Maestro ASCOM Rotator driver release notes
Version: 2.1
Date released: 5-Jan-2026
The following are cumulative updates since the last formal release (1.0.1) of the MaestroRotatorASCOM driver. This driver is selected from the ASCOM chooser as
"Astrometric rotator control via Maestro".
Installation instructions
- 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.
- Download and run the MaestroASCOM_RotatorSetup<version>.exe file.
- Restart Maestro4. All should now function using the new ASCOM driver.
New this version
Features
- Compatible with Maestro's new, higher performance, means of communicating with software drivers (e.g., ASCOM). This is an enhancement on the previous
use of network sockets for inter-process communications using a new socket "connect and stay connected" appraoch, rather than the old (slower)
"connect, transact, disconnect" approach.
Bug fixes
- Fixed an issue introduced in v.2.0 of this driver, where some multi-threaded applications (e.g., N.I.N.A) would fail. The ASCOM conformance checker and
other clients (such as Cartes du Ceil) would work fine likely because the ASCOM interface in these apps is not multi-threaded. Driver version 2.1 of this
ASCOM driver is now "thread safe".
