Explore Scientific 2" AR Series Focuser


Enhanced Dual-Speed 2" AR Series Focuser by Explore Scientific

Optimize Your Viewing Experience: Unveiling the premium Explore Scientific 2" AR Series Focuser, engineered for astronomy enthusiasts seeking precision and versatility. This dual-speed focuser, featuring an inclusive 1.25" compression ring eyepiece adapter, offers seamless compatibility with both 2" and 1.25" eyepieces and accessories. Securely lock in your eyepieces or barreled accessories with ease, thanks to the adapter's robust design and three set screws.

Precision Micro-Focusing: Elevate your celestial observations with the focuser's precise 10:1 micro-focusing capability. Achieve sharp, detailed views with tenfold less effort—rotate the micro-focusing knob just ten times to match the focus adjustment of one full rotation of the rough focus knob. Designed for user comfort, the large, knurled focus knobs ensure effortless operation, even in cold conditions or while wearing gloves.

Adaptive Tension Adjustment: Tailor your focusing experience with the focuser's adjustable tension feature. This functionality allows you to lock the drawtube or modify its tension, accommodating changes in the weight of eyepieces, cameras, and other astronomical accessories. It's an essential feature for both amateur stargazers and seasoned astronomers, ensuring stable and precise focus under varying equipment loads.
