In this astrophotography image processing tutorial, I will explain an easy way to selectively boost the colors in your image. I like to call the technique “selective color boosting“. Increasing the saturation of your deep-sky object can bring out the true beauty of your subject, and better showcase the contrasting elements of the nebula or…
Narrowband imaging involves isolating and capturing specific wavelengths of light using filters. Deep-sky astrophotography enthusiasts can produce dynamic images of objects in space through their telescope with the help of narrowband filters. The following video provides an overview of the topic of narrowband imaging and how you can create a Hubble Palette image using narrowband…
In this post, I’ll walk you through the image processing steps I used to create the image of the Andromeda Galaxy shown below.
