Sigma 70-200mm f/2.8 EX DG HSM II

How is it that you can get such a good result with a single shot? Here's my (lame) attempt from last night using DSS for the first time:

I was quite chuffed with it until I saw your shot. I guess a number of factors - better lense, better camera, less light pollution. Anyway, I'm not disheartened yet. I'll give it another go tonight with a lot more shots than lst night.

Think F/2.8 and the 6400 ISO was a key in that one.
I usually do long exposures at night with wider lenses to help show the landscape, but the sky gets pretty lit up from the light pollution. I've never been able to pick out a nebula with those settings and it washes out what little bit of the Milky Way I can see here. I need to take that 70-200 out more often at night.

ISO: 1600
Focal Length: 18.0mm (18-55 kit lens)
Aperture: f/4.0
Exposure Time: 30.000 s

You're going to have a tough time getting a good M42 with the nearly full moon sitting practically on top of it. Wait a week or two, and you'll have much better results.

True, there is that. Plus I'm going out when Orion is quite low to the south right over my house and the street which is quite brightly lit. So many considerations!

Here's my first attempt at the Orion Nebula. Not too bad for the middle of a fairly large city and the moon nearly full. Though, I think I need to work on my post processing.

Shot with my Sigma 70-200 2.8. I'll be headed to darker skies in a couple weeks, hoping for even better pictures then!

Anyone have other ideas of cool things to shoot in the sky without a tracking tripod or telescope?

If you can get to a darker site, there's the Andromeda galaxy. If you get a long enough exposure, you can capture two of its satellite galaxies, and if you frame to the right side, you can get the Whirlpool galaxy also.

Right now, you can get lots of star clusters. There's the Pleiades, and the Perseus Double Cluster, for starters.

Single exposure tracked with an AstroTrac. The final result should look better after I stack the 6 individual frames. Camera used is a modified Canon XSi with Astronomik CLS-CCD clip-in filter. Lens is a Zeiss Planar 50mm f/1.4 for EOS.

Awesome shots, never realized the Horsehead Nebula was so big!

How long was that exposure on Barnard's loop?

Those are both impressive shots VisualUniverse. I love the composition (?) of the mountain and Orion.
It's also a good endorsement of the lens if that's a full frame with it wide open.

Thanks. It is an f/1.4 lens and I shot at f/2.2. When shooting stars, it is normal practice to stop down a bit from wide-open.
