I will be on HAL November cruise departing from Sydney for Solar Eclipse and have just upgraded my tripod and head for Giottos MTL8350B and MH59001. There is not going to be any vibration or movement to effect taking photos. During totality I hope that we will just drift. My biggest concern is crowded top deck. Rubber feet is what you should be using.This would insulate camera from any on the ship vibration.
