Looking for a small lightweight eq platform for an 8" F/5 portaball. Weight of scope is 30lbs. The platform must track for at least 45 minutes with less than 5 arcminutes error when aligned. It must have no visible vibration or jitter at high power (500x). I will adapt my portaball base to fit. Latitude is 37 degree north, so please only respond with platforms easily adjusted to this. I will be on vacation for a week starting tomorrow morning. Please respond with description and price, I will reply after 7/20/03. Thanks.
