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
• Most planetary imaging requires several
hundred, perhaps around 200-400
• More frames don’t always mean a better
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
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,
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!
