Thanks Gary.
There is something appealing about a physical method rather than a computed method. You are more in control for one thing rather than some behind the screen computation which may have errors in it.
My experience with Tpoint is overall quite positive, though as I have said its not always bullet proof as basic assumptions are made and they can be violated or the software has glitches in it which has happened a couple of times now that throw you off. And because that is hidden you may not pick up on it except for the clue from non round stars or guiding software showing drift is occurring.
Greg.
