IIRC the highest magnification I’ve ever used is 381x on Saturn through my 8 inch two nights in a row back to back . A couple rare nights indeed . That was with a 3x Barlow and my shortest 6.4mm Plossl . I probably could have gone higher but would have needed a 5x Barlow and tried some longer eyepieces . The focal length on that scope is only 812mm . I just didn’t have the oculars to go any higher and for as many times might see those conditions , I just couldn’t justify spending the money . Saturn was huge though at 381x . Colors on the disk and in the ring structure as well as disk shadows on the rings and ring shadows on the disk were stunning .
