Use StarShrink to improve nebula images

Expert processing tips to enhance your astrophotos

Removing image noise, or unwanted artefacts, is one of the main aims of deep-sky astrophotography processing. The more we can reduce noise, the more freedom it allows us to process our images of nebulae and galaxies. This is particularly true for nebulae, where delicate gaseous details are easily overwhelmed or hidden. There are various noise reduction tools to help overcome the issue, but care needs to be taken applying them; use them too heavily and the target will look soft
