Castor A and B.

카스토르 A와 B.


Castor A and B.

Castor is the second-brightest object in the constellation of Gemini and one of the brightest stars in the night sky. It appears singular to the naked eye, but it is actually a sextuple star system organized into three binary pairs. Castor is a multiple star system made up of six individual stars; there are three visual components, all which are spectroscopic binaries. The apparent magnitude of Castor A, B, and C stars is +1.9, +3.0, and +9.8.


카스토르 A와 B.

카스토르(Castor) 쌍둥이자리에서 두 번째로 밝은 별이며 밤하늘에서 가장 밝은 별 중의 하나이다. 카스토르는 맨눈으로는 하나의 별로 보이나 사실은 3개의 쌍성으로 이루어진 6중성계이다. 또한 이들 3개의 쌍성은 각각 분광 쌍성이다. 카스토로 A, B, C의 겉보기 등급은 각각 1.9, 3.0, 9.8등급이다. 따라서 카스토르 C를 A, B와 같이 촬영하는 것은 어렵다.

The Winter Triangle is a prominent winter asterism formed by three stars prominent in the winter sky. The three stars that compose the Winter Triangle are Sirius (Canis Major), Procyon (Canis Minor), and Betelgeuse (Orion).


겨울철 대삼각형을 이루는 3개의 별은 시리우스(큰개자리), 프로키온(작은개자리), 그리고 베텔게우스(오리온자리) 입니다.

엷은 구름이 계속 껴 있는 상태라서 투명한 하늘은 아니었지만 그래도 사진이 나름대로 잘 나왔네요. 날씨 좋은 날에 다시 촬영해야겠습니다.

The Winter Hexagon, also known as the Winter Circle, is a prominent winter asterism formed by seven stars prominent in the winter sky. The six stars that compose the Winter Hexagon are Sirius (Canis Major), Rigel (Orion), Aldebaran (Taurus), Capella (Auriga), Pollux (Gemini), and Procyon (Canis Minor). Sirius and Procyon are also part of the Winter Triangle, a smaller asterism that these two stars form with Betelgeuse in Orion.


겨울철 육각형을 이루는 6개의 별은 시리우스(큰개자리), 리겔(오리온자리), 알데바란(황소자리), 카펠라(마차부자리), 폴룩스(쌍둥이자리), 프로키온(작은개자리)입니다. 또한 시리우스, 프로키온, 그리고 베텔게우스는 겨울철의 대삼각형을 이루는 별들입니다.


cf. 촬영 당일에 구름이 왔다갔다하는 상황이라 별자리와 겨울철 은하수가 선명하게 나오지는 않았네요. 14mm로 촬영한 이 사진은 주변부를 약간 잘라냈습니다.

Gemini (Constellation). 쌍둥이자리. Test image.


https://t1.daumcdn.net/cfile/tistory/21542E43585FD60C22?original


Gemini is one of the constellations of the zodiac. It was one of the 48 constellations described by the 2nd century AD astronomer Ptolemy and it remains one of the 88 modern constellations today. Its name is Latin for "twins," and it is associated with the twins Castor and Pollux in Greek mythology. -Wikipedia.
