M45 “Pleiades” Open Star Cluster

This image of the Pleiades open star cluster and associated reflection nebulosity was taken over 8 nights in 2026, and was first light for my SQA55 quintuplet refractor telescope. I used a UV/IR filter instead of my usual light pollution filter to try and capture as much faint dust and nebulosity as possible. The camera used was a ZWO ASI533MC Pro.
