Quote:Try this and test itJust a FYI, just before I deforked my 9.25 I had upgraded handset and seem to remember that for one mode to stay locked in (alt/az?) the scope has to be aligned. Put it into just a quick or fake align and see if it changes,, Kasey
Quote:You may also try a factory reset on the hand controller. Mine has gotten garbled up in the past to the point where it did very odd things until I factory reset it.

Quote:Not much of a problem IMHO. I've been doing it for over a decade without a problem, anyhow. The GPS series of scopes worked exactly the same way: tracking off till aligned, then alt-az tracking kicks in.Alt-az tracking requires different motor speeds depending on _the position the scope is pointed to in the sky_, so until the alignment is done, there's not much point in starting tracking.
Quote:Jon, to quote from a post by cn register 5 on the Cats & Casses Forum where I raised the same question I raised here:"Part of the reason that the Celestron AltAz mounts don't track before they have aligned on at least one star is because of the Meade patent on starting at a known terrestrial alignment. Without that the scope doesn't know which way to track. If it makes some assumption about which way to track it could be said to be infringing on the patent."So, yes, it's probably true of all post-patent Nextar mounts.
