SEWN ... back together WRONG!
I tried snapping some meteor pics last night but had no luck. I was bummed.

I've been trying my hand a star/sky photography since i finally moved to an area with a LOT less light pollution that I've lived before, but my question is, since looking at all the night sky photos/time-lapse vids, how do you shoot the Milky Way? Is there a direction you should be pointed in? Is area a factor? Does there have to be NO light pollution?

thanks for any info.

You can see the Milky Way in the first image I posted, but better in this one:

IMG_6384 by Shane Duff, on Flickr

The EXIF is still attached to the image, but the trick is to pump up your ISO (this photo was at 3200), open your aperture and use the rule of 600/focal length to determine your max time the shutter can be open before you start creating star trails. Mine is a 17mm lens, so I have about 36 seconds to work with.

The Milky Way is more visible in the fall months versus spring, at least for me in California. I'm also in an incredibly remote area with very little light pollution. I can visibly see the Milky Way after driving 10 minutes out of town.

I hope that helps, oh and of course you'll need a remote release. Or at least it makes things much easier.

Spent a couple hours at Devil's Tower a couple weeks ago, had this idea to use moonlight to light the tower (it was about 50% full that night) and get some star trails orbiting Polaris.

When all the sudden some rear end in a top hat climbers decided to descend. :argh:

So I switched modes and took time lapses of them rappelling down.



Not sure on the processing, I think it needs some attention. The screen on my macbook gets nasty banding and it makes it hard to do things right. So if anyone has suggestions I'd love to hear them.

I'd try to separate the trees from the sky a little bit. They blend together enough to be distracting. The one in the top left corner is the most problematic, so you can also just clone that one out and see how it looks.

I think the subject of someone descending is actually more interesting to me, I've never seen it before. If you crop into it, is it close enough to make out any detail of the climbers or their path?

Took my new X100 out to a festival tonight, where they float hundreds of paper lanterns down a section of river. I was shooting entirely handheld which meant ISO3200, f/2 and as steady a hand as I could muster.

I think this is my favourite shot. It looks a lot darker on my iPhone than on my computer though. I think I need to recalibrate my screen.



I'd give my left nut to retake this without slight motion blur on her face but it was a one-off shot. Oh well.





And a token urban trails shot, because. I want to find some inspiring places to shoot these in Kyoto, so there should be better to come I hope.

I tried my hand at photographing the perseids as well. Was hoping to get a great stacked image of 10+ meteors but I don't think I had the patience to stick with the same composition for ~4 hours.

these are amazing...

so, are there some kind of processing scripts you run when you're doing this stuff? is there an overview/tutorial written up somewhere? I'm still trying to figure out the best way to process my handful of photos from the Perseid meteor shower so I can stack the exposures with the ISS into a single shot. I'd love any processing advice you guys may be able to offer.

I've already got a DSLR body and an intervalometer, it'd be a ton of fun to start shooting deeper space stuff at some point but I'm not sure it'd make sense to invest in the equipment while I'm living in a big city. I wish I could find a place to rent some of this for a camping trip or something.

I use a combination of Pixinsight and Adobe lightroom to stack and process my images. Pixinsight is pretty involved, but there are some great tutorials out there on it and you can get a 45 day trial by visiting their website http://pixinsight.com/. Jekub puts out killer images using PI and I have learned quite a bit from him. In fact, he recommended it to me a long time ago. Really glad he did!


You can also give Deep Sky Stacker a shot, which is free. I know lots of folks put out great images using that software.

Are there any resources for learning more about intro astrophotography? really really curious to find out more about what the necessary equipment is to get started. shots like this are incredibly inspiring: http://www.feraphotography.com/AM14/M42.html I just always assumed it cost tens of thousands of dollars to get the gear needed to pull something like that off.

When you say your DSLR is modded is that a permanent mod or something you can revert back easily? Do you have a DSLR dedicated to this astrophotography or do you use it for everything?

There is quite a bit of discussion over in the Amateur Astronomy thread in DIY & Hobbies, lots of links to resources and discussion of kit :

The DSLR mod is to remove the IR Cut filter which cuts out a lot of the red light emitted by objects, such as the Pac-Man nebula above. This is Hydrogen-Alpha, a specific spectral line emitted by hydrogen. It's largely invisible to the human eye, and your camera blocks much of it out by default. By removing the filter we can capture these objects much easier.

In general you either replace the filter with a more permissive version, or with a clear glass filter. Both will allow the camera to autofocus as normal. Or you remove the filter entirely which causes problems. Some people also like to remove the anti-alias filter to create a completely open camera, but at that point you accept that it's never taking normal photos again.

What else is needed, like do you HAVE to have a tracking tripod, or can any average joe with a normal tripod and a filterless camera go out and try to take some pictures. Also, I live in los angeles so we can only see like 2.5 stars on any given night. Would it be stupid of me to try to get a 20d or something to take the filter out of since I can't really see any stars?

I think this might actually be mostly luck. I live in a reasonably small town in New Zealand and this photo was taken a little ways from the city centre and from brief research there has been a movement in previous years from the regional council to move towards more energy efficient street lighting like low pressure sodium lights. The lights in the foreground aren't lights from any city but are just lamps from various farmhouses. The mountain itself in the background is a national park, so a bonus of no lights coming from there at all. The other half of it is that I really put it through the wringer in terms of processing which brought on my first question on whether it looked just fake. I did it in two layers in photoshop, with the sky I tried to bring out the exposure and increase contrast to get the milky way visible and I blended it with the foreground which I adjusted on its own too. Here's one of the original frames showing Crux and the coalsack nebula straight out of the camera for reference:

there is the 20Da out there with a factory fitted filter that allows more hydrogen lines, and a new 60Da Astrophotography version, but its a bit price prohibitive.

As for gear, lets do an experiment.

There is a telescope cafe near me open on friday nights for Joes to come down and have a look. I'll take my 550D and do some test shots with a tracking and a non tracking telescope and publish the results.

For deep space long exposure photography tracking is a must, and depending on your focal length and exposure time you'll also need autoguiding to correct for mechanical and alignment errors in the mount. It's a deep and slippery slope of expense and technical frustrations that occasionally leads to a nice picture.

Don't bother taking apart a camera until you've had a chance to take a few shots and see if this is really something you want to get in to.

Frozen Pizza Party
Dec 13, 2005

I have an array of lenses for my 5D already, I guess it would mainly be just to shoot on a tripod somewhere dark. As far as getting a tracking mount I don't think I could do that any time soon, so the filterless camera would kinda be useless until that happens. And 20d's will only get cheaper.
