Capturing the Milky Way

[Rocco]

Anyone know of any good resources or even posts on this site about the different techniques of capturing the milky way? It seems the search function is down at this moment and I usually like to do some research before posting a question.


Thanks,





Rocco

Hey Rocco...I'm not sure about technique, but I do know it takes a really good lens at infinity, and it helps to have a fast one , too. Here are a couple examples I took while in Yosemite. Actually they were taken at my Dad's second house in Pine Mountain Lake, near Yosemite. All taken with 1D4 and my new Zeiss 35 1.4 @1.4...


Big dipper, at 25 sec, @iso 200

and my favorite with shooting star..30sec ISO 200

And then I found out when I got home, that there was an app from Amazon for my DroidX that has GPS and a Star Chart..just downloaded it, but it was too late...next time.


The great thing about digital, is go out and try, and see what you come up with. give it a shot, it's fun!!

Shooting the milky way is one of my favorite hobbies. There are several different methods. Here is a rough overview of what you need:


You will need dark skies. This is the primary factor. Most night skies, these days, reveal only light pollution -- very little of the milky way can get through (unless you want to do a narrow-band image of the milky way). Find a lost astronomy club and they can tell you all the good spots near (e.g. 2 hour drive) and far (8 hour drive). What they can

Ooooh I like this topic (Hi everybody BTW - it's been a while between posts for me)


First of all, here's a pic I took of the Milky Way a couple of weeks back.

Now, the tips I have for you. If you want to create a static shot like this one you'll need a reasonably fast shot. So less than 30 secs is ok although you still might get a little movement (as you can see slightly above). To achieve this, though you'll need a high ISO. This is much easier with a full frame camera because the high ISO performance is much better than a crop sencor. Lightroom 3 handles noise very well for me as well so that helps.


If you want to get some good startrails you can either stack a bunch of shorter exposures or take one extended exposure like this one (approx 35 mins)

As Daniel said, a dark sky is a MUST. Too much ambient light will ruin the photo. Where I took this shot, there's nothing for a very long way. Basically the middle of nowhere.


Which lens, for a night sky the wider the better. I would love to have had a wider lens for this shot so I would say 24mm equivalent focal length (on FF) is as narrow as you'd like to go.


Tripod - check. No way around this one.


Also try to get somewhere with something interesting in the foreground - it gives the shot some perspective and makes things more interesting overall.


Hope this helps.

Thanks for the feedback guys. (and WOW Ben, that

I made a while back 17mm on your 7D should be fine. When stacking shots I've always used the startrails application. I can never get it to change to english though for some reason so I've historically fumbled my way around the German version.


When using startrails you do have to take a dark frame as you mentioned to help the program delineate between stars and just random noise - I normally just put the lens cap on for a shot and do it that way. I have attempted stacking in photoshop but it takes AGES with the 5D2 file sizes.


Here's a shot I took a while ago with my 40D and Canon 10-22mm UWA lens. From memory it was about 460 x 10 sec images stacked. I much prefer to take just one long exposure photo. Less work, better results. However this is much more achievable with the 5D2.

BTW I used a torch to light up the foreground here.
