Ok, the details were like this:
Got the 350D going on the EQ6 with the 70-200 f2.8, we were at 135mm @ f2.8 with an ISO of 400.
Plugged the 350D into the laptop running ImagesPlus, set the image run and then departed back into a warm house where coffee and biscuits waited. Essentially from there it was just tapping into the notebook outside via wireless link to retrieve the images. Simple and very effective.
Used Deep Sky Stacker and stacked the frames as they came in, the only problem with sitting inside is that we didn't see the cloud approaching and that pretty much shut down the imaging for the night.
Need to look into some type of autoguiding soon, need longer exposures
