In my limited knowledge I wouldn't have thought so. I can see the entire sensor with space around the edges when looking through the entire OTA from the front. Although I guess that might not be a factor.

Interestingly for comparison I found a test shot from when I first got the scope, tested with the 0.85x reducer/correcter in question and my 6DII attached with a T ring.

This is the middle right edge of the frame.

It was unguided at the time on a HEQ5 Pro. Looking at the star shapes across the whole sub shows tracking error, but wouldn't cause the tails on the edge stars?
