M 45, the Pleiades open cluster, is a 45-minute RGB exposure with a Takahashi FSQ-106ED 106/382 f 3/6 telescope, QHY 600M camera. It's just 9 shots, including 3×300 seconds with an R filter, 3×300 seconds with a G filter, and 3×300 seconds with a B filter. I processed them with Pixinsight and Photoshop. All data and shots were acquired with Telescope Live.
