You'll see a plane (the red line) and at least 3 satellites in this image.

Paul, the president of the Fraser Valley Astronomy Society pointing to Jupiter with his green laser. With that big telescope of his, I was able to see the big band of clouds on Jupiter, and at least five of its moons....it was epic.

Oh, if you're wondering about the red light, it's because red light does not ruin your night vision. Using flashlights with white light, or any blue component will cause you to lose your night vision and then you'll have to wait a few minutes for it to come back. You'll also piss off everyone around you.

I was using a 5DMKII with a 15mm fisheye and the 24mm f1.4 for the most part.

Yeah, but it's gonna be a lot colder! The Geminids Meteor Shower will be on December 13 & 14, and on the night of December 21, there will be a total lunar eclipse. On October 20, Comet Hartley 2 will be 11 million miles from Earth, so it will be visible to the naked eye if you're away from the city glow.

For sure, but the air will be more crisp, and clear. The chances of a clear sky decreases, so who knows how it would turn out. A little cold doesn't hurt :p Especially now that I got some CF legs :D

Oh, and for all the people that want to shoot the next meteor shower, Popular Photography made an article for it. It's published in their newsletter

See the differences? Good. :p
These (and others I took) were taken at 6300ft, at Wedgemount Lake, 12km + 7km hiking up 5000+ feet to get to the lake. All taken last night. I forgot to take my remote shutter release with me, unfortunately, so couldn't do longer bulb exposures. :(

Senna, in your last picture, is that Jupiter up at the top? I'm curious how you got the stars to trail in a circle like that as well :)

08-15-2010, 08:15 PM
^ the earth is rotating during the long exposure which makes the stars make those circle lines.

I think it's Jupiter, but I can't be sure. The telescope was pointed at and was tracking Jupiter, so it very well may be. I just put my camera on the telescope and pointed it perpendicular to where the telescope was pointing.

That's a really neat picture Hyper!
Thanks Senna :) The guys I was with were pointing out various objects in the sky (one of them was using a star map program from his phone) but I missed half of them because I ended up getting dizzy turning in circles trying to see all the meteors lol.

Any suggestions guys on shooting stars? The other night, a group of friends and I were in the middle of the sea to sky highway at a viewpoint. I tried taking some shots of the stars, but ended up getting a lot noise even at ISO 400. It the type of noise that I would associate with an image that is underexposed.
Would you recommend me bumping the ISO to 800? I was attempting for just a shot of the stars, without trails.

I was shooting 30 seconds, f2 or f2.8 @ 800 ISO. Exposures longer than 30 seconds will show trails.

If anyone wants to join me, I'm going up on one of the weekends. It will depend on weather and the forest fire situation though. I've managed to borrow a GPS star tracker to mount the Canon 500mm f4! W00t!

It's time to upgrade my camera. I took these using bulb, and even then, the camera would only let me open the shutter for 90sec tops. As a result, super tough to get the camera still.

What's the best camera for taking star photos? Something FF like the 5Dm2?
Soundy

Aperture wide open, and you can go several seconds without noticeable star trails... even up to a minute, you should only see a very slight stretching of them.

If you want still stars and you're using a high resolution camera, you wouldn't want to go past 30 seconds, as trails are noticeable at 100%. Of course this will all depend on how big the final images will be - my shots look fine on the web, but at 100% you can see trails.
The best DLSR for astrophotography is any DSLR with the low-pass filter removed. For stock DSLR's, Canon used to make cameras specifically for astrophotography like the 20Da, 30Da, but they have been discontinued. Currently, Canon DSLR's seem to be the cameras to use, as Nikons process the RAW files on the sensor (Sony sensors, remember) resulting in unwanted noise.

My images were so dark because of the lack of any ambient city light, etc. and the fact that they were all taken at approx midnight at 6300ft elevation. They were 30 second exposures at f2.8 ISO800.
Full size, you can see the trails, smaller/on the web, the trails are less noticeable/not noticeable.
One thing that I did notice, it being so dark, was that I had a hot-pixel which I've since remapped.
