![]() The output of AutoStakkert2 though is not a finished product and requires further post-processing to correct various image artefacts and pull out the inherent detail. ![]() A program such as AutoStakkert2 will then process the video, analysing the quality of each video frame, selecting the “best” frames, and then merging them to produce a single frame with less noise and more detail. Instead normal practice is to capture a high definition video at a high frame rate lasting for a minute or more, by attaching a webcam to a telescope in place of the eyepiece. ![]() ![]() The long awaited GIMP 2.10 release in April 2018, introduced 16-bit and 32-bit colour channel support, along with many other important improvements that enable high quality post-processing.Īstrophotographers seeking to present high detail images of The Moon, have long recognised that capturing a single still image is not sufficient. GIMP has been largely ignored by astrophotographers in the past since it only supported 8-bit colour channels. This post is going to illustrate a post-processing workflow for lunar surface images using the open source tools GIMP and G’MIC.
