Hayades Star Cluster with Aldeberan
I'm finally getting the hang of using the Star Adventurer Mini (SAM). On this shot of the Hyades Star Cluster I was able to keep the polar alignment in place and keep the focus from drifting out resulting in a nice sharp image. I shot this at f/4 so there is no 'shuttlecock' look to the stars. The bright, reddish star is Aldeberan, not part of the Hyades Cluster but clearly visible when looking tawards the Hyades.
The Hyades (also known as Melotte 25 or Collinder 50) is the nearest open cluster and one of the best-studied star clusters. Located about 153 light-years away from the Sun, it consists of a roughly spherical group of hundreds of stars sharing the same age, place of origin, chemical characteristics, and motion through space.From the perspective of observers on Earth, the Hyades Cluster appears in the constellation Taurus, where its brightest stars form a "V" shape along with the still brighter Aldebaran. However, Aldebaran is unrelated to the Hyades, as it is located much closer to Earth and merely happens to lie along the same line of sight.
The five brightest member stars of the Hyades have consumed the hydrogen fuel at their cores and are now evolving into giant stars.Four of these stars, with Bayer designations Gamma, Delta 1, Epsilon, and Theta Tauri, form an asterism that is traditionally identified as the head of Taurus the Bull.The fifth of these stars is Theta1 Tauri, a tight naked-eye companion to the brighter Theta2 Tauri. Epsilon Tauri, known as Ain (the "Bull's Eye"), has a gas giant exoplanet candidate, the first planet to be found in any open cluster.
The age of the Hyades is estimated to be about 625 million years. The core of the cluster, where stars are the most densely packed, has a radius of 8.8 light-years (2.7 pc), and the cluster's tidal radius − where the stars become more strongly influenced by the gravity of the surrounding Milky Way galaxy − is 33 light-years (10 pc). However, about one-third of confirmed member stars have been observed well outside the latter boundary, in the cluster's extended halo; these stars are probably in the process of escaping from its gravitational influence.
