I have a Alter 603 that I traded for from ITE as
a scratch and dent model. None of the imperfections
that are described have any detrimental effect on
the performance of this telescope.
The meniscus lens as some very fine scratches
that I believe are in the coatings and do not effect
the scope optically, this is reflected in the optical
report from Mike Palermiti and is also backed up by
Bill Burnett. Specs are 1/6 wave at 555nm and a Strehl
The tube finish has some minor discoloration of the
paint and small scratches.
The OTA includes the standard 6x30 finder scope and
dovetail mount with adapter plate and covers for finder
scope and OTA.
Asking $450 shipped and insured in conus. will include
baffled screw-on dew shield for an additional $50.
