From the noticeable constellations of the autumn sky in the eye catches the characteristic circus of Perseus, a chain of bright stars Andromeda, and, of course, the famous square of Pegasus. A tiny chain of stars - a small constellation of the Lizard - appeared above them. Just below Andromeda is a small constellation of the Triangle, just below the Aries, and quite below the vast constellation of Kit. Just under the winged horse are the two remaining heroes of our review - a dim but extended constellation of Pisces and Aquarius, which should be looked for not from the square of Pegasus, but from another prominent star of this constellation - Pegasus epsilon.
We will begin with the constellation of Perseus, whose figure resembles a walking man, rises in our latitudes highest in the autumn months. The Perseus constellation, which occupies an area of 615 square degrees in the sky, contains 90 stars visible to the naked eye. In Perseus, there are quite interesting objects for amateur instruments, the main of which is certainly a bright pair of scattered clusters of Hi and Ash Perseus, accessible even to the naked eye. There are also variable stars and several double stars in the constellation, numerous scattered clusters, planetary nebulae, there are even galaxies, a small device is available to one of them. The constellation also contains the radiant of the meteor shower of the same name (Perseids).
To the west of the Perseus constellation stretches to the square of Pegasus a characteristic chain of bright stars - a constellation of Andromeda. Andromeda Square is even larger than its neighbor - 722 square degrees, 100 stars brighter than the sixth star. In the constellation is the brightest (and most famous) of the galaxies in the northern sky - M31 "Andromeda Nebula", visible to the naked eye. Andromeda also has a lot of scattered star clusters, a few more dim galaxies, double stars, and a planetary nebula.
Just below Andromeda, a small constellation formed by the characteristic dim shape of the stars - a triangle. The triangle occupies an area of only 132 square degrees in the sky and contains only 15 stars visible to the naked eye. Nevertheless, there is one more bright galaxy of our sky - M33. Its luster lies at the limit of visibility of the eye, so you need a very dark and clear sky to find this galaxy without optical devices.
Even lower, under the triangle, are the constellations of Aries. It is also not very large in size - 441 degrees, however, it contains 40 stars up to the sixth-star size. In Aries, there are interesting double galaxies, a pair of galaxies available to medium tools.
Just beneath Aries, there is the constellation of the Keith. By area it is one of the most extensive constellations - 1230 square degrees, contains hundreds of stars available to the naked eye. In Keith, there is the famous long-periodic variable omicron Keith - Mira, which is named after this class of variable stars - Merida. In Keith, there are also several more variables and double stars, a couple of galaxies available to small devices.
To the west of Andromeda, we will find a bright square of the Pegasus constellation. In the Pegasus of the foggy objects, there is a bright star cluster, a pair of galaxies available to small amateur instruments, several interesting double ones. Pegasus Square is a large constellation and occupies 1121 square degrees. There are hundreds of stars visible to the naked eye.
Just above the Pegasus, there is a small chain of bright stars - the constellation of the Lizard. This is another of the small constellations of our sky - 201 degrees in the sky. 35 stars are visible to the naked eye in the Lizard. It contains several very weak double stars and one scattered cluster of stars.
Just below Pegasus, the constellation of Pisces stretches. Its area is quite large - 889 square degrees, 75 stars brighter than the sixth-star size. There are several interesting double stars in Pisces, a couple of galaxies available for small instruments, and also a point of vernal equinox in this constellation.
And finally, the last hero of our autumn walk is located even below Pisces and Pegasus - the constellation of Aquarius. In Aquarius there are 90 stars visible to the eye, the area is quite large - 980 degrees. In the constellation, there are many objects available to the amateur device: a couple of bright ball clusters, a couple of nebulae, a few curious double stars. In Aquarius, there are radiants of three rather bright meteor streams.
