Just curious as to others views for imaging in which should be given priority, ISO or exposure length and how many images are worth stacking? Can you have too many to stack ?

Tested out a Vixen Polarie Sunday night with an 1100d attached, started at 60secs and worked up to 12 minutes with ISOs from 800 to 3200. Ended up with a mixed bag but I'm not up with processing so I may not be seeing what others see in an image.

The Polarie was what I was focusing on and it's tracking capabilities, I just dropped the ISO down as the exposure lengths increased or if the images were too bright.

With the 1100d being a fairly common camera here, before I give it another try I thought I'd ask others advice on what direction I should take in regards to the exposures. What I should looking for

There's a couple of images from Sunday night attached, just adjusted levels, all the same way, nothing else.
2 and 4minutes at 1600 and 5 and 12 minutes at 800

Cheers
