AstroPics Lab 3.1 Beta Tutorial – Full Linear Workflow, Processing tips & Community Upload

In this tutorial I walk you through AstroPics Lab 3.1 Beta, a Windows app for processing astrophotography images with AI. We go from a raw linear FITS/XISF stack to a finished image, and then share it straight to the AstroPics Community gallery. What’s new in 3.1 Beta • Full linear workflow: gradient removal, color calibration, AI denoise and AI star separation, all before you stretch • AI Separate (Linear): split stars and nebula in linear data, then stretch both layers together. Recombining them always gives back your original image • Interactive stretch panel: MTF or GHS, with a live histogram and draggable markers • “Help me process” assistant: it suggests the processing steps based on your image and target type • Faint Signal Boost (experimental): gently brings out faint halos and IFN without boosting the noise • Upload to AstroPics Community: publish your image in one click, with object, equipment, filters and processing steps filled in automatically from your FITS header • XISF support and many fixes and improvements 00:00 Start 00:46 FITS processing 16:07 Process Starry and Noisy Nebula 28:39 Process image with gradient and background problems 33:48 Add detail, change color, retouching image 48:39 Automatic process with assistant 52:34 New community website connected to Astropics Lab
