I would like to hear from anyone who might also have bought from Mark,
as to how they rate his product. I have an very early 8" f6 that came
with excellent specs (max < 1/28 wavefront, RTA 0.229 RTA, specs
suggest use of a 5-zone mask) and a note on slight TDE.

I haven't had it long enough to fully evaluate. From what I've seen in
star testing under less than ideal conditions, the mirror seems to be
zone free and have nice even patterns. Also, a hint of the TDE, to be
confirmed under better conditions.
I did a search here and came up with a total of three hits. I've his
ads on Astromart so these mirrors must be out there?

Felix, I would be glad to discuss my Mark Harry mirror with you via email.
Mine appears to be the best optic I have owned, even under miserable
conditions.
