MISTAKE IN THE SUBJECT LINE: The camera is a 5D Mark III...

 

I would like to take time-lapsed images with my Canon 5DIII. I used to take astro images with a 20D, but that camera no longer works, and I've been using CCD cameras for a number of years now. So, I have a few basic questions:

 

  • Can I get away with using just a USB cable to take images with the 5DIII from SGP (or any other application)? Back when I used a 20D (with Nebulosity at the time), I think that I needed a special cable to actually take the images, while the USB cable was just for downloading the images. 
  • Is ISO 1600 a good setting? I'll be using a zoom lens at 24mm which has a max aperture opening of f/4.0. I'll experiment, but my starting guess is ISO 1600, f/4.0, 30 second shutter, sRAW.
  • Should I enable mirror lockup? If yes, does it lock/unlock on every image?
  • Anything else that I should be aware of?

Thanks,

Dave

Apologies, I posted too quickly - I answered some of my own questions, but have some others:

 

  • It seems to work fine with just a USB cable, i.e. I can take a sequence of images and download them from SGP.
  • It appears to only work in Bulb mode (which is fine). I keep getting an error message when I set it to Manual mode.

My new questions:

 

  • Is it possible to skip downloading the images to my computer, and just store them on the CF card on the camera?
  • If yes, how is there a way to set adjust the image size? I'd rather not use full-size RAW images, although admittedly I probably do have enough storage on the CF card to meet my needs.
  • If not, SGP stores the images as FITS files. Can these easily be processed into time-lapse images? What software would do this?

 

Thanks again,

Dave
