I meant 16HZ in the title... I'm wondering if a firmware update will solve the problem I'm experiencing (currently on v2.41 vs 2.49.02 I've just replaced my STX16803 with another identical model. All is well except for the AOX. When the AO attempts to run I get guide star fade and the rate stars at either 10Hz or 16Hz, but it is is not actually doing anything. There is no star in the guidebox, but there is a star on the chip. While I would like these sorts of speeds there is clearly something not right. I'm running Maxim v6.12. The firmware is back level (not shown here).
