It comes standard with T-2 (M42x0.75mm) threads for a 38mm clear aperture, but includes an S52 ring-dovetail adapter to expand that aperture to a full 42mm.

This component is essential for achieving the exact back focus required by field flatteners and reducers, utilizing an M68 dovetail receptor for a secure, non-flexing connection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003ePrecise M68 Spacing: Dial in 15mm to 20mm of Back Focus\u003c\/h3\u003e\n\u003cp\u003eAchieving perfect star correction across the field depends on hitting a precise back focus distance, often to within a fraction of a millimeter. The M68 VariLock allows you to dial in any spacing between 15mm and 20mm, providing the fine control that fixed-length spacers cannot. This eliminates the trial-and-error of stacking shims and ensures your optical corrector performs exactly as designed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSecure Rotational Framing with the M68 Dovetail\u003c\/h3\u003e\n\u003cp\u003eBeyond spacing, the M68 VariLock integrates a dovetail and receptor system for robust connections and rotational adjustment. Once your imaging train is threaded on, you can loosen the lock, rotate your camera to frame your target perfectly, and re-tighten without losing optical alignment or introducing tilt. This is a significant advantage over standard threaded extensions, which can loosen or bind when trying to adjust camera orientation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the primary use for the M68 VariLock 15-20mm Extension?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe M68 VariLock is designed for fine-tuning the back focus distance in an M68-threaded imaging train.

First, it creates a secure, zero-tilt mechanical lock that prevents flexure.

The M68 VariLock's continuous 15mm to 20mm adjustment range covers 17.5mm perfectly.

This will allow you to rotate your entire camera and filter wheel assembly smoothly. You can then orient your camera sensor to perfectly frame M31's elongated disc and then re-tighten the lock, all without affecting focus or optical alignment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the M68 VariLock introduce any flexure into my imaging train?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo. The M68 dovetail and receptor system is specifically engineered to provide a rigid, secure connection that resists flexure, even with heavy cameras or filter wheels.
