I find it a little sad to see that Albert is finally selling a slightly modified version of the 16" from Portable Newtonian Telescopes. It is only $2625 for it, really a steal for such an incredible instrument.
Albert's scope inspired my 14.7" f/2.89 Dob.
Maybe he is making another.
Or since he is selling it for less than the mirror price, it sounds like ...
several things. Even the mirror does not hold its value after use.
Well, he says it is priced to sell fast.
