Your guide to astrophotography

Many astrophotography workflows often recommend removing stars to simplify image processing. Without stars, you are able to focus your attention on the nebula and galaxies. However, the process of star removal can often remove some of the finer details within your image. This is why star removal is often completed early on in the astrophotography workflow.

But an interesting question often arises: Should I run deconvolution before or after I remove the stars?

As astrophotographers, we constantly strive to capture the beauty of the cosmos in our images, revealing the intricate details of distant galaxies, nebulae, and celestial wonders. But noise is an inevitable companion in astrophotography, often emerging as an unwanted pixels, marring the clarity and precision of our celestial images. Whether you are grappling with thermal noise, readout noise, or the notorious “grain” in your long-exposure shots, TGV Denoise (Total Generalized Variation Denoise) offers a solution to suppress the noise while highlighting the true beauty.

TGV Denoise employs a unique approach that goes beyond mere pixel-level processing. It takes into account the broader context of the image, understanding the relationships between pixels and preserving the fine details while effectively reducing noise.
