  • SVBONY SV218 Universal Cell Phone Adapter Mount

    The SVBONY SV218 Universal Cell Phone Adapter Mount turns your smartphone into a powerful imaging tool for your favorite optics. Its adjustable clamp securely holds phones from 62mm to 105mm wide, while the eyepiece chassis connects to any barrel between 38.5mm and 49.3mm in diameter. Constructed from durable ABS, rubber, and metal, the entire adapter weighs only 77g, adding minimal weight to your telescope, spotting scope, or binoculars for stable afocal photography.

    Secure Grip for Phones 62mm to 105mm Wide

    The SV218 adapter features a robust clamping mechanism that accommodates nearly any modern smartphone, with or without a case. The adjustable grip expands from 62mm to 105mm, ensuring a firm hold on devices ranging from standard models to the largest phablets. This wide range means you can easily switch between different phones without needing a new adapter, making it a shareable tool for family members or club outreach events.

    Adapting to Optics from 38.5mm to 49.3mm

    This adapter's core function is its ability to rigidly couple your phone's camera to an optical eyepiece. The chassis is designed to clamp onto any eyepiece with an outer diameter from 38.5mm to 49.3mm, covering the vast majority of standard 1.25" and many 2" eyepieces found on astronomical telescopes, spotting scopes like the SVBONY SV28 and SV411, and binoculars. The secure connection is critical for preventing slippage and maintaining the precise alignment needed for sharp images of the Moon, planets, or distant wildlife.

    A 77g Build for Portability and Stability

    Weighing just 77g, the SV218 is engineered to be a lightweight addition to your field kit. Its low mass ensures it won't over-stress your focuser or upset the balance of your telescope or spotting scope, a crucial factor for maintaining tracking accuracy and stability. The combination of ABS plastic, protective rubber contact points, and a metal frame provides a durable structure that withstands regular use outdoors without adding unnecessary bulk.

  • Will the SVBONY SV218 adapter fit my large smartphone like an iPhone Pro Max?

    Yes. The SV218 adapter clamp supports phone widths from 62mm to 105mm. Since most large smartphones, including the iPhone Pro Max series, fall well within this range (typically around 78mm wide), the adapter will hold it securely, even with a standard case on.

    Can I use the SV218 with my SVBONY SV28 spotting scope?

    Absolutely. The SV218 is explicitly listed as compatible with the SV28 spotting scope. The adapter's eyepiece clamp range of 38.5mm to 49.3mm is designed to fit the eyepiece of the SV28, allowing you to easily capture photos and videos of wildlife or distant landscapes.

    How much does the SV218 adapter weigh and will it unbalance my telescope?

    The SV218 weighs only 77g (about 2.7 ounces). This extremely low weight is intentional to prevent balance issues, especially on smaller telescopes or mounts. It adds negligible strain to the focuser and won't require significant re-balancing of your optical tube.

    What materials is the SVBONY SV218 made of?

    The SV218 is constructed from a combination of materials for durability and function. It uses high-strength ABS plastic for the main body, soft rubber on the contact points to protect your phone and eyepiece from scratches, and metal components in the clamping mechanism for rigidity and longevity.

    Is it difficult to align my phone's camera with the eyepiece using the SV218?

    Aligning the camera can take a moment of practice. The key is to turn on your phone's camera app, look at the screen, and gently adjust the phone's position within the clamp until you see a full, circular field of view from the eyepiece. It's a manual process, but once aligned, the clamps hold it firmly in place.

    Can I use the SV218 adapter to take pictures of the Moon with my 8" Dobsonian telescope?

    Yes, this is an excellent application for the SV218. Most standard 1.25" eyepieces used with an 8" Dobsonian have an outer diameter that fits within the adapter's 38.5mm to 49.3mm range. By clamping your phone to a low-power eyepiece, you can easily capture detailed images of the entire lunar disk.
