The internal blackening can also be easily improved on a refractor, Maksutov, or Schmidt-Cassegrain.

These require a bit more effort, as you can rarely work with a paint roller due to the smaller diameter of the tubes, requiring more care.

However, better internal blackening always improves contrast and sharpness at least slightly, as stray light is minimized, thus reducing reflections that interfere with the image.

With a Maksutov, blackening the baffle tube is often sufficient.
