Adaptive filters

Astroart contains several adaptive filters. The Non-Linear high pass filter improves the sharpness of an image without introducing artifacts.

The Adaptive Low pass reduces the noise of an image without blurring and loosing definition.


With the deconvolution filters it's possible to restore an image corrupted by blur or bad tracking. This can be also applied to old film photos.

This image of M13 were taken a TMAX 400 B&W film. It was restored via Maximum Entropy deconvolution.


The following example shows the Preprocessing Window with its file boxes filled by simple Drag & drop.
In a few seconds all the images are corrected for dark frame, flat field, aligned and summed into a single image.

Colour cameras

Colour cameras and DSLRs needs to reconstruct the colour information from the RAW image.
Several white balance algorithms, with very fast full-frame preview, let you easily obtain the best result.


Mosaics can be acquired automatically using built-in scripts.
When processing, using the full-frame preview (in realtime) it's very easy to tune the brightness of every frame and to fade the overapped region.

De-noise filters

These filters attenuate the random noise of an image, without blurring the details.

Thanks to realtime preview, the best filter parameters can be found visually. Just try with demo version.

Gradient removal

Six filters to correct any kind of uneveness of illumination in your images, usually caused by light pollution. Click to enlarge.
Remove gradient
The satellite stray was removed with the cosmetic filter "Remove lines".


To increase the signal to noise ratio it is necessary to acquire many images and then sum them.
Astroart is able to align and stack hundreds of images quickly, using different algorithms for star fields, spectrums, comets, planets and wide objects.

LRGB quadrichromy

Astroart fully supports RGB and CMY tri-colour imaging as well as LRGB and LCMY, with standard L*A*B colour conversion.
This example shows the benefits of using a fourth frame (luminance). Noise in the colour frames don't affect the sharpness of the final image.

Common pictures

With Astroart it is possible to apply the most powerful filters like Deconvolution and FFT to your own photos.

Working with 96 bits (32 for every R,G,B channel) it is possible to correct better the defects and to balance accurately the colours.
