I’m trying to diagnose some tilt in my setup. To collect data for this, I’m looking for a reliable way to focus in specific areas of the image frame (top left, top right, etc.) If possible, I’d like to use Voyager’s VCurve to do this.
I don’t see an obvious way to ask Voyager to focus on a subframe, but I’m wondering if I can still achieve what I want by using the “AutoFocus @ Actual Position” action under the “On The Fly” tab.
The wiki says that AutoFocus @ Actual Position uses a “suitable star” at the current scope position. How does Voyager determine the “suitable star”? Does it pick the brightest star in the field? If yes, I can just achieve what I want by moving the scope until there’s a single bright star at the position that I want to focus on.
