AviStack was primarily developed to process lunar images, but, it also works well with solar and planetary images. AviStack uses hundreds or even thousands of reference points to compensate for seeing-related distortions most effectively. This is decisive to detect even the smallest details in high resolution lunar images.
Despite the large number of reference points, AviStack is noticeably faster than Registax (when large numbers of reference points are used) and enables complete batch processing for all time consuming processing steps. Simply prepare within minutes all settings necessary to stack the film, save those settings and start the batch processing. That way you will later, e.g. on the next morning, find all the stacked final images on you computer.
You can already find in the Internet (and here under Bilder / Images) a number of examples where results obtained with AviStack are compared to those of Registax. A comment by Joe Zawodny: "I have not seen a case where RegiStax produced a better image, at best it was just as good, but often AVI Stack’s result was superior (especially when it came to the uniformity of quality)."
AviStack comes in two versions:
- A stand alone .exe file for 32bit Windows systems.
- An IDL save file.
run on all systems.
If you have already installed the stand alone version of AviStack and an update is available, you can simply download the IDL save file and replace the one already present in the AviStack program directory.
AviStack supports AVIs recorded with the Y800-codec (uncompressed grey scale), DIB-codec (uncompressed color) and I420/IYUV-codec (webcams). I.e. all grey scale and color films recorded with the cameras of The Imaging Source as well as films taken with the Philips ToUCams.
Additionally, it is possible to process series of images of the following formats: PNG, JPG, BMP, TIFF, JP2 (also 16 bit). That way basically every type of AVI can be used if it is split up into single frames beforehand.
I hope you find AviStack useful and enjoy using it!
