Hi Paul
I have always had a problem with this when using my DSI2 to the extent
that for a long imaging session I must manually align. The end product does not appear to suffer though. I spent a lot of effort in chasing flexure etc but with no improvement. I still get a little bit of movement when using my Canon 400D but not enough to prevent auto alignment. I use a QHY5 guide camera.
Cheers Peter
