Date released: 14-Apr-2026

For all devices

New Features

Password protection of hardware settings

From the Settings --> Common --> User Interface dialog, the protection of hardware settings can toggled on/off after successfully entered a pre-set password.

When "Protection Enabled" is checked, then when clicking into, or typing into, a settings dialog that involves hardware settings will result in the message

"Settings are password protected. Go to Settings --> Common --> User Interface to un-protect settings.". Changing the protection password:

To change the password first enter the old password and then enter the new password twice. If the 2nd entry for the new password (i.e., the "Confirm Password" entry) does not match the new password then the "Passwords Differ" indication will be provided.

Note: The purpose of this feature is to prevent inadvertent settings changes. The purpose is not to bulletproof against malicious intent which should be protected against via more secure means such as controlling access to the PC.

Note: If the password is lost it can be recovered by inspecting the user.config file as follows:

Save and restore of Mastro software settings

Prior to Maestro 0.09.017, the hardware settings for connected devices could be saved to a file of the user's choice from the File --> Save Settings to File menu. These settings could then be restored from the File --> Restore Settings from File menu. Hardware settings comprise the bulk of the system settings for Astrometric products since the functionality is predominately in the hardware. However, there are some user interface related settings in Maestro software. Maestro 0.09.017 now saves and restores Maestro's internal (software) settings to/from the selected file. This includes communications settings, network settings, notification settings and Maestro's device-specific settings. With this new feature, all settings associated with the software and hardware system are saved.
