Algieba (Gamma Leonis), Vantaa, Pähkinärinne

Two stars are very rarely observed here in the Sky Watch, even though they look pretty nice. The moon was nicely close to Regulus and Algieba yesterday, so at the end of a great lunar observation, I still wanted to explore the often-forgotten great double star, Gamma Leon aka Algieba, the lion's neck star (Algieba means lion's crest).

With a 10x eyepiece at 150x magnification, the star was already clearly visible in two, quite close pairs. At 250x magnification, it already clearly distinguished the difference in the size of the stars. In the most handsome double stars, like Albireo, the colors also stand out perfectly, this pair looked the same color, or more or less white in the telescope.

While in the south, this pair of stars appear on top of each other, now the Lion was already in the southwestern sky in the descending direction.

In the drawing (Figure 1), the binary star as it appeared in my telescope in this direction with an angular prism. Figure 2 map image of the time of the Stellarium.
