M45 The Pleiades 9 Panel Mosaic

Messier 45, the closest of any of the 110 Messier objects. It is located in the constellation of Taurus, 444 light years away, visible with the naked eye.

 

I took this over 7 nights from Sept 15-Dec 12, 2023

I have been trying longer subframes with the Hyperstar, outside of the 30sec I have been stuck on for years. Each panel has a minimum of 20 frames at 120 seconds through an Optolong LUM filter. I'm starting another round hoping to double them by the end of the season
