My AOX is about 5 years old...still works flawlessly. The SBIG version does not use motors. Electromagnetic coils are use to modulate a "floating" refractive element's position.
Good to know - thank you Peter.

As for star shapes in front of the corrector - I believe that uncorrected field curvature in front of a flattener and far away from the optical axis will most certainly result in highly elongated star shapes in a guide camera. Whether that would impact guiding - I donít know.
