Re: Struggling to get my old LX200 GPS going... (Autostar problem?)
- I fixed two LX200GPS scopes - an 8" and a 10", both of which had the problem
of Polaris being 10 degrees off by doing the calibrate sensors utility. I
don't think it has anything to do with wireless box.

- Thanks Dick, thanks Dennis,
That's great advice. I shouldn't forget that I still have to make sure that was my problem and enjoy re-learning the scope (and re-reading the manual). Re-learn to walk before trying to run so to speak. I'm glad to see this group still going strong.
Have fun everybody!

Until you're (again) familiar with its operation,
i would NOT recommend upgrading (and i certainly don't recommend a senseless reload if it ain't broke).
Updating object data is fine.
Then, after you're rolling again... read the "what's changed" of v4 over v2, and decide if you want the features.
For example, v4 has full three-cycle PEC for RA, correcting for the entire gear chain from motor to worm (instead of the single-cycle worm-only of v3 and earlier).
BUT, if you don't use PEC, that doesn't buy you anything.
There are still folks happily using everything from v1.2 through the one-shy-of-current. If the scope's doing what they want, there's no reason to change.
have fun (and keep re-reading the manual)
