DSLR Sub length and ISO question on guided exposures

Hi All,

What settings should I use for subs when using my Canon 1000D (CMOS) DSLR?

I have been trying 5 mins @ ISO 400 (looks washed out), 60 secs @ IS0 800 and 1600 etc and I am not sure what works best.

I know the brightness of the target comes into the equation (and probably skyglow is my issue), but I am after some guidance on a happy medium to get me started now that I have my guiding working so that the image subs arent too grainy which makes me think they are wrong and I throw them away.

Or do I simply process them properly and the washed out look goes away when using flats/darks in the right way?

Any help here would be appreciated so I start on the right track. ie for Eta C, try 20 subs at 5 mins @ ISO 100 for example.....

Thanks

Chris
