Hello Cloudy Nights Astrophotography Nuts,
I have a specific challenge for you! As you know, we are going to be visited by 2 comets in the next few months and I’d like to see if we can capture them all. So, from now until the end of June, I challenge all of our photographers to capture these two jewels of our solar system. Please post your entries in this thread.
NOTE: Please include the Time and Date of Photo, location and equipment used!
For a more detailed description of these comets, please visit Tim Harincar’s website: SkyRover's Comets of 2004
The following graphics are courtesy of Tim Harincar ... Thank you, Tim!
Comet Neat, C/2001Q4
Comet Linear, C/2002T7
Please note that both of these comets will be visible together on May 30th, as depicted by Tim’s graphic of what to expect:
I hope that someone is able to capture both of these together!
And as a special bonus…Comet Bradfield, C/2004 F4 will be making a limited appearance. Please visit Tim’s site for a more complete description of Comet Bradfield and you can also view a table of coordinates posted by Jason Joy in this post: Comet Bradley Discussion Thread

Going To Try shooting Q4 NEAT From Geraldton, Western Australia. Will Be Using a Nikon SLR & Kodak ISO400 film. I have planned a 3 day observing & photography session from a good Dark Sky Location. I have not as yet done much in the way of Astrophotography, So I need some Ideas on Exposure times. I will be using a 300mm Telephoto lens, & a 100x Telephoto with a 2x Converter. I have 6 Rolls to play around with on The 8th, 9th & 10th of May.

Hello Tom, I will be ready to capture these two (or three?) comets, and join this contest.But I am in Northern hemisphere so the comet's is very near to the horizon.
I had captured C2002T7 twice before with my cool ccd. One is November last year at the mag.12 one is last month about mag 6. Can I post these two image also? Of cause these two pictures is not good,because they are captured in big city

QHY2 cooled CCD camera,QHY8 cooled big ccd camera(1.8inch 6.0mp).Some new small economical ccd (ICX259AL,ICX204AL,ICX429AL)camera is under development.

QiuHY, please do.
To answer a few questions (sorry for being so tardy about this)... All of these should be visible in the northern hemisphere, even though Comet Linear will be close to the horizon, as will Comet Bradfield. Our southern hemisphere Cloudy Nighters will definitely have a better opportunity for LINEAR and Bradfield, but I have seen some amazing twilight photography from our northern hemisphere CN'ers also.
For a more detailed description of NEAT and LINEAR, please read the article on Sky and Telescope's website The Double Comet Show of 2004
NOTE: Please include the Time and Date of Photo, location and equipment used!

Thanks Tom.Today our sky become clear .I think it is the first chance for me to go out to observe. I consider to go to a dark site to try to find the comet at next morning. If I captured some picture I will let you know of post them on the board.

Tom, I wont let you down 
I just post a photo as my entry on the Q4 thread in CDD & digital.
As a hint for more challenge, I saw a guy useing a canno caught Q4's tail on a 5 minutes exposure last weekend in a star party, too bad I didn't bring my camera.

I created the graphics above to show the view from a vantage of 45 degrees NORTH (i.e. Minneapolis) - adjust accorgingly for your latitude if in the northern hemisphere.

Hey Tim, that's the same as mine. I have been meaning for weeks to ask you what latitude this was plotted for. I've noticed that other sources have not given that information when depicting a graphic view (S&T comes to mind!).
Darcy, please post any pictures in this thread as well. This is the gathering place for all photos. I hope to see it grow in the coming weeks!

And without wanting to hog the limelight, I also tried a normal telephoto.

Charles,
as soon as we get some decent weather. I intended rising early to image both Neat and Linear, but the cloud precluded this. Tonight maybe, with Eta Carina being a starter. Lotta fun this digital.

That is definitely an AM image over here and to low on the southern horizon for me to shoot. I would have to go to the Florida Keys to probably get a decent picture of it.

Hey come on, is nobody else playing this game.
Last night, again through wispy high cloud, This time with my humble wee Zeiss ED80 refractor, Nikon D100, and 3 mins exposure. It is moving quickly, so grab it while you can. Yet to see T7 in the morning sky.
Regards,
Gary

Can I post a picture here of Bradfield with Tabur?
I did not make the picture, and thus don't want to enter into the contest, more for "informational" purposes
