NXS 4.22 just doesn't have the original north and level GPS alignment routine (Meade is responsible for that); however, it does have a few other features that were not available in the older 1.6/2.2 firmware.
Hopefully the other features will make up for the loss of GPS alignment. I bought this scope used in a package deal, and it has sat for a number of years. I'm trying to get back into astronomy after a hiatus. I'm used to using a classic Meade LX200, so the NexStar is new to me. I was bummed to find the GPS not working during my first session because of the rollover problem. I purchased a hand control off of Ebay because mine was too old to upgrade, but then got bummed again when I found that they had taken away the thing I was trying to get going! Had I known that, I would have probably just stuck with my old hand control. The scope is destined to be in an observatory I'm working on and will be on equatorial mount anyway. I am giving it second thoughts. The optics and mechanics aren't as good as my LX200. But I'm still giving it a go.
Perhaps some tweaks to the alignment process might help GoTo accuracy?
I'm going to try a few hints others have offered, and perhaps do a three star alignment. I know the tripod was level when I started because I used a bubble level. I'm hoping it's not some problem with the encoders or bearings. The previous performance was pretty bad. Stuff was half the finder field of view away from center!
You will probably find my "Hand Control Version 4 User's Guide" useful to learn the differences with this new version.
Thanks. I've downloaded it and will give it a read. It's all new to me as I never learned the old version.
