Sun In Ha


Fred Ley

These four images were taken at the National Observatory of Athens in 1972. At that time a 10-inch (25cm) Ha telescope built by Razdow Laboratories in New Jersey, U.S.A., was operating in the dome of the old observatory on the Hill of Nymphs in Athens. This was a NASA project in support of the Project Apollo program. A world wide 24-hour watch on the sun maintained for purposes of monitoring solar storms that might be hazardous to the astronauts. The telescope currently resides at the Pendeli Astronomical Station of the National Observatory of Athens.

Thanks for sharing Fred, our star in Ha is always stunning and mesmerizing. If Im not mistaken, this scope in particular has never been exposed to the public and I really wonder why.

Certainly, viewing through this massive instrument would be an overwhelming experience for school students and solar enthusiasts as well.

Anyway, great pics and I'm looking forward to an active Sun like this sooooon.. (I mean when my Lunt finally arrives!)

Vangelis,

 

It has been many years since I last looked throught the telescope. Initially, I used to go up to the observatory in Athens and spend the whole day with the U.S. Air Force personnel that then operated the instrument. When they moved to Pendeli, I went up there on rare ocassions due to the distance. When the project was canceled, the Air Force gave the telescope and the radio telescope, both at Pendeli, to the observatory. It is quite possible that the instrument is currently being used for research, which may prevent public access, or it may have some broken components and sits dormant. With the Razdow company long out of business, it may hard to find replacement components. There are two images of the telescope at this location on my web site, http://www.instrumentsoflight.com/athens1.html You will need to scroll down the page towards the end to see it.
