Apparently the iPolar comes with an adapter in the box. I didn't know this and now I have 2. Technically 3 as the Skyguider Pro already has one bolted on the unit so I'm a bit confused why they would provide one in the box in the fist place. I haven't had a chance to use it so giving a 5 star rating because nothing is wrong with it from what I can tell. It just seems like a waste to include something that's not needed and bringing the unit price down would be advantageous top OPT from a sales standpoint.
It has been great this tracking mount has performed excellent no problems!
