According to photos, the good design of the Celestron Nexyz camera holder does not interfere with the iPhone side buttons which are located mainly towards the top half of the cell phone. Therefore the phone mount will not cause trouble by depressing the side buttons when using the phone for astro imaging. The only concern for small telescopes may be the additional 10 oz. weight.
