Target Different position in LRGB

[OJ87]

Hi Everyone,

i upgraded my cam from DSLR to ASI 1600mm mono and i could make two imaging session the last two days. but unfortunately i accidentally moved my cam during the transport and i figured it out only today, the result is: my target Galaxy (M81) has diffrent positions in every imaging session, stacking every Channel resulted in diffrent angel for every channel. 

so any one could give me any trick of how i get them all in the same exact position so i can combine them in photoshop? and how to avoid such mistakes in future? i'm using APT for Imaging.

Thank you.
