together with beta star merak below, the two form a line pointing the way to polaris and the north celestial pole off the top edge of the field.
她和下面的北斗二天璇组织的直线指向上方的北极星和北天极。
polaris is famous as the north pole star, a friend to navigators and astrophotographers alike, but it's not located exactly at the north celestial pole (ncp) either.
北极星以其乃北极之星而闻名,是导航员和天体照相学家们的好朋友,不过它其实并不是正对着北天极(ncp)。
towards the middle of the above digitally stretched picture is the north celestial pole (ncp), easily identified as the point in the sky at the center of all the star trail arcs.
这张数码合成照片的中心位置是北天极,作为天空中所有星迹圆弧的中心点,北天极很容易找到。
