Milky Way - Shot with Rokinon 24mm f/1.4
 
I went to Mt St Helens for a Milky Way workshop this past weekend. I was using my D700 with a Rokinon 24mm f/1.4 manual focus lens. I used Exposure Delay on my camera which effectively puts the mirror up and takes the shot after a one second delay while using only one shutter press.

Here's one of the images. I used an aperture of f/2, 15 seconds shutter speed and ISO of 1600 to get this shot.

Looks nice. Is 1/15 the slowest that can be used without blur?

The answer to your question is "no". The instructor recommended we use 20 seconds as the longest exposure and I actually did use 20 seconds for my longest exposure. However, for some reason, perhaps a faulty card reader, I received error messages in Lightroom when trying to import all of the images on the card. It only imported a few of my images and the longest exposure of the images that were successfully imported was 15 seconds.

. . . And I would say, 15 seconds was right! Nice, Ellen!

Using the 500 rule. 15-20 seconds is your sweet spot with that kit.

Great photo! Well done!

Edit: The 500 Rule

500 divided by your focal length = longest time without star blur/trailing.

For crop sensor cameras. Divide that longest time by your crop factor for your adjusted exposure time.

The 500 Rule. Thanks. Very nice shot Ellen.

Thanks all for the kind words on my Milky Way image
