My subs out of the 2600MC are 50MB fits files so can’t send but I did check all 8 subs in the corners with ASTAP and the stars were 95% 100% coma free. Only the top RHS corner of the frame near the edges showed a very slight coma when you zoomed in , hardly noticeable and not worth worrying about
Yes it is strange about f5 and f6 newts with same spacing to eliminate coma but their focal lengths only differ by 100mm , f6 being 900mm fl and f5 being 1000mm
I’m sure faster optics ( f4 and lower ) are harder to get spacing right
Thanks
Martin
