In this free tutorial, Alexander Curry, Co-Founder of Telescope Live, explores the importance of choosing the right file formats for saving and sharing astrophotography images. He discusses the differences between common formats like FITS, TIFF, PNG, and JPEG, and how they impact image quality and usability. Key points covered include:

XISF to TIFF Conversion:
-Learn how to convert XSIF files to TIFF using PixInsight’s batch processing tool, preserving resolution and detail across software.

TIFF for Post-Processing:
-Understand why TIFF is the go-to format for retaining high-quality data during post-processing and adjustments.

PNG vs JPEG for Sharing:
-Compare PNG and JPEG formats, noting the loss of detail with JPEG due to compression, and how each format is suited for different platforms, such as social media or personal sharing.

This guide ensures you make the most of your astrophotography data, from editing to sharing your final image.
