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.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eSecure Grip for Phones 62mm to 105mm Wide\u003c\/h3\u003e\n      \u003cp\u003eThe 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.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n    \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eAdapting to Optics from 38.5mm to 49.3mm\u003c\/h3\u003e\n      \u003cp\u003eThis 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.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eA 77g Build for Portability and Stability\u003c\/h3\u003e\n      \u003cp\u003eWeighing 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.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWill the SVBONY SV218 adapter fit my large smartphone like an iPhone Pro Max?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eYes.

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.\u003c\/p\u003e\n  \u003c\/div\u003e\n        \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the SV218 adapter to take pictures of the Moon with my 8\" Dobsonian telescope?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eYes, this is an excellent application for the SV218.
