Prima actiune / First ''International Sydewalk Astronomy Night''


I found on my computer my note about the first  ''International Sydewalk Astronomy Night'' which took place on the 19-th of May 2007.
This action was organised by ''sydewalkastronomers'' in USA and it was attended by amateur astronomers and public  world wide.

Apart of ''Galaxis Club'' in Arad ,the first ISAN was attended in Romania  by AREA/ ''Romanian Assoc. for Education in Astronomy'' of Arad, Astronomical Association ''Sirius'' of Barlad, a member of the ''Meridian 0'' in Oradea ,the Astronomy Club of Bucharest  and Octavian Georgescu.
More details on the ISAN site :

Below one may see the content of the poster of  our ISAN action in Arad,sponsored by  ''Galaxis Astronomy Club'' and ''Pro Mixdesign'' , a  private company pioneering the local commerce of astronomical equipment.
General public here show little interest in Astronomy.
However this company was trying the trade of astronomical equipment because one of the shareholders was Farkas Laszlo ,a professional astronomer at the Astronomical Observatory in Timisoara.

“ International Sydewalk Astronomy Night “este  o actiune  in care   publicul  observa  corpurile ceresti prin telescop.
Actiunea este si  un omagiu adus lui John Dobson ,inventator al telescopului care –i  poarta numele si care a declansat revolutia dobsoniana in Astronomia de amatori.
John Dobson a propus de mult timp ca, in aceeasi noapte, o mie de telescoape sa fie scoase in strada in lumea intreaga pentru ca” milioane de oameni sa vada , pentru ca  milioane de oameni sa inteleaga”.

Dobson si telescoapele sale pentru amatori/Dobson and his telescopes for amateurs

I published the following article in the  ORION'' magazine, year X ,number for May-June 1993, courtesy of comrades of astronomy hobby from  Bucharest Astronomy Club.
The 160mm telescope at F/9.2, mentioned in the article and built around an excellent Beches mirrors, is the one which appears in the title page of my blog.
False modesty aside, I think this was  the first of its kind built in Romania and my modest article is the first Romanian plea for the virtues of this popular telescope.
Dobson telescope was and remains the type of telescope that allows the easiest access to large apertures or the type of mount  most easily built at any aperture.
Congratulations to each ATM-er and user of these wonderfully simple and efficient telescopes,  with my  wishes for clear sky and wonderful stellar  views!
And do not forget, from time to time, to remember with a shred of gratitude of John Dobson!
Thank you John Dobson!

Am publicat  articolul de mai jos in revista ''ORION'' ,anul X , numarul din Mai-Iunie 1993, prin bunavointa camarazilor de hobby astronomic de la Astroclubul Bucuresti.
Telescopul de 16cm F/9.2, pomenit in articol si construit in jurul unei excelente oglinzi Beches ,este cel care apare in pagina de titlu a blogului  meu.
Lasand la o parte falsa modestie,cred ca telescopul cu pricina este primul de acest fel construit in Romania iar modestul meu articol este  prima pledoarie pe meleagurile noastre pentru virtutile acestui telescop popular.
Telescopul Dobson a fost si ramane in continuare tipul de telescop care permite accesul cel mai usor la aperturile mari sau este tipul de montura cel mai usor de construit la orice apertura.
Felicitari fiecarui constructor si utilizator al acestor minunat de simple si eficiente telescoape,odata cu urari de cer senin si minunate privelisti stelare!
Si sa nu uitam ,din cand in cand,sa ne amintim cu o farama de recunostinta de John Dobson!
Multumesc John Dobson!
