Carson universal adapter great for iphone astrophotography - CARSON Universal Optics Adapter

I've really enjoyed using the Carson Universal Adapter with both an iPhone 5s and an iPhone 6 to mount to my telescopes. I find that it's an incredibly easy to use adapter, which is especially important when you're working in the dark. The mount doesn't provide a COMPLETELY 100% tight grip, but for certain applications (such as Astrophotography) it's more than enough! I wrote a more detailed write up (with pictures) of how I use it with my telescopes on my blog here: http://www.iastrophotography.com/a-new-favorite-smartphone-adapter-for-astrophotography/

Thanks!
