In this tutorial, Telescope Live tutor Nik Szymanek introduces the latest version of GraXpert, a free AI-powered tool for astrophotographers. Nik demonstrates how to process a dataset of NGC 660 using GraXpert’s intuitive workflow, including gradient correction, deconvolution, and denoising. Key steps include:

Interface Overview and Setup:

- Install GraXpert, download required AI models, and prepare your image with basic cropping to remove dithering artefacts.

Gradient Removal with AI Background Extraction:

- Use the AI mode for a simplified alternative to PixInsight’s DBE, with sigma and saturation controls for fine-tuning.

Deconvolution and Denoising:

- Apply AI-based deconvolution and denoising with recommended starting values, using preview modes to compare results.

Saving and Exporting:

- Save the final image in 32-bit FITS or 16-bit TIFF format, optionally retaining the applied stretch for further editing in Photoshop or Affinity Photo.

Nik’s walkthrough shows how GraXpert can streamline core astrophotography tasks with minimal complexity.
