AviStack is a freeware tool that registers, stacks and processes AVIs and image sequences.

Update of 14 January 2009.

Experimental wavelet sharpening and level adjustment!

Get your astronomy weather forecast from:

Version 1.74 now includes wavelet sharpening and level adjustment. These tools are fully usable but mostly meant to be a preview on what will be included in version 2.00 (which is currently in the making). Please, give us feedback via the AviStack Group!

The wavelet sharpening tool was developed by Joe Zawodny with some very kind support by Registax developer Cor Berrevoets!

You can find a description on how to use the wavelet sharpening tool by clicking on this link. You can either use the tool at the end of the processing chain or simply load a single image using the "Load images" option from AviStack's file menu.

Other improvements:

  • New AVI file picker (much faster than the old one).
  • No AVI file size limit. AS detects *all* frames within an AVI.
  • The "out of memory" bug when setting reference points has been resolved.
