iOptron Smartphone Eyepiece Adapter

The adapter is designed to accommodate smartphones with a width between 58mm and 96mm and a maximum thickness of 14mm. Most modern smartphones, including larger models with cases, will fit within this range, but it is best to measure your device before purchasing.

The adapter is specifically designed to mount onto standard 1.25-inch eyepiece barrels. While it comes with a 12.5mm Plössl eyepiece, you can use it with other 1.25-inch eyepieces as long as they fit the mounting mechanism securely.

The adjustable clamp system allows for precise horizontal and vertical alignment. While it may take a few moments to center your camera lens perfectly over the eyepiece the first time, the durable aluminum construction ensures the alignment remains stable once set.

Yes, because the adapter uses a standard 1.25-inch barrel interface, it is compatible with many spotting scopes that accept 1.25-inch eyepieces. It is a versatile tool for capturing both terrestrial and celestial images.

The adapter is constructed from lightweight anodized aluminum, so it adds very little weight to your telescope. It is designed to be portable and balanced, making it suitable for smaller travel telescopes without causing stability issues.
