That is so nice that they share their astrophotography equipments!
I generally activate long exposure noise reduction, it doubles the time of exposure because of the dark frame, but it works well. I think it is acceptable for 30-60 seconds exposures, but it becomes a burden for longer durations. Are they suggesting doing the dark frame manually once for each exposure time?
In my small astrophoto experience I’ve learned to disable camera image stabilization when using a tripod as it leads to weird movement patterns (with my Fuji X-T4), I don’t know how it works with other manufacturers.
