Yes, of course.
This picture could be used in a beginner's
textbook to explain what is "collimation error":-)
Modern sextant scopes (for the reasons that excape me)
do not have collimation error adjustment,
with one exception: the inverting scope of SNO-T.
Once Bill suggested to adjust collimation error
with a hammer...
This is apparently what the owner of this sextant did,
and after he failed, he sells the sextant:-)
