I was wondering if anyone was out tonight or will go tomorrow...
Would you share your best shots and maybe a bit about the shoot?
Thanks!

When I heard about the Perseid meteor shower I decided early on that I wanted to try and shoot it from the summit of Mount Evans in Arapaho National Forest. I mainly do long exposure star trails, but I thought I'd try some shorter-exposure high-ISO work with the 5D3 to get "frozen" stars with a meteor streak in the the shot. That requires a lot of luck, I know, but I set out none the less with this goal in mind.
I spent most of yesterday getting my gear ready, charging batteries, testing speedlights, getting the color gels laid out that I would use, etc. I even got my cold weather gear out since I knew the summit would be chilly.
The clear sky charts were questionable, but a clearing was indicated between 1am - 4am, so I thought I'd go for it. I set out early, around 9:30pm, and I'm glad I did. The base of Mount Evans is about an hour from Denver, and then there's the summit road to drive. I forgot how dicey that summit road is, and in the middle of the night, the sheer drop-offs make for quite a white knuckle drive. I think the 14-mile summit access road took me an hour alone.
When I got to the top, I immediately started setting up my gear and taking some shots. The sky was clear, and I didn't want to waste it. Good thing too - because within about 40 minutes heavy clouds rolled in and the rest of the night was a bust. The shot below is my favorite of about only 12 photos I took last night. This is by far the fewest number of photos I've ever taken given the amount of preparation and driving I did.
Even with only one good photo to show for my efforts, it was well worth it....

While shooting with my 30D yesterday night at Iso 800 I just made up my mind to go definitely for a 5D3. Moonless or small crescent moon nightsky shots don't produce very usable material at these Isos. Especially if you aim for the Milky Way. As I really like to take these pictures, I kinda feel the limits gearwise. Which are the highest ISO you shoot at? 3200, 6400 or higher? Thanks for any hints. Cheers, Peter

Thanks, Pedro, Victor and Brett!
This was really the first time I had attempted to do "frozen" stars with my 5D3. I've done them on my 7D with an f/2.8 Tokina lens at lower ISOs with some decent results. But the fastest lens I have for my 5D3 is my 17-40 f/4L. Being limited to f4 on the widest end, I really had to push the ISO up to 6400 with a 30 second exposure. 30 seconds is about as long as you can go at 17mm before you start seeing star movement. Even on this image, at original size, you can see the stars slightly blurred from the earth's rotation. Even with this reduced size version, you can still see some movement blur on the stars in the far right of the frame.
So to answer your question, the ISO 6400 leaves a little to be desired from a noise/potential-print standpoint, although it's workable with heavy NR in post. If I were to do this again I'd rent an f/2.8 lens, so I could drop a few stops in ISO and get a cleaner result.
On a side note, I started doing astrophotography on my 40D. As long as you stay below ISO 400, and don't mind star trails, you'll get results plenty clean enough for printing from your 30D!
Nice, I like the colour of the meteor, you don't see too many of these. A method to improve your odds is of course to take many short exposures sequentially. There should be about 1 meteor per minute (for the whole sky), so it shouldn't take too long to capture one in your field of view, on average only a few minutes total exposure time.justsomedude said:I mainly do long exposure star trails, but I thought I'd try some shorter-exposure high-ISO work with the 5D3 to get "frozen" stars with a meteor streak in the the shot.
