As the "readme" in the patch kit says, you have your CHOICE of using ASU or StarPAtch.

If you use ASU, you first have to get the original 4.2g ROM file and the
patch kit's patchLX42gg17.txt  file into the same directory, along with
(to make it easier) the "ClickMe" file that's in the kit.
Then double-click the ClickMe file.
That will create a new file   buildLX42gg17.rom

Put *that* file into
C:/Program Files/Meade/AutostarSuite/Updater/Ephemerides
(if you have Windows Vista, Windows 7 or Windows 8, the above becomes:
C:/Program Files(x86)/Meade/AutostarSuite/Updater/Ephemerides

Now you can run ASU, and tell it to use the Local file.
It will present a drop-down list of files it thinks approprate, and
"buildLX42gg17" should be among them  (if it only offers version
numbers, choose  4.2G  (uppercase))

StarPatch installs *exactly* the same file as you'd create above.
It presents the choices of sub-patches as a tick-list, with the defaults
the above process chooses already pre-ticked.  No more, no less.
StarPatch handles all of the fluff-and-bother of fetching and modifying the patch and the ROM files.

I use them both interchangably  (for the 497 Autostar, StarPatch is *far* faster)

StarPatch is free from

good luck

I have the older version 4.2g for my autostar ll and I see on your site
that there is a new 4.2G update. If I choose to use the ASU from Meade
will this include Dick seymours patch kit or is this just a different
way of patching? I'm fimiliar with Meade and the ASU and would fill more
comfortable going this route but I dont want to miss out on anything
exciting. Thanks for your help.

Mike here: 4.2g is the latest version of the AutoStar II software. To install patches you use StarPatch from


Thank you Mike, I see this is a third party patch. have you done this
patch yourself yet and if so was it easy to patch? Mike another
question...have you tried the polar aligment software 
"Alignmaster" with your LX200? link here.  
Mike here: I avoid using Windows. So haven't done patches or used that other software.
