For imagers using the E-130, E-160, or E-180, hitting the exact back focus distance is not optional—it's the only way to achieve sharp stars across the entire field, and this 1.2mm spacer is often the missing piece.\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\u003ePrecision 1.2mm Spacing for M54 Imaging Trains\u003c\/h3\u003e\n      \u003cp\u003eFast, flat-field astrographs demand mechanical precision that matches their optical design. A deviation of even a single millimeter in back focus can introduce significant star distortion at the edge of the frame. This adapter adds exactly 1.2mm of path length to your M54 imaging train, a common requirement when integrating accessories like filter wheels or off-axis guiders that don't quite match the telescope's native spacing.\u003c\/p\u003e\n      \u003cp\u003eConstructed from black-anodized aluminum to minimize internal reflections, this adapter joins two components with female M54 threads, creating a rigid connection with minimal added length.
