Meade has recently started shipping a new version of the "497" Autostar. It appears that these are totally different from the 'old' ones and AutostarX won't work with these. I haven't been able to experiment with one of these new 497 and don't know yet the extend of the changes. I'll post an update as soon as I know more about this. AutoStarX allows you to upgrade the flashrom of your Autostar on Mac OS X (495 and 497 only for now). You need a USB to serial adapter (keyspan, ftdi,...) and of course a Meade 505 serial cable (or a home made one). Download AutoStarX version 1.4.1 (universal binary)(100 KB zip file) Any feedback and comment are welcome via email : pineau at rti-zone dot org you want to support the development of this program : Meade and Autostar are registered Trademarks of Meade Instruments Corporation.
