Hello Group ,

In the August issue of Sky and Telescope Mr Gary Seronik
does a review of the TMB Optical monocentric eyepiece and in my
reading of it comes to the conclusion that there is very little
difference (or none)in contrast and light scatter between the mono.
and two well known Plossls and a symmetrical . Three high quality
eyepieces to be sure but I would have thought more of a difference
would be seen between them and the mono. Mr Seronik did what appears
to be a very complete review . It comes as no surprise that in an F4.5
newtonian off-axis performance was less than excellent with the mono.
What do you all think about this review after such glowing
reviews from other people over the last few months ?

Personally, I think the phrase "your mileage may vary" was erroneously left
out of the review. I guess that's why there are so many different ocular
designs out there and each has their loyal following. g

Best regards,
Bill
