Extension adapter ( 1x M42M-M48F ) 16.5mm
Allow 1mm of tolerance
Total distance sensor to Baader Mk3 CC is 56mm
So it is within the technical parameters of the coma corrector to sensor 55mm +- 1mm
I’m still getting a bit of coma on the edges

I, as you know have been going through the same challenges. Exacerbated by my f/4 ratio. I’ve extended the distance by 3.5mm give or take and it’s has considerably helped. It’s still not perfect but it’s a lot closer. I shouldn’t imagine yours will need to be increased by that much but maybe if you can add another mm or so and try it ?
