Creating Separate Profiles for Planetary and Standard PHD2 Versions - Eyeke2/phd2.planetary GitHub Wiki

It is recommended to install the custom PHD2 version for Planetary Guiding in a separate folder from your standard PHD2 installation. This setup enables you to swiftly revert to the standard version of PHD2 should you encounter any issues with the custom variant. Although the custom PHD2 version encompasses all features of the standard PHD2 software and is equally effective for star guiding, this precaution serves as a safeguard and a convenient fallback option.

Furthermore, there is a standard PHD2 feature that allows users to create and manage separate profiles for different guiding sessions, such as planetary guiding and night-time star guiding.

By using the command line parameter -i [instance number] in the PHD2 application shortcut, you can effectively run separate instances of the application, each with its own set of configurations. For instance, specifying -i 2 launches a second instance of PHD2, enabling it to operate with its unique settings for variables like exposure times, delays, algorithm settings, equipment profiles, and window positions.

When using an instance number other than the default #1, be aware that the PHD2 server port used by the client application must be updated accordingly. For instance, the default port for instance #1 is 4400. For instance #2, it's 4401; for instance #3, it's 4402, and so on. Technically, the port number is 4400 plus the instance number minus one.

This functionality is especially advantageous for astrophotographers who switch between planetary and star guiding. It allows for easy transitioning between sessions without the need to manually adjust settings each time. Simply use a different instance number (1 is the default for the primary instance) to maintain multiple, independent sets of configurations that cater to your specific observing needs.

Leveraging this feature can significantly streamline and enhance your astrophotography experience by keeping your planetary and star guiding environments distinct and readily accessible.
