PixInsight Full Tutorial | HA-RGB | Step-by-Step | Photoshop Tips

Ever wondered how to process your Astro pictures in Pixinsight? And how to integrate your narrowband (Ha) with broadband (RGB) pictures? In this comprehensive Pixinsight tutorial, I offer a step-by-step walkthrough covering the entire process, from stacking and pre-processing your images in a linear state to post-processing in a non-linear state. The tutorial encompasses tasks such as creating stacked images in Pixinsight, addressing urban light pollution (color gradients), performing color calibration, reducing noise, generating a starless image, and seamlessly integrating RGB color images with Ha narrowband pictures. Towards the conclusion of the video, I also provide insights into the final integration process using Photoshop.

PixInsight, the advanced astro-processing tool, takes center stage in this tutorial tailored for those of you who already boast some astrophotography experience. You should be well-acquainted with light frames, calibration frames, and the art of stacking astro-pictures.
