Hi guys. I can get away doing up to 2 minutes exposures with my Rasa 8 and Skywatcher EQ6 R Pro mount and my stars are fine. Do I still need to guide,even if I'm doing 10 seconds exposures?
Guiding
If your polar alignment is sufficient, and the results are acceptable to you, there is no reason to guide.
I very often image unguided 120s.

Thank you 😊. I was just thinking about walking noise. If that might be an issue if I don't guide
You can set your sequence to re-center every 5-10 frames or so. This will act as a way of dithering. Just set your center tolerance a litter higher than you do when guiding.
Okay thank you
