| 110°to 140°in Galactic Longitude Area Cassiopeia
The Milky Way around Cassiopeia is fine, and positioned at the most northern celestial region, the Polar Star (Polaris) is positioned at a bit upper outskirts of picture. Almost all of reddish diffused nebulae in this area are lumps of hydrogen gaseous matter emitting the H-alpha spectrum; we cannot detect those with naked eyes. And it's one of characteristics that there are plenty of open star clusters enjoyable only with binoculars around the constellation of Cassiopeia. Links to major objects Links to Constellation |
90°to 110°in Galactic Longitude Area Cepheus
This Milky Way area includes the constellation of Cepheus, continued from Cygnus in right. The Milky Way joins in here that has two flows divided by a huge dark-lane in the area of Cygnus. Though we can see the Milky Way in Cepheus looks like a single and very dimmed cloud, it's clearly that includes very complicated dark and diffused nebulae. Similar to the North American Nebula in Cygnus region, it's round nebula of IC1396 that attracts in attention of us around this area. And we can enjoy many other fine reddish breaks of clouds; it tells us that the inner-Galactic space in here is rich in the hydrogen clouds nearly equal to that around Sagittarius region.

60°to 90°in Galactic Longitude Area Cygnus
We can appreciate the Milky Way in a beautiful summer constellation of Cygnus forked into two branches. Because the dark-lane in this area is very remarkable that divides the Milky Way in Cygnus. And this dark-lane becomes more and more conspicuous as that goes to Sagittarius region. The Milky Way in this area has the most striking diffused nebula of the North American Nebula and neighbored fine clouds near Deneb (alpha Cygni). It's detectable the very dimmed and wide nebulosities just east and west of North American Nebula. It's considered that the gigantic gaseous region occupies almost half of Cygnus is a lump of hydrogen cloud scattered in the Galaxy, and the North American Nebula is an simple deep region in the vast expanse of cloud.

20°to 60°in Galactic Longitude Area Scutum & Aquila
It's very remarkable that the wide dark-lane tearing up the Milky Way in Aquila and Scutum. The dark-lane is meandering and curves gently westward (upper part in picture). And strange to say, the Milky Way in this area hardly includes diffused nebulae in spite of plenty of reddish nebulae in neighbored regions of Sagittarius and Cygnus. But we can appreciate many dark nebulae in this area through small binoculars. Links to major objects Links to Constellations |
0°to 20°in Galactic Longitude Area Sagittarius
The Galactic Longitude of zero correspondents to the center of our Galaxy, positioned at the southern region of Sagittarius. The Milky Way in Sagittarius has the widest and brightest flow in the celestial sphere and includes uncountable nebulae and star clusters. It's a pity that the Milky Way around here has the meridian transit at most about 30 degrees at Japan. And it's one of characteristic that the Milky Way in Sagittarius has not only many beautiful celestial objects but also the very complicated and highly developed dark-lanes. Especially it looks like a celestial black mesh in the western region (upper part in picture), a single flow of dark nebula is stretching to Antares, alpha Scorpii, at the upper edge of picture.
