M45 — The Pleiades
This is my first time processing this Pleiades image outside the Seestar, using PixInsight and Photoshop to bring out the blue reflection nebulosity in the captured data.
Captured with my Seestar S50 from my backyard in Round Rock, Texas, on August 12, September 24, and September 28, 2025. IR-cut filter, gain 80.
This is a mosaic combining 685 exposures: 671 × 20 seconds and 14 × 30 seconds, for 3 hours, 50 minutes, and 40 seconds of total capture time. Exposure coverage varies across the mosaic, so each part of the image received a different amount of integration.
August 12: 7 minutes
September 24: 2 hours, 27 minutes
September 28: 1 hour, 16 minutes, 40 seconds
Processed with separate star and nebulosity stretches, background correction, color balance, and noise reduction.
