Yes, interesting. Back in 2004, I posted a few times about
the filter, which at the time was the only product known as
the SolarMax. The dedicated scopes were instead called
MaxScopes. This was all pre-Meade, though; I have a PDF
of a instruction booklet that was printed post-Meade, and
it refers to all of the products as SolarMax. My old posts
from before the acquisition refer to SM and MS as the filter
and scope, respectively.

By the way, the bandpass of the filter is 0.07 nm, not 0.7
nm. The latter would have been a 7 angstrom bandpass
and would be pretty useless for disc detail. I guess I've
been annoyed a few too many times by people referring
to Derek Fisher's last-second shot as the "point-oh-four,"
rather than the "oh-point-four."
