18 UC comes with primary and secondary light baffles

Hi Tim,

The scope comes with Kydex light baffles both for the secondary and the
primary, it is just that they were not installed during the daytime when I took the
photographs. You can see the light baffles in the attached photograph taken
by an 18 UC owner at the recent Okie Tex.

In keeping with the fast setup time, both baffles attach in just seconds.
By keeping the primary baffle removed until one starts observing, this may
also assist with the mirror cooling down to ambient much more quickly.
