볼록한 반달 모양의 금성입니다. 시상이 최악이었지만 테스트할 사항이 있어서 촬영했습니다.

Jupiter reaches opposition, June 11 (KST)
6월 11일 목성의 충, 최대 밝기: -2.6 등급.

http://cometsky.com/astronews/jupiter_opposition_20190610_bsyeom.jpg

Jupiter (-2.6 mag) reaches opposition and peak visibility June 11 (KST).
Opposition means that Jupiter lies closest to Earth and appears largest when viewed through a telescope. The planet’s disk spans 46".  Opposition time: June 11, 00:14(KST), Apparent size: 46.0 arcsec, Distance: 640.9 million km (4.284 AU, 35.63 light min). 

목성이 충일때 목성은 지구와 가장 가깝게 위치해 있고, 망원경을 통해서 보았을 때 가장 크게 나타납니다. 
즉, 목성의 관측 최적기. 목성의 충 시간: 6월 11일 00:14(KST), 시직경: 46”(arcsec), 거리: 6억 4090만 km (4.28 AU). 

초저녁 무렵 남동쪽 하늘에서 한층 밝게 빛나는 목성이 6월 11일에 뱀주인(땅꾼) 자리에서 충에 도달합니다. 
목성은 -2.6등급으로 밝게 빛나고 있기 때문에 육안으로도 쉽게 찾을 수 있습니다. 
목성의 오른쪽에 전갈자리의 붉은색 별인 안타레스도 볼 수 있습니다.
올해 목성 최적기는 6월까지이며, 관측하기 좋은 시기는 대략 8월까지입니다.
