60 minutes of Night Sky

Newer Older

A full 3600 second exposure of the night sky. The rotation of the earth makes the stars move slowly across the sky. Each one of these arcs is 15º.

Unfortunately, Leaving the shutter open so long causes a lot of noise. If anyone knows how to avoid this, please let me know.

There was a bit of cloud coming in from the West, which caused the orangey glow and some of the stars to be occluded in the bottom right of the picture.

The smudges in the upper part of the picture are the 2 Magellanic clouds

The bright star on the left is Canopus (I think).

    This is awesome! You must be in a low light, no light area!

    I use to do single long exposures. The last one I tried, I left the lens cap on but did not realize it until after the in camera noise reduction processing was over! I waisted a lot of time! :) But now I stack!

    I do a series of 30 second exposures and stack them together. The end results is, in my opinion, better. It makes it so you can get a more correct exposure for your foreground. Some say that you take a "black" exposure, with the lens cap on, and stack that with your processing and you get less noise. But I have not seen any difference with that. Any way, the other night, I did a total of 327 stacked exposure, each 30 seconds long. This was my end result. When all was said and done, including the time between exposures, which is unavoidable, this took 3 hours to make, the processing, probably a while...LOL, I let the computer do its thing while I did other things. Time consuming, however easy!

    I recently went to the Cederberg for the weekend to get some more shots of the stars.

    One of the main things i wanted to do was take a time-lapse clip of the stars rotating around the earth (or more accurately the earth rotating).

    As there are no cities or even towns nearby, it's the ideal place to do it. I got up at about 02:30 and sat outside in the freezing cold for a few hours listening to my camera Cluh-Chick every 30 seconds satisfied that it was in focus, the lens cap was off and the battery hadn't died.

    However, when I packed up to go get some sleep in a nice cosy warm bed, i discovered that my camera was DRENCHED with dew. I got a total of about 20 shots before dew covered my lens. I tried again the following night, but got the both angle and focus wrong :-(

    I will be going there again, maybe when the weather turns warmer in 6 months time.

    Hello Blyzz. Inspiring photo. How do you add the rectangles and comments to the photo?

  7. Blyzz 45 months ago | reply

    thanks, click and drag on the image in flickr, then on "add note"

    Thanks Blyzz for explaining how that is done. I would never have found that out otherwise, and I have been wanting to do that for ages!

    @Blyzz You could try stacking a series of shorter exposures together using a special program. This can reduce noise.

    I'm going back to that area of the world at the end of Jan - I've been told about stacking before (by people at the observatory there as well as by CuteAsABugOnARug 18 months ago- and seen some interesting stuff done with it... I'm definitely going to give it a shot (pun intended), but I'm probably also going to use the exposures to make a video clip or 2 as well as trying a single long exposure followed by a cap-on shot of the same length to remove the noise.

    Also have a few ideas about where to shoot it to get some interesting foregrounds...

    I managed to get this shot with a long exposure. Using the Tungsten white balance setting will also help to tone down any orange glow.

  12. Blyzz 42 months ago | reply

    @Stephen_R That's an awesome idea - I'll give it a shot

    Getting interesting foreground detail is the battle! I look forward to seeing what you come back with when you go out again!
