Processing Page The power of RegiStax sits in the usage of Wavelets. This is a special filtering technique that is very good for enhancing details in images. Each wavelet layer carries part of the image within it. The lower numbered wavelets control the fine detail stored in the image whereas the larger numbered wavelets control the coarse detail. Each layer can be adjusted individually to reveal the desired amount of detail for your image. The processing page is where it all happens! 9. Before processing your image it is a good idea to save the aligned and stacked image as a Registax file before processing. This will allow you maintain your pre-processed image without having to go through the Stack and Align process over again. 9 10 10. On the right side of this screen are the six wavelet sliders that are numbered from 1 to 6. Start by moving slider #1 to a value of 50 and watch the image change when you release the slider. Move slider 1 back to its origin (or press Reset) and now move slider 2 to a value of 50, notice that this slider also changes the picture but in a much different way. As you will see the sliders with a larger numbers display more "averaged" images with less fine detail. Whereas the lower numbered sliders bring out more fine detail (and sometime unwanted "noise"). Now play with some of the layer-sliders to enhance your image to a desired effect. Press Reset to return to the normal settings. 8
