I received this mount a week ago and have used it for the first time. Accurate, beefy, precise, easy to set up and use, wireless; the list goes on. Explorestars is a great app and very user friendly combined with astro software for viewing and capturing the night sky. Deep sky targets, galaxies, nebulas, star clusters?...this mount tracks them all very precisely. My scope, a Williams Optics zenithstar 73 doublet APO. The weights that came with it handle a much heavier setup, so I had to get the Explore Scientific 5 lb one to balance my light refractor. Just wow. You will not go wrong, it is so easy to use.
