Shameless plug: more astronomy - DPChallenge Forums

Hi all,

Two more shots. I spent a night in the northwoods of Wisconsin where it's REALLY dark. Shot another milky way shot:

And for fun, put the camera on a stationary tripod aimed at Polaris, and set the remote timer to snap a 20 second exposure every 2 minutes. I put the resulting 20 images into an animated GIF. Instead of star trails, I shot a circumpolar movie. Link is below. Bandwidth warning, the animated GIF is 2.6 meg in size so be patient while the whole thing loads:

Very cool. Whereabouts in Wisconsin was this?

Left a comment. Is this kind of shot hard to do? Could a 300D do it?

MK: Chequamagon forest, about 30 miles south of Ashland (about 6 hours straight north of Madison)

Odyssey: Yes, a 300d could do this easily, but you'd need a telescope that has a tracking motor to mount your camera to. This cancels out the earth's rotation so the stars don't trail and the milky way can saturate.

Neat. I'm headed up to Hayward next week which looks to be about 30 miles south of where you were. But I have no telescope. :(

That is so cool. I love the animated shots. Someday (I hope), I will be able to afford a big boy camera and try some of those shots. Till then, I will just admire others. Thanks for sharing!!

Kind of a amature astronomer my self. Love the shot added it to my favs.
Did you use an Eq mount?

Thanks for the Fav Fibre. And to other commenters, yes, it was on an equatorial mounted, my telescope, with a drive to compensate for earth's rotation. Here are a few other shots from my portfolio.

Hee hee, I posted this in the other thread, but it was a thread killer. Maybe it will do better here...

This was taken in central Wisconsin with a Canon 15mm fisheye lens and a standard tripod (no tracking). Six exposures were combined. A larger version is here, (clicking "original" will bring up the largest size).

Nice Job especially with no tracking.
I wish it was dark enough at nights around here to try this. There is a street light everywhere here unless I drive 30 minutes to get to the country.

Would shooting near a street light destroy the shot?

I was wondering, has anyone shot with the 20Da? The 20D for astrophotography that has a weaker IR filter and some other enhancements specifically for astrophotography?

They are very bright here. With the eye I may see 1% of the stars you see in kirbic photo because of the light. If the sky clears tonight I may try it and see.

Superb shot Fritz, considering you had to work without a tracking mount. My Peleng fisheye should be here any day now. What about the GTG we've been planning??
