PHYS397R-Astrophotography (1 credit - Spring 2015) Processing Planetary Movies using Registax This page explains how to take raw .avi movie files of planets or the Moon and process them to produce much sharper and clearer images. As an example, Figure 1 shows the power that the program Registax has in significantly improving the quality of planetary image. Fig. 1: Example of the difference between Jupiter's appearance in the raw .avi movie file (left) and Jupiter after processing the movie file through Registax (right). The general procedure to process .avi movie files like the Jupiter one above is the following:
You should now have one blurry image now on the screen, but don't worry, you'll make it better! In this next part, which may take some time, you are going to sharpen the single image that appears on the screen.
Fig. 2: To sharpen the image: Start by setting all of the values in the red box to the values listed above. Fig. 3: To make the image brighter: a. Click on the Direct Box and b. Move the right side slider bar until it is just to the right side of the "mountain". If you are happy with the image on the screen, click Save Image on the upper left corner. If you want it to be better, play around by adjusting things in the red box in Fig. 2. Specifically, move the yellow slider in Layer 1 to the left to make image smoother, and to the right to make it sharper, just play around until you get what you think looks best.... |
