Bluetooth SmartPhone Camera Shutter Remote Trigger

These smartphone will work with Android and iPhones. 

They're used to take a picture or start and stop a video recording on the phone without needing to touch the phone.

This is useful with astrophotography as touching the phone while it's attached to the scope to take a picture can jiggle the scope and ruin the picture or video.

With this remote, there is no movement of the scope when the picture or video is recorded.

Note: The remote comes with a CR2032 battery installed.
