Adjustable adapter for attaching a smartphone to a telescope. I used it with an iPhone 16. I am selling it because I was satisfied after taking a picture of the moon once. I had a hard time aligning the optical axis. Please be aware that it's not something you can just attach and immediately take pictures. I had to get creative to overcome the difference in height of the smartphone camera lens. It's probably quite easy with smartphones that don't have protruding lenses. Please research whether other smartphones are compatible. - Brand: Vixen - Model: Smartphone Camera Adapter - Included items: Instruction manual, mounting parts - Size adjustment: Slide mechanism with adjustable size - Purpose: Adapter for attaching a smartphone to a telescope
