Summary

This tutorial from Ciel & Espace demonstrates how to use the free software Autostakkert! for planetary astrophotography. The presenter, likely an experienced astrophotographer, walks through the entire workflow: opening videos, setting color matrix for color cameras, placing alignment points, adjusting quality estimation parameters, and stacking images. He explains the importance of alignment point size and the multi-scale option for better turbulence correction. He also covers the ‘quality estimator’ parameter, which blurs images for noise reduction, and recommends values based on camera type. The video shows how to use the analysis graph to select the percentage of frames to keep, balancing quality and signal-to-noise ratio. He demonstrates the process on Jupiter and the Moon, including a comparison between a single raw frame and the final stacked image. He also mentions the ‘RGB align’ feature to correct atmospheric dispersion and the ‘drizzle’ option for higher resolution. The tutorial concludes with a brief mention of post-processing in Photoshop or AstroSurface, and encourages viewers to consult the special issue of Ciel & Espace for more details.
