Image processing is the process of editing digital images using computer software to improve their quality and enhance their visual appearance.
This is an important part of astrophotography because the human eye is not capable of seeing the details captured in a deep-sky long exposure photograph.
By processing your images, you can pull out all the faint details hidden in the data that you captured during your imaging session.
If you are a beginner and looking for something to help you through the entire process from start to finish be sure to purchase my Astrophotography Image Processing Guide.
In the following articles, you’ll find useful tutorials to help you get the most out of your image data using DeepSkyStacker, and Adobe Photoshop.
Last updated: November 4, 2025. If you find this helpful and buy through my links, I may receive a small commission. My latest photo of the Andromeda Galaxy is my best effort yet. I have been taking deep-sky astrophotography images for almost 15 years now, and this might be my favorite photo of space I’ve…
Last Updated September 9, 2025 Choosing the right computer for image processing can save you a lot of headaches when you’re trying to process those jaw-dropping images of the night sky. Applications like Adobe Photoshop and PixInsight can really push a computer to its limits when processing astrophotography images, so what kind of specs do…
The best way to reduce noise in astrophotography is to improve your signal-to-noise ratio by taking more pictures. By taking multiple exposures and stacking your images to average out random noise, you can dramatically improve your astrophotography images. You can further improve your final image data by taking calibration frames to remove sensor artifacts and…
In modern astrophotography image processing, software tools are evolving faster than ever. One that’s been generating a lot of buzz in the deep-sky community is the Seti Astro NB to RGB Star Combination Tool. This utility bridges the gap between narrowband and RGB star data, making it easier than ever to create natural-looking deep-sky images…
I recently ran an impromptu astrophotography image processing challenge, and the results were out of this world (sorry, I had to do it). The craziest thing about it is that the data wasn’t overly great (in terms of overall exposure time) or interesting. Just a seemingly random portion of the constellation Cygnus that includes the…
I’ve recently been made aware of the Seti Astro Statistical Stretch standalone tool for astrophotography image processing. This is a simple and free tool you can use as a part of your image processing workflow that I think you will find very handy. Frank is an extremely generous developer and amateur astrophotographer who has released…
In this article, I will share my latest wide-field astrophotography processing tutorial using star removal and advanced stretching techniques. Wide-field astrophotography opens up stunning views of the night sky, capturing vast regions of stars, nebulae, and constellations. In this guide, I’ll walk you through a game-changing technique to enhance your wide-field images using tools like…
This article was last updated on December 4th, 2024. In this post, I’ll break down how to photograph the Orion Nebula, one of the most spectacular deep-sky objects in the night sky. While it may just look like a smudge to the naked eye, Orion is the nearest, large star-forming region to Earth at just…
There is nothing like taking your first deep-sky astrophotography image. You’re taking pictures of objects that lie thousands or millions of light-years away. Galaxies, nebulae, and star-forming regions are out there, and there’s an endless supply of new targets to capture. The best part is that you can see way more in an image than…
As an astrophotographer myself, I am constantly learning new image-processing tips and tricks from the astrophotography community. My absolute favorite way to learn is by watching YouTube videos created by knowledgeable people willing to share what they have learned. I have recently discovered Paulyman Astro, who is a fantastic resource for all things PixInsight. He…
I’ve been enjoying Russ Crowman’s (RC Astro) astrophotography processing tools since his release of GradientXTerminator many years ago. Now, one of his most popular astrophotography image processing tools has received an impressive upgrade: BlurXTerminator 2.0 AI Version 4. While I am excited to use and share my experiences with this handy new tool myself,…
A great astrophotography image is very subjective. What some people would consider to be the ‘perfect’ image, is a complete mess to others. While there are some core aesthetics that I think most people can agree on (nobody likes a noisy image), other aspects have vastly different opinions depending on who you ask. If…
