Start Trails

Start Trails

Here is my first successful attempt at star trails. Not much for scenery, since it was at my house.

  1. Hey there. I like your star trails pic! May I ask how you took it? As in what type of camera, the exposure, shutter speed, etc? Also, did you took a photo every few minutes for several hours and layer them together, or leave your shutter open the whole time? I’m very curious! I want to take one too!

    • That one is at 200 iso, 16 minute exposure and f/4 aperture. I had the lens at 22mm. One exposure. I have a sony a65 camera, so the 24 megapixels help a little. I used a tripod, and used a shutter remote. The key to how this photo appears — is Polaris. It is the stationary star in the northern hemisphere (not sure how much astronomy knowledge you have, so I apologize if I am being basic). The rest of the sky appears to rotate around Polaris. My camera allows a “bulb” exposure setting, which means that I can control how long the shutter stays open, and that allows me to leave it open for 16 minutes. Vital to a good star trail photo, as well as a milky way photo — no moon. Any moon, even if it is behind you and out of the shot, will wash everything out for those long shutters. Good luck.

      • Thank you so much for the wonderfully detailed information!

        Although I’m abreast of basic astrology, I have little next to no knowledge of photographing the various elements of it. it totally makes sense that you would focus on Polaris for circular star trails now.

        Your blog post inspired me to embark upon Night Photography, you might like to know 😉 I’ve been out running around the rooftops here in Tokyo playing with my Nikon D40 in a way I never really have before. I studied up on F-stop aperture, ISO, shutter exposure times(including bulb mode-super helpful!). Now that you’ve replied and I’ve had time to study up on it a bit, it all makes sense to me! Even though I’ve read quite a few forums about this, you gave me a few insights that I didn’t catch from those forums, so thank you!! I look forward to seeing what else you come up with!
