m-m-m-m-b-b-b-but my current focuser only slides the barrel up and down, closer or further away from the secondary mirror.
that's all it does.
which means as much as moving my camera closer or further away from an object.
from what I can
see in pictures from T-mount accessories, they DON't have any optical mechanics, either - they're just plastic stuff to connect parts with each other.
right?
or is THAT the false assumption that makes my hair grow white?
