tko stands for tom knight optics
or tk optics. all the tko scopes
are my own design. the scopes
may use real vendor components
on the scope. this is a 127mm
or ~5" apochromatic. it is an f:5
scope which is a very fast but
low power scope. it uses a 3.5"
feather touch focuser and
lumicron diagonal. it has a
sliding dew shield and a
sliding weight for balance
the scope is fully baffled inside.
like all my scopes everything works.
