Once I have a reliable 3 point calibration, then on a 80 point sky model in MaxPoint it tells me it can point my Atlux within about 55 arc seconds of the target (versus 3 arc minutes raw).
The alignment error it tells me is about 1 arc minute West and 5 arc seconds low of the SCP. It gives me measures of flexure, cone error (no mount leveling errors) and misalignment between the OTA's light path and the mount's axes in the 5 - 15 arc seconds generally.
So for my mount I find MaxPoint improves pointing on a well aligned, rigid optical platform, on a permanent pier threefold.
Let's say you get the same improvement - what is the current quality of your pointing ability all over the sky? Do you have any feel with what you are starting with?
Tpoint seems the heavier duty, more capable software (at double the price) - but I'd be interested to hear Fred's views on how capably MaxPoint vs Tpoint can improve all over sky pointing on his gear!
