With the deconvolution commands of Astroart it is possible to restore an image corrupted by blur or bad tracking. This can be also applied to film photos.

This image is a two minutes exposure of M13 with a TMAX 400 B&W film. After the Maximum Entropy deconvolution it is perfectly restored.

  Fast rotational gradient

The rotational gradient filter, also known ad Larson-Sekanina, can reveal faint details and jets inside comets.

Thanks to the speed of Astroart, this complex filter is performed in realtime on a 512x512 image, using an 2 Ghz PC.

  Gradient removal

This filter can correct almost any kind of uneven level of brightness in your images, usually caused by light pollution. Click to enlarge.

Remove gradient

In this example the satellite stray was removed with the cosmetic command "Remove lines".

  Adaptive filters

Astroart contains two unique adaptive filters. The Non-Linear high pass filter improves the sharpness of an image without black rings around stars or other artifacts.

The Adaptive Low pass reduces the noise of an image without blurring and loosing definition. Try them in the demo version.

  De-noise filter

This powerful filter attenuates the random noise of an image, without blurring the details.

Thanks to realtime preview, the best filter parameters can be found visually.


Astroart 6 includes a complete mask layer. Masks are used to analyze a part of the image, or to apply a filter only on that part.

Masks can be created using a Formula (for example: all pixels below a constant) or using the mouse, just like in graphic programs.
