I cheated somewhat. I had some good binoculars with me that day and I was juggling those in one hand while holding the iPhone to the eyepiece :)

(and I checked, it was iPhone 4 not 5)

I was wondering how the zoom was so clear. However, I'm familiar with the struggle of shooting that way. I don't have a phone mount for my telescope, but with enough struggle, I can get a decent pic from the viewfinder on my phone. So don't play it off as cheating. It was a bit of skill to get both the binocs and the phone steady and aligned enough to get it.

Either way, it's a shot not everyone is going to have posted to their socials.
