Stacking
Below is a typical image from a small AVI-sequence of 62 frames. Only after Aligning/optimizing the stacking page becomes available. The image on the left corresponds to the image in the sequence the slider is pointing at. The slider is accompanied by a red-vertical line in the graph. Set the slider at an image (the image quality should go down from left -> right) that you consider good enough for stacking (not completely blurred). Then you can use the vertical slider to set a limit to the difference between the image and the reference. When the difference is larger the registration is often not optimal. When you set the sliders the label on the lower-left will tell you how many images are still in the selection to stack. Stacking can be done with two (default on) options, “use image quality” and “partial coverage compensation”.
The image quality leads to weighted stacking, every image will be used in the stack with its own quality as a basis. The final stack is made up of image1*quality1 + image2*quality2 ..... imageX*qualityX. When this setting is off all the images get an equal weight. The partial coverage option is explained at this page and at this page .
After selecting quality/difference simple press STACK and the image will be stacked. After stacking you can save the stack both as a BMP or a FIT(s) file. You can now also proceed to the image processing section
