“The optics in this telescope are of a high quality level for serial produced optics and are showing good spherical
correction. It has a very faint turned edge, which is also visible on the Ronchi-images. The optics are
not as smooth as most Maksutovs , which is slightly visible in the infocuse images.”

Note: ronchi-testing with 254 lines/inch or 100 lines/cm.
