FITS Scrubber: M31 Andromeda Galaxy

Drag the sliders to compare the scrubbed and raw images of the Andromeda Galaxy.

The "raw" state has had a Screen Transfer Function applied from PixInsight to stretch the image (otherwise it would appear almost black). The scrubbed image is the result of post-processing using the online tool: FITS Scrubber (click the link to view the actual scrubbed result and settings used).
