Even the way StarTools displays and scales images, has been created specifically for astrophotography.
StarTools implements a custom scaling algorithm in its user interface, which makes sure that perceived noise levels stay constant, no matter the zoom level. This way, nasty noise surprises when viewing the image at 100% are avoided.
StarTools implements a custom scaling algorithm in its user interface, which makes sure that perceived noise levels stay constant, no matter the zoom level.
Even more clever, StarTools scaling algorithm can highlight latent and faint patterns (often indicating stacking problems or acquisition errors) by intentionally causing an aliasing pattern at different zoom levels in the presence of such patterns.
I'm relatively new to image processing and just wanted to say how straight forward and powerful StarTools is.
At this point, things to look out for are; Stacking artefacts close to the borders of the image.
Noise reduction and grain shaping is performed in three stages.
The module can also be used as swiss pocket knife for gamma correction, normalisation and channel luminance contribution remixing.
You can convert everything you see to a format you find convenient. Give it a try!
