In this tutorial, Ron Brecher, Co-Founder of Masters of PixInsight, introduces the new automatic cosmetic correction feature in the Weighted Batch Pre-Processing (WBPP) script. This enhancement simplifies the removal of image defects such as hot pixels and bad columns. Key points include:

Introduction to Cosmetic Correction:
- Learn about the three modes: using a master dark, auto-detection, and defect lists. Ron explains how auto-detection can complement master darks for thorough pixel correction.

Using Auto Cosmetic Correction in WBPP:
- Discover how to enable automatic cosmetic correction without pre-defined templates, provided you have a master dark loaded. Adjust pixel thresholds to customize the correction strength.

Practical Tips for Calibration:
- Explore Ron’s recommended settings for hot and cold pixel removal and how to inspect corrected frames for optimal results.
