First attempt at star trails.

    First breakup in trails I removed 10 frames due to flarring from camp fire nearby. The rest of the breakups resulted in battery issues.
     
  2. Interesting, nice long trails. I tried once ages ago with my F100 & film when we were on top of a mountain in NC watching a storm in the distance. I didn't get any lightning strikes but I did catch a couple shooting stars

  3. Pretty cool- about how long was the overall exposure?

    Cool. I want to try this before the summer is out. I would like to know how long your exposure was for this too.

    The original at the beginning of this thread took nearly 2 hours. However the shorter cleaner trail version posted here is only 20 minutes.

    Did you stack images of shorter intervals for a TOTAL exposure of 20 minutes? Or was this a single 20 minute exposure?
     
  8. Was that stacked in software? I like the long star trails, I always wanted to do one that led pretty much all the way around :)

    What ISO was the film? That looks pretty clean!
    Also I believe those are satellite's in that pic

    Nice star trails ! Yes I too am wondering on your technique.
     
  10. Niiiiiiice !

    I am also interested in the technique used for these images !?!

    :confused:

  11. At first i was attempting simply using a super long exposure with a MC-30 remote cord with trigger lock in BULB mode for the shutter. However I think is inherent a problem with digital is "dark noise". A super long exposure heats up the sensor which creates purple/pink haze that really isn't there in the image. This doesn't happen with film I guess because heat isn't generated.

    To fix that problem I took multiple frames at 30s each and stacked all the images using tihs program. I think realistically for 30s frames all you need is 20 mins worth.

    But you WILl need a MC-30 remote. I set the camera in burst mode (NON-bracketing) on CH with a EXP delay on to minimize shutter shake. I set it on manual for 30s f/4 ISO 800 I think.

  12. Thanks a bunch for the tips !

    BTW, what F-length did you use ?

    Cheers,
