PHD2 Update Stellarmate OS

StellarMate OS keeps showing a notification that a new PHD2 version is available – but what’s actually behind it? I dug in, worked through terminal output and apt packages, and finally dissected the package itself. The result is surprising.

While mono remains efficient, the RGB workflow is time-consuming, and early tests with two cameras have shown that it can significantly reduce routine overhead. As a result, my focus has shifted less toward pure image quality and more toward handling and workflow efficiency.
