Not sure the 18mm CEMAX is a must have: around 10mm still gives a full
disc image. The supplied kelner is fairly good - certainly not 99$
better than the kelner and the image is much smaller.

I use my PST a lot with children and adult newbies - the longer
eye-relief of the ceemax can be a problem as newbies tend to get too
close and perhaps see nothing without being talked through it.

But the PST is astounding value: a breathtking addition to the
arsenal.
