Hi All,
Last night i took 5 30sec exposures of the milkyway with the camera and now i would like to align and stack them in photoshop CS6. I have the book "photoshop astronomy" and there is a good tutorial in there which covered this with deep sky work but not widefield.
The problem i ran into was aligning the images. this is ok when the FOV is quite narrow, but when i tried to align the images they would not match up as i had to rotate them also around the SCP which proved difficult. I can move them up and down and rotate the images, but they would not align. I was using the "differences" method in PS.
Whats the way others are aligning their widefied images.
I could also use CCDStack 2 if thats better.
thanks
Josh
