When inspected closely, your star trails suggest round stars for approx.
2 minutes, which I can achieve with my HEQ5. If you are lucky enough to have a mount with lower than average PE, you could maybe get a little longer, say 2.5 mins, but other external factors come into play which
prevent repeatability for any longer than that. You have a comparatively short focal length scope Rex. If you had say an 8" SCT, you would struggle to get 60 secs.
