Answer You probably flashed it with the wrong version of firmware, one for another mount. When you do this, you may get the telescope model displayed correctly when your scope is powered up, but a completely different menu. Or you may get “No Response” or another model of scope displayed.

You can fix this by simply reflashing the hand control for the correct version of the firmware using the HCupdate software.

The different firmware versions versus telescope models are described on the NexStar Resource Site firmware page. Here are the latest version numbers for each mount (April 2009). Be sure to choose the right one in HCupdate when upgrading-reflashing.
