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.

Venus in daylight.

한낮의 금성.


304mm Refractor + Galaxy Note 8 smartphone.

November 10, 2018 KST.


스마트폰으로 망원경의 아이피스에 대고 촬영한 금성. 

금성이 그믐달 모양으로 보이네요. 시직경도 약 1분 정도로 큽니다. 

테스트로 스마트폰으로 찍고 난 후에 행성용 카메라로 제대로 찍으려고 하니 구름이 몰려와서 촬영을 마무리했습니다.
