Hi all,

My first post on here.

I've recently moved over to Stellarmate on a Raspberry pi after does pretty decent success with Astroberry and a PC. Unfortunately, when trying to take a sub (180s exposure) my image has jumped/glitches creating a mirror image overlay to the right of my frame image. Image was taken with a Samyang 135mm & Canon 600d on a HEQ5 pro mount. Can't see it being tracking as I've got pretty solid stars, just double the amount I should have!

Any ideas how to overcome this or what's causing it please?

Clear skies,
Sam
