The difference between a video capture made with a camera that shoots HD and a photograph taken with Nikon D80 DSLR is quite big.How I said in other articles, video camera I have, is much better than DSLR Why I came to this conclusion?
      With Nikon as photos made when shutter is open, so remains.On video, you can choose the frame for a snapshot, or you can process a large number of frames for processing in registax.
       In processing with registax, the photos taken with DSLR , must be made in such a way that craters must be all in the same position when you make pictures, because if you don't do so, in the alignment in registax , the square (the area chosen for alignment) is lost among other craters, running everywhere; alignment is impossible. Of course those who have a motorized telescope does not have such problems, the photos are made the same point, one after another.
      I do not know if you agree with mine.Anyway, starting last night I advanced in astrohotography problem with Nikon, but many gaps still remain,and questions.
     For those who have the passion astrophotography:
It is easier with a video camera or a DSLR?
With that camera you like the results?
Which kind of photos are more convenient for you to process in registax for example?
Registax photo processing with a DSLR is only possible if the pictures were done on a motorized telescope?
