What time of year can you see the Pleiades?
November
You can see the Pleiades between October and April, but the best month to look for it is November, when it can be seen for the entire night. To find the Pleiades, first locate the three stars in Orion’s Belt. During November, look above the eastern horizon from around 10pm.
How long do you have to be exposed to Pleiades?
From our experience, taking a photo with an exposure of about 3 minutes is enough to see the reflection nebulae around the stars. It of course helps if you are under a beautiful dark sky, but the Pleiades are very bright and you should be able to get great results even from the city.
How far away is Alcyone?

What is the accepted value for the age of the Pleiades?
This can be taken as the maximum age of the Pleiades. (The accepted value is 50-100 million years.)
What months are the Pleiades visible?
Watch for the cluster in spring and summer. They are visible from about October to April, during the Southern Hemisphere’s spring and summer months. Face the northern sky. During late November, the Pleiades rise in the northeast around dusk and travel west until dawn.
How do you photograph Pleiades?
Camera Settings and Tips
- Use a “fast” aperture of F/2.8 – F/4.
- Set your white balance setting to daylight.
- Use manual mode.
- Set exposure length at 30 seconds.
- Shoot in RAW image format.
- Use an ISO of 400-1600 (or more)
How old is the light from Pleiades?
about 115 million years
Due to lithium’s very low ignition temperature of 2.5 × 106 K, the highest-mass brown dwarfs will burn it eventually, and so determining the highest mass of brown dwarfs still containing lithium in the cluster can give an idea of its age. Applying this technique to the Pleiades gives an age of about 115 million years.
What is the meaning of Alcyone?
the brightest star
: the brightest star in the Pleiades.
How old is NGC 188?
age determination 5 billion years old, and NGC 188 in Cepheus is 6.5 billion years of age. The oldest known open cluster, Collinder 261 in the southern constellation of Musca, is 8.9 billion years old.
What degree of Taurus is Pleiades?
In the northwestern quadrant of the Taurus constellation lie the Pleiades (M45), one of the best known open clusters, easily visible to the naked eye. The seven most prominent stars in this cluster are at least visual magnitude six, and so the cluster is also named the “Seven Sisters”.
Where is Alcyone located in the Pleiades constellation?
Alcyone is located in the shoulder blade of Taurus (the bull) constellation. It is the main and biggest star of the Pleiades or Seven Sisters and in fact, its name means “the Central One.” Because these stars are all situated within one degree of one another, Alcyone is often times used to represent the entire group.
What kind of star is the Alcyone star?
Alcyone is a Be star and, like all the named Pleiades except Maia, it is a very fast spinner, with a projected rotational velocity of 149 km/s. As a result, it is surrounded by a disk of gas ejected around the equator. The nearest companion is a low-mass star separated by less than 1 milliarcsecond from the primary.
Which is the brighter star Alcyone or Maia?
Of all the Pleiades stars, Alcyone shines 1,000 times more luminous. At one point Maia shone brighter than Alcyone, but that is no longer the case; Alcyone is 1,000 times more luminous. Some say it represents sibling rivalry.
Which is the brightest star in the Pleiades?
The Moon and the Pleiades 2021 to 2025 The Pleiades cover 29 Taurus to almost 1 Gemini – Alcyone is the brightest star in the Pleiades. The Moon moves 1 degree about every two hours so will pass all the stars of the Pleiades in about 6 hours. Moon with Pleiades/Alcyone 2021
