   The name "Sandra" was given to a star of the 10th magnitude in the Perseus constellation.
     ...This is a beautiful constellation entirely located in the Milky Way to the north-east of Andromeda. It occupies an area on the sky of 615.0 square degrees and includes 153 stars visible to the naked eye. Each year in the middle of August Perseids meteor shower is observed. It is caused by particles lost by periodic Swift - Tootle's Comet. This is a Northern Hemisphere constellation and it contains the double star clusters x and h of Perseus, the alpha star of Perseus - Mirfak, the beta of Perseus - Algol.
First of all, find the North Star, and then Cassiopeia constellation. Put out your hand, spreading the thumb and the forefinger on the maximum possible angle. This angle is about 18 į. Now move your forefinger on the Cassiopeia, and put the thumb perpendicularly downwards.
You will see the stars belonging to Perseus constellation there.
     Compare the observed stars with a fragment of the star map and remember the location of Perseus constellation. After that pay your attention to the long chain of stars, stretching from Perseus in the direction of the south point. This is Andromeda constellation. If you draw an imaginable line from the North Star through Cassiopeia, this line will also point to the central part of Andromeda.
     For comfortable viewing you will need glasses with not less than 10-fold amplification or a telescope with a diameter not less than 5cm.
