George Stephanopoulos observing with his C8
George has been systematically observing variable stars since 1969.
This is prior to my making his acquaintance in 1972 in Athens.
George is currently taking daily sunspot counts too.

George and I observing variable stars in Aghia Paraskevi, Attikis
in August 1979. We are using George's 4-inch F/15 Polarex refractor.
George is at the eyepiece.

Iakovos Stellas

Iakovos has an exceptional talent for making consistently high quality
planetary renderings. It is an art form that is not practiced as much
in this day and age. I am looking forward to seeing his renderings
of the planet Mars this year, 2003, as Earth and Mars will be at their
closest within the past 25,000 years.

The above four images show a completed 16-inch Dobsonian, using Meade optics that were originally housed in a Meade
16-inch Dobsonian, constructed by John Rozakis of Athens. John is also a very accomplished astrophotographer. John
is currently using a C14 and a ccd camera to do supernova search. The telescope is housed in an observatory of his own
design and construction.
 

Dimitris Kolovos and his C11
Since I met Dimitri in 1994, he has enthusiastically embraced
the field of astrophotography and amazes me with his output
of beautiful photographs of the night sky.
Dimitri's high quality work can be seen at his website
located at Zhn Observatory
The above link is to an external web site.
 

All of the images below were taken by Dimitri using 35mm film.
