Well, this is OK for good, permanent site, properly housed, high up on top of a mountain, far away from cities..
I am not sure there are many amateurs who could or would want to afford something like this... but then again, who knows... In Germany there is one guy who goes around with 1m dobson (!!!)
In my view, it is absolute waste of money and time - the scope is big enough to offer a glimpse into serious stuff, but everything else with this design is just not adequate for any really serious work.
People with aspirations for such apertures should simply forget about big-boys toys and start doing professional work.
IMHO.
