After some advise. just took 30 images in a row to do a star trial image. Everything locked down and using an automated remote timer so i am not touching anything. Sequence was 5min exposure with 1 second gap.

But here's the problem. Every second image, the entire image has shifted by the same amount. For example 15 even number files are perfectly aligned with each other,and all 15 odd numbers align with each other but the even and odds have shifted by the exact same amount.

Any thoughts as to what the hell is going on
