I wonder about the effectiveness of baffles in newtonians.
On a refractor, you are viewing from the non-illuminated side of the baffles, With a newtonian the face of the baffles illuminated by external light is plainly visible from the focal plane given that you can see greater than the width of the primary reflected in the secondary mirror.
The other downside I can see is the impedement to tube currents skimming the tube wall and being kept out of the optical path.
