Polaris - North Star - Kutup Yildizi
From our garden this photo of the constellations Ursa Major and Ursa Minor was taken. The coordinates of our garden are 41.53 deg North, 27.36 deg East in Luleburgaz, a township in Northwest Turkey. The North Star is a member of Ursa Minor and is the closest star to the celestial North Pole. Exposure time of the image is 142.9 sec and I set the focal length to 18 mm so I could cover as large an area as possible. It was a moonless dark sky with small cloud clusters. You can see the stars rotating about the Pole Star. The arc of the star traces can be calculated as 143.9*360/86400 = 0.6 degree. I wish I could keep the exposure time longer in which case you would see larger stellar circles. I didn't do that because I wanted you to recognize the Ursa Major and Ursa Minor. The color of the trees are due to the feeble background light being reflected by them. I didn't do any photo editing except for putting my signature and compressing the image for shorter upload time to Flickr.
Buyuk Ayi ve Kucuk Ayi takim yildizlarinin bu resmi bahcemizden cekildi. Bahcemiz Luleburgaz'in Celaliye koyunde ve koordinatlari 41.53 derece Kuzey, 27.36 derece Dogu. Kutup Yildizi Kucuk Ayi takim yildizlarindan olup astronomik kuzeye en yakin olan yildizdir. Fotografin poz muddeti 142.9 san, odak uzakligi ise 18 mm. Yildizlarin Kutup Yildizi etrafinda donmeleri belli oluyor. Yukaridaki hesapla her bir yildiz 0.6 derecelik bir yay uzerinde hareket etmis durumda. Poz suresini uzun tutsaydim daha buyuk yaylar gorecektiniz, ama yildizlari tanimak zorlasacakti. Fotograf aysiz ve karanlik bir gecede cekildi. Agaclarin goruntusu ve rengi cevreden gelen isiklarin yansimasinin 143 saniyedeki birikimi. Uzun poz muddetinden dolayi agaclar biraz da flu cikmis.
