Dynamic Alignment first attempt

[dhalliday]

I have two sets of images,of M33
Neither one is an award winner (love the Devil !!),but each has its stronger points.
It is all the same data,but one result has 12 more frames.
I tried DA on them,with pretty awful results!!
Mind you I was not sure what I was doing...
Once I have two "registered" files,do I use "add" in Math to blend them??
Here are the two frames;

It looks like you "merged" the incorrect images.

Lets take your two images (call them i1 and i2) , start the DyanamicAlignment process and select the two images.  There will be a Source (i1) and a Target (i2) image.  From the i1 image click on an isolated single star that you can easily identify in the i2 image.  DynamicAlignment will try to find the corresponding star, you will probably need to "help" it by moving the selection box in the i2 image.  Repeat this for 4 or 5 stars located at different places.  You want to make sure you have select stars towards all of the corners.

Once you are done, click on the green check mark in DynamicAlignment.  After a few seconds, you should have a new image.  It will be called i2_registered

Now that you have your two images you are ready to combine them.  Integrating images is not simply adding them together.  The easiest is that you average the two together.  So in PixMath you want to do avg(i1,i2_registered), select that you want to create a new image

So attached is the result that I got.

In addition, there is a really good tutorial video by Harry here ->http://www.harrysastroshed.com/pixinsighthomenewbie.html

Well...I am getting there...
In pixel math,is it
ave(x,y).....

That does not seem to work... sure about the brackets,comma?
Should I have TWO registered images...or just the one?
sorry to be a dolt...

It's avg, not ave

With the alignment process you will have your reference image and the output from the dynamicalignment.

So..

Start with two images, i1 and i2.

Run dynamicalignment, point to i1 and i2, do the alignment.  You will have one new image, i2_registered.

Combine i1 and i2_registered,

Crop the image because around the edges there will be areas that are from only one image.

If you have a bunch of images to align (registration) and combine (integration) you might want to look at the StarAlignment and Integration processes that can handle a batch of files.  Again same concept, you will have one image that will be the reference and all the others will be aligned to that reference image.

Thank again !!
