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

1 - Align 2 - Stack 3 - Wavelet

Frames of your video Your video is divided into many individual frames Most planetary imaging requires several hundred, perhaps around 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 – 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!
