Knowing that there are a wide variety of opinions about reflector's vs. refractors, all I can
say on this issue is if one wants to enjoy the finest quality tool for observing the planets and the Moon the reflector incorporating
the tool of the 3 vane curved spider will give the best performance under most conditions.
My experience in making this observation comes from my own backfround from having done observing
with such a system within several feet away from a large aperture refractor in addition to countless statements of agreement
by others more experienced than myself as to the quality of the optics.
Alberto in the Fall 1990 became well known in the astronomy community from having co-discovered
a large white storm on the surface of Saturn. (Sky&Telescope)
The truth stands as the facts are the facts, I have seen it for myself along with others, Alberto's
legacy shall live on through his works of art.
