I have been an amateur
astronomer for more than 25 years, mainly interested in imaging the
heavens (deep-sky but also the solar system). Over the years I have
acumulated quite a few telescopes (300mm f/7.1 reflector, 222mm f/5.8
reflector, 150mm f/4 reflector, 100mm f/15 refractor, 100mm f/10
reflector) that are house in two different observatories (roll-off-roof
and dome) located in central Portugal. I began imaging the heavens
using conventional emulsion-based photography but now have turned to CCD's.
In 1994 I bought a Hi-sis 22 CCD
