About Peter
"As a young boy I can still recall the electrifying atmosphere in that coffee shop in the summer of 1969 as children and grownups were witnessing the events of the first Moon landing unfolding on the TV screen.

It left quite an impression that later led to the purchase of my first telescope, a 60mm refractor with which I enjoyed looking at the Moon, Jupiter and Saturn.

In a way I was quite lucky as our high school housed a small professional observatory with an equatorially mounted refractor and two wide field instruments, their main purpose to monitor the trajectories of the first Sputnik satellites.
Peter Karboulonis.
It was there that for the first time that I was introduced to imaging the Moon and planets on film using SLR cameras.

Since then I have owned and used several telescopes, dedicated astronomy cameras, video cameras and DSLRs. The articles in this section incorporate much of what I have learned during this process, I sincerely hope that you find the articles interesting and useful. "
