In this article I'll show you how to improve the contrast in dust lanes in galaxies and dark features in nebulae. The article uses an image of the Pacman nebula taken from a Bortle 8 sky (very light polluted) I explain the process in a way that can be applied to most image processing packages.

In this video I'll take you through the steps to reduce noise from your images, I demo the approach in Photoshop but the approach should also work in GIMP.

In this guide I'll show you how to remove sky gradients from astro-images. The process can be applied using most imaging software, I'll talk through the theory of the approach and then demo it in photoshop, I have created a free photoshop action (macro) which can be used to automate the process, this can be downloaded here

In this video I describe how to fix oval stars. Ideally you don't want to take images with oval stars but sometimes it just happens and if the image is of a one time event like a supernova than you need to find a solution to improve your images. the video describes the process and then demos action in use.
