No resampling during alignment
Resampling X2 during alignment
Note the dirty marks caused
by dust on the CCD.
Here are the full-sized images which made up the collage on the previous page, in order of increasing magnification. All images were processed as near identically in Registax3 as I could manage. Except where indicated, all were done with resampling X2 (Mitchell option) during alignment. The major effect of enlarement seems to be loss of contrast.
