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.
 

De-noise filters


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

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

Trichromy


Several white balance methods, and the realtime preview, let you easily combine three channels.
trichromy
This image of the Fishhead Nebula (IC 1795) was made with the "Hubble palette", using the S-II, H-Alpha and OIII filter. Image and processing by Rudi Bjørn Rasmussen.
 

Preprocessing


Thanks to the instant star recognition and SIMD code Astroart can stack hundreds of images very quickly.
Preprocessing
In a few seconds all images are normalized, corrected, rejected if needed, aligned and summed into a high quality result. Try it with the demo version.
 

Mosaics


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

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.
 

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".
 

Masking


Astroart includes a complete mask layer. Masks are used to process or analyze a part of the image.
Masks

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

Auto-alignment


To increase the signal to noise ratio it is necessary to acquire many images and then sum them.
Align
Astroart aligns and stacks hundreds of images very quickly, using optimized algorithms for star fields, comets, planets and spectrums.
 

Common pictures


Powerful filters like Deconvolution and FFT can be applied to your own photos.
Common images
Working with 96 bits (32 for every R,G,B channel) allows to correct better the defects and to balance accurately the colours.
