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.
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.
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.
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".
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.
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.
