Rose is a premium electronic focuser engineered for extreme precision — achieving up to 0.1 micron per step. It delivers the kind of performance typically reserved for focusers several times the cost.

I would be giving William 5+ if I could. I purchased an item from him and he said he would refund the item if i was dissatisfied for any reason. I returned the item to him as it did not work for me and a refund was given
