M45 - Pleiades closeup (Merope & Alcyone)


Pleiades, in Greek mythology, the seven daughters of the Titan Atlas and the Oceanid Pleione: Maia, Electra, Taygete, Celaeno, Alcyone, Sterope, and Merope. They all had children by gods (except Merope, who married Sisyphus). The Pleiades eventually formed a constellation.
In this closeup 800mm focal length Merope and Alcyone are the highlights.

This image is just 20 minutes of data (120x10s) taken on a OnStep converted CG5-ASGT mount carrying a hefty F4 800mm GSO scope and the ASI 533. unguided.
