Sirius M54 Microfocuser

Upgrade your 50mm guidescope with this precision micro focuser, offering 10mm of smooth, fine-tuned travel for razor-sharp star focus during autoguiding sessions. Compatible with popular finderscopes from Skywatcher, Celestron, GSO, and more, it features both M42 and 1.25-inch connections to suit a wide range of guide cameras and eyepieces. A brass compression ring ensures a secure, scratch-free hold for reliable performance all night long. Use with right-angled finderscopes.

The Sirius 2" Parfocal Ring eliminates the need to refocus your telescope every time you swap eyepieces. Simply lock the ring onto each eyepiece barrel at its precise focus point, and enjoy seamless, shake-free transitions between magnifications during your observing sessions. It's also ideal for astrophotography, allowing you to match your calibrating eyepiece's focus to your camera for fast, accurate results.
