If I put the guidescope in the middle and had the cameras on each end, would this still affect the images?This morning when I looked at the images, I noticed that the stars to the left of the frame were not as round as the stars to the right of the frame.This was visible on all the shots from both the 135mm lens and the 24mm lens.
Could this be a result of having the guidescope on the far right of the platform?
What are your thoughts?
The position of the guider on your plate doesn't matter. What matters is which star you guide on (point the guider to) in relation to the center of the FOV of the imaging cameras. Ideally it should be fairly central to the FOV so field rotation won't show up as much if you PA is not spot on on long exposures.
