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.
Deconvolution
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.
Preprocessing
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.
Trichromy
Several white balance methods, and the realtime preview, let you easily combine three channels.
This image of the Fishhead Nebula (IC 1795) was made with the "Hubble palette", using the S-II, H-Alpha and OIII filter.

Mosaics
Mosaics can be acquired automatically using built-in scripts.
When processing, using the live preview, 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 it 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.
The satellite stray was removed with the cosmetic filter "Remove lines".
Auto-alignment
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 LRGB and LCMY quadrichromy, 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's 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's possible to correct better
the defects and to balance accurately the colours.
