I also have the swarovski, if you live near a dolltree go buy a 1/4 cup measuring cup, it fits the swarovski eyepiece perfectly. I just carried my scope inside all the stores in town until I found what fit right.
Cut a hole the size of your smart phones lens in the center of the measuring cup.
Buy a cheap case for your smart phone via amazon(that's where I got mine) or some other place.
Line up the hole on your phone case with the hole in the measuring cup and glue together. I used a hot glue gun.
My buddy has the phone skope and my adapter works just as well. You can also buy the blue tooth hands free shutter release on amazon for $10, I haven't tried it yet but it looks pretty cool.
