Greg, there may be some other bug that has not been fixed . A guy with a very good T-Point model in place has reported that Protrack seems not to be working correctly. Then another poster pointed to an older thread by our friend Josh that showed that sometimes Protrack corrections were not beig applied even though both check boxes were enabled. But, turning Protract off and then back on temporarily fixed the problem. Something similar might be going on stiil on occassion. So, if you get RA drift with Protrack on just try the off/onn technique to see if suddenly Protrack works as expected.

Ok that makes a lot more sense, I interpreted it a little different / dodgy haha, apologies.

This pro-track thing does bother me, I have observed similar behavior and have to admit that I kept pro-track turned off for many months. Using the AO unit on the SBIG, I found that with 30min subs, not one single "bump" was required, so I felt comfortable with it off as my tracking didn't really have any noticeable drift that the AO couldn't handle over long durations, or at least in a 30min period.

Now I'm back to OAG operation with the MMOAG, so with Pro-track's ability to counter a lot of other variables I'd like to know it actually works lol
