I just checked the qhy8 sensor height to the thread at each corner and it was tilted by around 0.7mm at two corners.
will have to sort that out first.
also, the spacing to the mpcc doesn't look quite right.
from my measurements, its about 59mm at the moment.
The baader site and other sites mention the use of the mpcc stop ring for photographic use. is that necessary? I normally remove it and slide the mpcc/qhy8 into the focuser as otherwise, I don't reach focus with a standard profile focuser.
