RE: [APML] Tak FSQ-106

["George Whitney" <gwhitney@maine.rr.com>]

To the Group,
Are there others out there with experience, pro or con, with the Tak FSQ106
and a 6x7 Pentax combo?  I am looking into acquiring one and would
appreciate any feedback regarding the scope.  My many thanks.
George Whitney

Vignetting? No. I had a relay stuck "on" in my STV last month as a result I
only got two pictures that weren't ruined by the mount slewing way off the
shot. Neither show any vignetting. They are sharp as a tack all the way
across the shot too. I recall some people saying the FSQ has a "hot spot", I
can't see it in my shots but I would like to do some more before I can say
it with certainty.

Regards Monte
