Hi all,

For context:
Mount - EQ5
Guide Cam - QHY5-L-II
Image Camera - Modded 1100D

The issue I'm having is that my captured images alternate between 4290x2856 and 4272x2848 with each exposure. which is leading to problems with stacking. Until I started plate solving, I;d never noticed this issue before, and during an imaging session last night, I noticed it happening again so decided to do some tests.

Plate solving seems to be the trigger - if I run a set of images after platesolving, they alternate - if i restart after platesolving, all runs as expected.

What is happening here? It's not a critical fault, as I can get around it by restarting, but if I forget, I effectively lose half my data,

Thoughts??
