Amatör astronomi, mühendislik ve temel bilimler ve sosyal bilimler gibi çok farklı alanlarla ile doğrudan ilişkili olduğundan her yaştan, her meslekten insanların hayat boyu zevkle uğraşabilecekleri bir hobidir. Genelde amatör astronomi ile ilgilenmeye başlayan insanlar bilgi açıklarını çok hızlı bir şekilde kapatma ihtiyacı duyarlar. Bu noktada, doğru bir başlangıç yapmak, hayal kırıklığına uğramaları en aza indirmek açısından çok önemlidir. Bu bildiride, kurulu amaçlanan biri amatör astronomiyi halka sevdirmek ve yaymak olan Ali Kuşçu Amatör Astronomi Topluluğunun yaptığı aktivitelerden edindiği deneyimler anlatacaktır. Ayrıca topluluğun, astronominin önemli bir kolu olan astronomi fotoğrafçılığı konusunda yaptığı çalışmalar verilecektir. Bu bildirinin amaçlarından biri de, ister gözlem isterse astronomi fotoğrafçılığı konusunda olsun astronomiden beklentilerin fazla masraflara girilmeden de karşılanabileceğini ve bundan da zevk alınabileceğini göstermektir. Amateur Astronomy is a nice hobby for everyone. It is related to many branches of science such as engineering, social and fundamental sciences. Generally, first of all the person who is interested in Amateur Astronomy needs many useful information about it. The most important thing is to start in a right way. Ali Kuşçu Amateur Astronomy club was built for this requirement. The aim of our club is to help someone to love astronomy and start astronomy rightly. This paper consists of a guide for beginners and describes how to use a camera in astronomy. It is called astrophotography. This paper tells our experiences about astrophotography and shows you our photos. You can take some ideas from them. One of the aims of this paper is to show people right way to start astronomy and whatever their finance condition are, they can meet their requirements and learn Astronomy and be happy. First of all, look to the sky, see Milky Way, be happy, be curious to learn more information about astronomy.

Kapsamlı araştırma ve yıllar içindeki yayınların incelenmesiyle Amatör Astronomi’nin tanımı yapıldı. Dünya' da ve Türkiye' de Amatör Astronomi alanımda yetiştirtilen çalışmalar karşılaştırılmıştır. Elde edilen sonuçlar doğrultusunda Türkiye’deki Amatör Astronomi’nin hangi konumda olduğu belirlenerek, Türkiye’de Amatör Astronomi'yi geliştirmek adına neler yapılabileceği bu çalışmada irdelenmiştir. Definition of Amateur Astronomy has been made by doing comprehensive research and studying publications on amateur astronomy. Amateur Astronomy researches in World and Turkey were compared. In this study we focus on that what could be done in order to improve Amateur Astronomy reserches in Turkey for future generation.

We discuss various topics concerning the propagation, generation, and detec-tionof high-frequency (HF) radio waves in the Earth's ionosphere. With re-gardsto propagation, we derive a full wave Hamiltonian and a polarization evo-lutionequation for electromagnetic waves in a cold, stratified magnetoplasma.With regards to generation, we will be concerned with three experiments con-ducted at the ionosphere- radio wave interaction research facilities at Sura, Rus-siaand Tromsø, Norway. These facilities operate high power HF transmittersthat can inject large amplitude electromagnetic waves into the ionosphere andexcite numerous nonlinear processes. In an experiment conducted at the Surafacility, we were able to measure the full state of polarization of stimulatedelectromagnetic emissions for the first time. It is expected that by using thetechnique developed in this experiment it will be possible to study nonlinearpolarization effects on powerful HF pump waves in magnetoplasmas in the fu-ture.In another experiment conducted at the Sura facility, the pump frequencywas swept automatically allowing rapid, high-resolution measurements of SEEdependence on pump frequency with minimal variations in ionospheric condi-tions.At the Tromsø facility we discovered by chance a highly variable, pumpinduced, HF emission that most probably emanated from pump excited spo-radicE. Regarding detection, we have proposed a set of Stokes parametersgeneralized to three dimension space; and we have used these parameters in aninvention to detect the incoming direction of electromagnetic waves of multiplefrequencies from a single point measurement.

Üniversitelerimizin astronomi bölümleri yaklaşık 50 yıldan beri halkın astronomiye ve fen bilimlerine ilgisini ve sevgisini arttırabilmek için büyük çaba sarfetmişlerdir. Değişik alanlarda yapılan çalışmaların başında amatör astronomlara yönelik dergi faaliyetleri ve yaz okulları gelir. Bu alanda en etkin çalışmayı Ege Üniversitesi Astronomi Bölmü öğretim elemanları ve öğrencileri son 14 yıldır yüzlerce kişi yetiştirmiştir. Yaz okullarına katılan kursiyerlerin %50’sinin 18-50 yaş arasında olması, kursiyerlerin çalışmalarına rahatlıkta sürdürebilecek yaşta ve beceri de olduklarını gösterir. Bu faaliyetleri yakından izleyen amatörlerden bazıları kendi teleskoplarıyla çeşitli çalışmalara başlamışlardır. Bu çalışmaların bir kısmı dergilerde yayınlanmıştır. Yıllar süren uğraş sonucunda Amatör Astronomi Derneği de kurulmuştur. Profesyoneller, artık amatörlerin daha üretken olmasını beklemektedir. Amatörlerin gökbilimine gözlemleriyle sağlayacakları destek birçok yıldızın gizemi çözebilecektir. The astronomy departments of the universities in Turkey have made great effort in the last 50 years to increase the concern and sympathy of the public in the field of astronomy and in science as well. Puplishing some periodicals and organizing summer schools are main activities among these. The staff and the students of the Astronomy Department of Ege University have assumed a leading rolle during the last 14 years and trained hundreds of people. 50% of the participants of the organized summer schools are between 18-50 years of age and this fact indicates that they are well able to continue their work themselves. Some of the people who followed these activities have started working on various topics with their own telescopes. Some of these Works have already been publised in variouns magazines. A “society of amateur astronomers” has also been establised after a long-lasting effort. Professional astronomers are looking for more productive amateurs from now on. The support which the amateurs will provide with their observations will help in solving the mysteriouns behavior of many stars.

Johannes Hevelius (nach seinen Schriften in lateinischer Sprache, deutsch Johannes Hevel oder auch Johann Hewelcke, polnisch Jan Heweliusz; * 28. Januar 1611 in Danzig; † 28. Januar 1687 ebendort) war ein Astronom und gilt als Begründer der Kartografie des Mondes. Historischer Buchbestand der FB Astronomie der Universitätsbibliothek Wien VD17 39:125093U Informationen zu Johannes Hevelius: http://www.deutsche-biographie.de/sfz32028.html Johannes Hevelius (according to his writings in Latin, German Johannes Hevelius or Johann Hewelcke, Polish January Heweliusz; * January 28, 1611 in Gdansk, † January 28, 1687 same place) was an astronomer and is considered the founder of the cartography of the moon.

As of 1984, the submm band (ν >300 GHz) is relatively unexplored. The word “relatively” should be stressed since, evidently, a great deal of work has been done. However, much of this is of the “discovery” or “first detection” category with emphasis on the priority of a given result, and less thought as to astrophysical consequences. It therefore seems to be a useful exercise to examine what astrophysics one should expect from submm measurements. A great deal of these measurements will be the extension of work going on at longer wavelengths, and we will base much of our discussion on our own recent research and comment on its consequences for observations at frequencies above 300 GHz. (Summaries of frequency scans in the 200–260 GHz region are Erickson et al. 1980 and G. Blake, this volume.) We will emphasize the way in which observations in the various wavelength bands complement one another, and outline the connections by means of a few examples. Finally, we will present a short description of the 10-m submm dish to be built by the MPIfR and to be operated by the University of Arizona and the MPIfR on Mt. Graham, near Tucson, Arizona.
