The Basics of Registax 6 David O’Dell Anderson High School Austin, TX 3 Main Features • Preferably done in this order: 1. Alignment – does what you think it does 2. Stack – vertically stacks all the images you align into a one single image 3. Wavelets – image sharpening, color enhancement, denoise 3 - Wavelet 2 - Stack 1 - Align Frames of your video • Your video is divided into many individual frames • Most planetary imaging requires several hundred, perhaps around 200-400 • More frames don’t always mean a better image Click Select, Find a video file Reference image • A reference frame is what you decide to be the best looking image in your video • Using the frame slider at the bottom, choose a frame you feel is one of the best images Frame Slider First step: Alignment • Alignment must be done because your video file always shows some wobble or interference due to: – Wind blowing against the telescope – Birds or airplanes flying over head – Accidental touching or bumping the telescope • Clicking the left mouse button on the image displays a little red dot, this is an alignment point Alignment points • Alignment points are used to align all the images based on your chosen reference image • Registax can do this automatically, or you can do it manually, depending on how large the planet appears in your video • Small planet images may require you to set your own alignment points Goal of alignment points • You want: – Several but not an insane amount of them – To stay away from the edges of very bright and very dark areas – Be inside the planet / object, not around it – Large planets, around 20-30 – Small planets you might only have 5-10 Set Alignment points, then click ALIGN Limit the number of frames • You will never use ALL of your frames, you don’t want to • You only want the best of the best frames • You must limit the amount in the limit setting Select the BEST FRAMES %, Use around 70 – 90%, then click LIMIT Stacking process • Probably the easiest once you have everything else done • The default values are fine • Just click STACK! Leave values as they are, Click STACK Save your raw data after you stack On to the Wavelets for sharpening • Experiment with the various sliders one at a time, starting with Layer 1 • You can adjust brightness / contrast and lots of different color adjustments in this section Adjust the various sliders to increase sharpness After adjusting • Once you finish adjustments click DO ALL • If you don’t like what you see, readjust and click DO ALL again • If you want to restack, click the STACK tab and repeat the process • After everything, click SAVE IMAGE and show it off!
