The Pleiades (Messier 45) is an open star cluster 450 light years away in the constellation of Taurus. Stars in the cluster formed around 100 million years ago. The reflection nebula was once thought to be formed from leftover material from the formation of the cluster itself. It is now believed to be a dust cloud that lies between us and the cluster, and through which the cluster's light passes.

M45 was photographed between 26 September and 24 November 2019 from a remote imaging rig that is jointly owned and operated by Barry Wilson and me. This is a two panel mosaic.

Capture details are as follows:

Telescope: Takahashi FSQ 106

Blue: 55 x 300s

A total of 24 hours and 35 minutes exposure.

I found some 'anomalies' that I should have picked up on earlier. Apologies for the multiple versions today.
