This document provides instructions on upgrading Maestro4's ASCOM Telescope driver.

Installation instructions

1. Assure that Maestro4 is not running and that no ASCOM clients previously connected to Maestro4 are left running. A reboot is the best way to assure this.
2. Download and run the MaestroASCOM_TelescopeSetup<version>.exe file.
3. Restart Maestro4. All should now function using the new ASCOM driver.

Bug fixes

• In support of non-US locals, fixed the following problems...
  • Fixed the exception "UTCDate has not yet been updated from ATCS."
  • Fixed problems where the following properties incorrectly represented ATCS values:
    • DeclinationRate
    • RightAscensionRate
    • Any coordinate from ATCS that could be reported in ATCS with a decimal point in the minutes or seconds field.
• Fixed a bug where the MaestroTelescopeASCOM driver would not report Maestro as disconnected under these conditions:
  • If the hardware disconnected from Maestro (e.g., it was turned off).
  • If Maestro closed unexpectantly (i.e., not through normal exit).
• Due to the way ATCS works the following exception to strict ASCOM Telescope interface v.3 compliance has been implemented...
  • Removed the restriction that SyncToCoordinates() was not allowed unless tracking. This restriction prevented AltAz telescopes, which can't track until ATCS is aligned, from being aligned with a call to SyncToCoordinates(). This is in support of ATCS' feature that a "sync" request when not aligned will result in a one-star alignment. Of course, a one-star alignment of a non-tracking telescope will not be very accurate however a follow-up sync, once tracking is available after first alignment, will fix that.
