This image shows RegiStax after loading a set of images and selecting “multipoint” (method section).

The window on the right of the image is the multi-alignment control. On top we see that there are 2 methods for multi-alignment:
Simple: This will use one set of frames (based on the quality estimates belonging to the 1st alignmentpoint) for all alignmentpoints.
The advantage of this is that we are sure that the images will merge properly during stacking. The disadvantage is that we are not using the best possible set of frames for each alignmentpoint. Thats why we have choosen Multi-Quality to be the default method. This method will estimate for every alignmentpoint the best set of frames, so if you limit (after alignment) for instance at 100 frames this method will use the best 100 frames for every point. The total number of frames will therefore be larger than 100.

Next we have alignmentzones, when this is ON the program will show which areas are associated with the alignmentpoints. The alignmentpoints control all pixels that are the closest to their position.

Then the 2 buttons, estimate and clear alignpoints. Estimate tries to guess which features are interesting to use during alignment. So you do not have to specify the alignmentpoints yourself. This control works in conjunction with the minimum distance setting and makes sure that no alignmentpoint gets closer to a neighbour than the specified amount of pixels.

Finally Save/Load allow you to save/load sets of alignmentpoints. It not only saves the alignmentpoints and their sizes but also the frame you have used to set these points.
