Re: Best long exposure night photography approach without cable remote?

I'd give a couple options.

  1. If you have a paper clip, wire, or other bendable metal that conducts electricity, you can try shorting the plug where the remote goes. If I recall correctly you need to short the two pins that are farthest from the crescent shape. If you can wedge somethign in there, the shutter will stay open. If it's as dark as you say, if you have a slight vibration for the first half a second and last half a second of exposure while you install and remove the short, it shouldn't be a problem, but if it is you can do so with the lens cap on and use the lens cap as your actual shutter.

  1. Re-evaluate if you need to be stopped down as far as you are. If you can open up a bit, it can help.

  1. You can take several 30 second shots at higher ISO and use Photoshop's statistics blending modes in Mean or Median to remove noise and build up bit depth.

  1. You can take several under exposed shots at base ISO, use Photoshop's statistic's blending modes and then push the exposure by cranking up the levels. This may actually produce more noise and have less bit depth than the higher ISO method, but if you want to say you shot at base ISO, you can do this.

  1. There is a version of the Canon Hackers Development Kit (CHDK) is available for the 20D. There is a way to write scripts for your 20D to that may let you take longer exposures (not certain on this) or to take several 30 second exposures in a row. A little scripting knowledge would be helpful if taking this route. http://chdk.wikia.com/wiki/CHDK
