This homepage is dedicated to
the Italian astrophotographer
Aldo Radrizzani that unfortunately passed away in 2005. Aldo realized a huge archive
of wonderful images of the sky, mainly from his
observatory in Druogno (Val Vigezzo, province of Verbania, near Lake
Maggiore,
Italian Alps), using a Schmidt Camera 600/400/300 (the numbers are
respectively the focal length, the mirror diameter and the correcting
plate diameter, all in millimeters). His images were published in many
Italian magazines in the years '90 and they were highly appreciated by
the amateur astronomers community. He lived in Milan, Italy, and was
a
member
of Gruppo Astronomico Tradatese and of Gruppo Astrofili G.
& A. Bernasconi of Saronno.
His images were
all tracked manually with a reticle eyepiece, at the focus of a 120 mm
refractor: this was also his first telescope, selected reading a famous
small book written by Andrenelli, that advised a minimum diameter of
120 mm for a "serious" telescope. With this one he started the
adventure in the astrophotograpy world, collecting the images of the
sky quite as an alternative to the collection of stamps, his previous
hobby, that he had to quit because of the increasing costs and number
of
pieces produced all over the world. His next step was a Celestron 8
scope, used at first in the balcony of his home in the mountains, and
then in the observatory dome, built for a bigger telescope.
A new telescope was inaugurated on 13 May 1989: a big Schmidt
Camera. This telescope was a bet as it can be used only
photographically: he invested all his retirement bonus. He was fully
compensated, thanks to the exceptional optics of Romano Zen and the
heavy mechanical support from Astrosystems. The selection of the optics
was not easy: he evaluated may options such as the new optical scheme
named Simak. The search for the best optics let him meet another
Italian
astrophotographer, Alfredo Zanazzo, that also went to California to
directly evaluate a Simak optics. From this a strong friendship born,
they were great friends, even if with opposite characters: enthusiastic
and avid of results Alfredo, meticulous and patient Aldo. Both selected
classical optical schemes, mainly because it was difficult to built the
big meniscous of Simak. Aldo selected a classical Schmidt camera, while
Alfredo a concentric Schmidt-Cassegrain (40 cm f/4).
After 10 years of imaging with the Schmidt, Aldo could not continue to
observe from the cold weather; but he selected a new telescope, used
mainly in his home on the temperate Mar Ligure, on the Mediterranean
Sea. He would still observe the sky from there if only a serious
desease forced to leave us in 2005.
