Toucam Equivalent ISO
Hi Everyone,
I am trying to decide if I would find a Toucam (with Long exp mod) valuable as I already have a Canon 20D.
I don't really plan on getting into planet imaging.
I was wondering how the sensitivity/noise of the Toucam compares to a 20D (or 300D as its similar).
Does anyone know what the equivalent ISO of the Toucam would be on say medium or high gain setting?
What I really need to know is.. Will I have to expose the 20D much longer than a Toucam to get similar brightness of image?
Cheers,
Dave.
