing red squares in the left hand corner of the last 3 or 4 posts to a thread all of a sudden? And then they may disappear the next time i look.

Re: Comet Hartley 2
beyond, the Moving Through Space post has a couple of images of the comet, one of which is a movie which shows the comet in motion (so is way cool!). Try Firefox rather than IE 8, perhaps?

Comet 103P/Hartley on oct 1st
Hi!
Here is my first picture of this comet, from Can Duran Observatory, in Palamos, Catalonia (Spain). I could only take 50 minutes, clouds didn't forgive!

Re: Comet Hartley 2
I finally got to see owlice's comet movie. It turns out that i had to go get 'Quick Time' from Apple to see it. Wheeeeee! i got to see it move a whole inch!!
And i don't get the pop-up restricter warnings any more. YEA!

I took this on Sunday morning 10/3. It is a composite of 10x5mins. It gives a sense on how quickly it moves in a 50 minute time frame.

Re: Comet Hartley 2
According to CCDCalculator the FOV is 45x67.7 arc minutes. It was taken with an AT8RC and Orion Starshoot Pro DSCI.bystander wrote:What size is the field of view?
Re: Comet Hartley 2
Owlice, are you going to be able to give us more comet movies later? I want to see if it hits or misses the bigger brighter object that it looks like it's heading for.

Icy Visitor from Beyond

Hubble Probes Comet 103P/Hartley 2This visitor from deep space, seen here by NASA's Wide-field Infrared Survey Explorer, or WISE, is comet Hartley 2 -- the destination for NASA's EPOXI mission.
The comet, known officially as 103P/Hartley was discovered fairly recently, in 1986, by Malcolm Hartley in Siding Spring, Australia. It probably originated from an icy orbit close to that of Jupiter's, before something knocked it on a path toward the sun. The comet circles the sun every 6.46 years -- its upcoming closest approach to the sun, called perihelion, will take place on Oct. 28, 2011. EPOXI, which utilizes the already "in flight" Deep Impact flyby spacecraft, will reach the comet on Nov. 4.

The fuzzy background in this picture is noise, primarily from dust in our own solar system. Stars cannot be seen because they are subtracted out during the process of averaging multiple WISE pictures together into this one view.
Infrared light of 4.6, 12 and 22 microns is colored blue, green and red, respectively.
WISE Captures Key Image Of Comet Mission’s Destination
Credit: NASA/ESA/H. Weaver (JHU/APL)
Hubble Space Telescope observations of comet 103P/Hartley 2, taken on September 25, are helping in the planning for a November 4 flyby of the comet by the Deep Impact eXtended Investigation (DIXI) on NASA's EPOXI spacecraft.
Analysis of the new Hubble data shows that the nucleus has a diameter of approximately 0.93 miles (1.5 kilometers), which is consistent with previous estimates.
The comet is in a highly active state as it approaches the Sun. The Hubble data show that the coma is remarkably uniform, with no evidence for the types of outgassing jets seen from most "Jupiter Family" comets, of which Hartley 2 is a member.
At the time of the Hubble observation, the comet was 1.153 astronomical units (172 million km or 107 million miles) from the Sun. The comet was 0.218 astronomical units (32.6 million km or 20.2 million miles) from Earth.

Re: Comet Hartley 2
Are only 5 frames of 3 minutes from sunday evening and can be seen clearly accelerated motion in our solar system.
No big deal, I made it with a telescope SC8 "and a Canon 5D, very improvised.
And a picture with a processor, which give priority to the stars, then make another one where I will give priority to the comet:

Hi,
in the night from 8th to 9th October 2010
comet 103P/Hartley 2 met the famous double cluster h/chi Persei.
Unfortunately the air was very humid but I could manage to capture some frames
of this spectacular meeting.
The final image is a composite. First, tracking was on the comet causing long star trails.
Second tracking was on the double cluster.
Location: Remseck / Germany, balcony observatory
Date: 8th to 9th October 2010
Scope: TEC 140, focal legth 980mm
Camera: FLI ML 16803-65
Mount: 10micron GM2000
Total exposure: 2 h
Processing: MaxIm DL, Photoshop CS3
Hope, you will like the image.
Regards
