registax

Got a free version of Registax, but can't figure out how to use it. got
loads of mars/moon images and want to make better images,but the
tutorials don't work for me. Keep getting planet targets miss aligned.
I am not stupid, but the program is not user friendly. Can anyone help
me?

If your planet don't move too fast through the frame, you can select an
alignment box large enough to contain all the planet (for the moon, try
to choose a noticeable detail). Do not select the check box 'misalign
warning'.
If you are using the version 2, I've written this page that can help you

Version 3 is a bit more sophisticated, but the principles are the same.

Jake,

Registax is for stacking and aligning multiple images of the same object
taken in succession. What kind of camera are you using and what format
are the files in?

Are the images an AVI from a webcam or many shots from a digital still
camera?

Also how many images are you trying to process?

Most important how much object drift between images is there? Is the
image of Mars in close to the same area in each frame or are they all
over the image?

An optio pentax 4.3 meg pix... shoved straight onto the eyepiece of my
scope @ 25mill.

Most of the images (or all) are all within the same frame, but are, to
be honest, in different positions and spread about in the image capture
of the photos'.

However, I was lead to believe that this would not matter as the
Registax program would align them all and therefore give me a better
image.

Jake,

Registax can do it, but when they are theat spread out, you have to
manually align the frames by clicking on an easily recognizeable portion
of the subject.

For example say you are trying to align 10 shots of the moon, but not
all frames have the moon centered (due to scope drift etc...) this is
the process I'd follow:

1: Select all the frames/images you want to stack.
2: In the Align tab select manual aligning. scrool around the image till
the moon is more or less centered. You'll see a small box with a cross
hair in it. Put that over a crater on the moon and click.
3: Click the Align button and that will walk you through the rest of the
alignment.

Hope that helps

Craig

As another post answered in this thread, you probably can still get
Registax to align them but you will be prompted to manually select the
align target when Registax gets lost from frame-to-frame.

In the long run you will be best served to get a tracking mount if you
really want to get seriously into webcaming. Even a cheap Orion/Synta
mount is typically a big improvement -- but the higher magnification
you want to use the more important accurate tracking becomes to
maintain your sanity. ;-)

More information. I'm not an expert here but I believe Registax does a good
job of tracking your selected object (the thing you draw a box around) as
long as "Track object" is selected in the "Tracking options" drop down menu
of the "Aligning" tab. Also, give Registax a reasonable estimate of the
number of pixels your subject might move from one frame to the next by
choosing a high enough value in the "Alignment filter" option (make sure
it's checked, too) of the "Aligning" tab. My captures sometimes have the
subject travel from one corner of my screen to another due to poor polar
alignment but Registax follows my subject with no problem.
