So I'm just starting to image and trying to learn as much as I can before I take the next steps. Relative, to stacking images, does this mean every picture you use DSI or Registax to stack must be exactly the same in terms of size, where stars are located within the frame?
In essence, if the stars have shifted a little in one frame to another, does the software adjust to put the stars over the stars so they are aligned properly?
Hope this makes sense. And yes, I'm starting to read all the good books I see folks recommending. Thank you so much.
There are two processes, aligning the stars by shifting the subexposures positions, and stacking the data. With some software, operated in certain ways, those are handled by the software in one operation setup by you. Other software, when you use other methods, may have you performing two operations.
You'll find some people recommending PixInsight, a complicated program. One of its strengths is that it can align and stack most anything, even subexposures from different cameras that are different sizes and twisted with regard to each other.
But it's a difficult program to learn, there are easier, that can handle a large majority of the situations you'll encounter.
