Hi all,

I have noticed that when I leave the scope taking a series of images while being guided, that it slowly drifts one direction over time. The result is that longer exposures are not possible (more than 60-90 seconds). The QHY5 keeps on guiding and the graphs shows all the usual small oscillations, but the overall image still drifts over time.

Is there any way to fix this, or is it normal? I know I am imaging at a long focal length (2350mm), so that longer exposures are more difficult. I would love to be able to image 5 to 10 minutes rather than one...
