A new month brings a new crop of celestial wonders for astronomers everywhere to view. This September brings a flurry of nebulae and star clusters with it, meaning you\u2019ll be able to get your fill of <\/span>stars in all stages of life<\/span><\/a> this month! We\u2019ve got some of each for you to find with your <\/span>Unistellar Telescope<\/span><\/a>, including one cluster with a curiously missing centerpiece.<\/span><\/p>\n

Many of these September sights lie in the constellation Cygnus the Swan<\/strong>, which hosts a rich tapestry of deep sky objects due to its location on the galactic plane. This stellar pattern is one of the Northern hemispheres\u2019 high-in-the-sky Autumn gems, but is still visible for some Southern hemisphere observers (it will be quite low on the horizon for those at very Southern latitudes). So let\u2019s dive into the Swan and its neighbors to visit the fascinating targets that this month has to offer. <\/span><\/p>\n

Albireo<\/b><\/h3>\n

Turn your telescope to the head of Cygnus the Swan, the gleaming double star Albireo. The two stars that make up this pair appear with different colors through a telescope, as one is much hotter than the Sun and one much cooler.\u00a0<\/span><\/p>\n

Because this star is so bright, you can choose whether or not to use Enhanced Vision. If you want to see the clear separation between the stars, you may instead use the \u201cEdit\u201d button at the bottom of your live view screen to reduce the Gain and Exposure time of the image. This will allow you to better tell the stars apart. <\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

M39<\/b><\/h3>\n

Find this open cluster in the constellation of Cygnus. It\u2019s near the bright star Deneb, the tail of the Swan, which can be helpful for locating the cluster. M39 is part of both the Northern Cross and the Southern Triangle – two of the most well-known asterisms in each hemisphere!<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Cocoon Nebula\u00a0<\/b><\/h3>\n

Sitting at the edge of Cygnus the Swan, the folds of the Cocoon Nebula shelter a region of young and still-forming stars that burns brightly. Peer closely into this forge of star creation and imagine the fiery conditions within. <\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Angelfish Cluster (M71)<\/b><\/h3>\n

Visible from both hemispheres, the Angelfish Cluster in Sagitta straddles the line between an open cluster and a globular cluster. The difference between these two types of cluster is namely their age and concentration of stars – open clusters are not as dense and contain younger stars, while globular clusters contain older, densely packed stars. Scientists eventually settled on designating the Angelfish as a young, loosely concentrated globular cluster. See what you think!<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Summer Beehive (IC 4665)<\/b><\/h3>\n

Not to be confused with the well-loved Beehive Cluster of the constellation Cancer, the Summer<\/em> Beehive Cluster lies in Ophiucus. This lovely open cluster is often called Poseidon’s Trident Cluster – can you spot this familar shape?

There’s plenty of other great targets to see this month. For example, both the Fireworks Galaxy and the Veil Nebula<\/a> are primely placed in Cygnus, and other dim nebulae like the Little Ring Nebula (NGC 6894) may pose a fun challenge. Check you Unistellar app catalog to see what’s up in the sky!<\/strong><\/em><\/p>\n

Crescent Nebula (NGC 6888)<\/b><\/h3>\n

At the heart of this emission nebula, which also lies in Cygnus, you\u2019ll find a rare Wolf-Rayet star – a massive star that\u2019s been living fast and is on its way to dying hard as it burns heavier elements for fuel after it used up all of its hydrogen. This star emits strong stellar winds that whip the clouds of gas and dust in the Crescent Nebula into complex shapes. After several minutes of Enhanced Vision, you should see its half-circle structure begin to appear!<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The bluish glow of the nebula comes from a hot, massive star at the center of the nebula, named HD 200775. Blue light from the star is scattered off dust grains in the nebula, giving it its distinctive color. The dust can also be seen on the outer portions of the nebula, where it has a faint brownish color and blocks out stars behind it. It was observed in the filters B (blue), V (green), R (orange) and Hydrogen-Alpha (red).
