Great shot, just curious, ever try taking your ISO down a little?

Great shot, just curious, ever try taking your ISO down a little?

I was trying to capture individual frames with very little trailing (because I also wanted to create a stacked image of the sky with no trailing) -- so I needed a short exposure -- in order to capture enough stars with a short exposure, I had to use a high ISO. Besides, it's a trade-off. At high ISO I can use a short exposure thus reducing thermal noise. At low ISO I'd have to use longer exposures, which would increase thermal noise. Also, each camera has an "optimum" ISO (here's a very detailed, very technical discussion on it Cloudy Nights about it). For the 40D, 1600 is actually better than 800 in terms of signal/noise ratio.

Usually I do dark frame subtraction for astrophotography anyway, so I don't worry too much about noise.

[samthaman]

dumb question, but what do you use to stack that many photos together without having your computer crash (or to you just have a really nice setup)? Do you use a remote intervolmeter (how is that spelled?) or the EOS utility? any reason to use one over the other?


Looks awesome though, and I'd love to try something similar.
