Cocoon Nebula, test exposure

I've been struggling the last few nights to get a good TPoint model, and was frustrated by annoying equipment glitches. TheSky and the mount lost track of each other halfway through the TPoint run on Monday night, so I had to do it again tonight. Things went flawlessly (though I had less time than I wanted, and went with 3x3 binning for the first time - results were actually quite good with 3x3).

To test the TPoint model, I took at 15-minute exposure of the Cocoon to see if I would get any trailing. This exposure looks pretty darn good, so I'm finally satisfied with my TPoint model. For those who are not familiar with TPoint, it's a statistical package that works with TheSky for improving pointing accuracy of your telescope (and, in the case of my Paramount, it also is used to improve tracking).

I think that's what must be happening to me when trying to get a Tpoint model. The Sky losing trak of something anyway. Well, at least I'm not alone
