Is there support for an inexpensive "usb box camera"?
Like the ones used on drones with S mount (12mm) lenses?
I'm wondering about an under $75 or $50us solution for Polar alignment, for folks with guide scopes that are too long or using off axis guiding.
I would guess IR monochrome would be best?
25mm f1.4 or f1.2 IR lens is doable ($12US) in that price range (and similar FL to polemaster). Huge FOV compared to 0.5 degrees, however.
