Ok for anyone who's interested in the 127ED.
This gent Wolfgang Grzybowski's tested a 127ED scope under the generic name
"OMEGON" (at the bottom of the page). He had big troubles with it with: coma; astigmatism; and what appeared as a flare (blue/violet) (I'm reading into that but his pics show this was happening).
To give you an idea of how bad it was..the Strehl was .17!
and the rest of the figures were poor as well.
He inserted new spacers, re-shimmed & adjusted the lenses and ended up with Strehl of .93. Much better.
This looks pretty much as what I was getting in my scope. I was also getting funny shaped stars across the field with coma and flaring.
It appears he liked it after he did the adjustments.
I hope mine (lens cell) comes back as good as this?
edit:
It appears..
lens spacers are available (or suggested) in Europe as a retro fit for these lenses. He also appears to have some commercial interest in this OMEGOM brand as they listed his Optics adjustments "guaranteed performance" from the astroshop.de selling these scopes. Thus he must test and adjust each scope.
