If you had the same answer then ... The all time told taboo limit of 60-90s for AVIs of Jupiter is dead !! It had sense only in my opinion when registering with the external disk of the planet ! If one register on a smaller area in the central part of the disk then capture time can be extended a lot. On the GRS at the meridian eg. I guess half an hour (15min before, same after) could be workable to get a stunning GRS resolution if good seeing !
