FITS Scrubber performs basic post-processing steps on a FITS file. The original use case was to preview a single (raw & unstretched) sub before setting off an imaging plan.

If you mean an offline or local version for say a Windows PC, the simple answer is no. This tool is web based and therefore platform agnostic.

• StarRemoval: Produces a star less image.
• Green tint removal: Removes the green tint from an image which is common in colour cameras.
• Colour palettes: RGB, SHO or HOO. This manipulates the colour channels for a particular colour theme.

FITS Scrubber does not clip any data and should be treated as just another tool in the bag. Take the quality TIF result into your favourite editor and perform additional editing to suit your requirements. I recommend not making your image "too black". It could be interpreted as concealing bad data or blemishes. Another thing to watch out for, is to ensure you only upload a linear (unstretched) FITS file. Otherwise, the result will effectively be a double stretch.
