Galaxy 22" f4.5 optic with interferometry. 96% coatings.
Some micro-scratches due to dirt/cleaning, but otherwise
in superb condition.

SN01462 Figured by John Hudek 5/17/1995.
John's comments:
"Your optic is Top Notch!!! Please note that the wavefront
astigmatism is 1/45 wave and the spherical aberration is
only 1/15 wave on the wavefront...WOW!! This optic is

Note the PV is better than 1/2 wave over the entire surface, and
much of this error is confined to a slightly asymmetrical
raised edge. The spherical aberration gives a good indication
of the performance of this mirror.

Unfortunately, due to illness, I can no longer manage a
telescope this large.

Best offer over $4000 with pickup in Denver CO area.
Higher if shipped (let's discuss, because it needs a
crate -- 72lbs).
