Really?

I should try that.

I did turn Protrack on for some of the exposures. I had a few that were no good but it is probably cable drag or imbalance so I turned it off.

300mm F4 also looked good at 5 minutes. I may have done a 10 minute on that as well.

I wonder how big a T-point model you would need to do 100 inch focal length 20 minute exposures?
