I spent some time with both the Carson Hookupz 2.0 and Orion SteadyPix Quick Smartphone adapters on my Meade ETX90EC. I wanted to test them inside before trying outside because I had issues focusing and zooming in. The major issue I had the first time I tried was the iPhone case I use. Once I took it off, the smartphone adapters worked much better. I will try them outside next.
I created an article called Smartphone Adapters with more information comparing these two smartphone adapters for telescopes.
