ترقية التركيز الدقيق MEF3 لمقابس 2.7" و 2.6" و 2"، و E-130D و E-180 Astrograph (TKA00733)

The knob turns so smoothly that I can lock in focus without bumping the tube—it completely changed my imaging sessions. Took about ten minutes to swap onto my 2" focuser, and the fine control is a night-and-day difference.

The fine adjustment is incredibly precise—just a tiny turn of the knob moves the focus by a hair. I was able to dial in perfect focus on my E-130D much faster than with the stock focuser. Definitely worth the upgrade for anyone doing astrophotography.

I was nervous about the install, but the fit on my E-130D was perfect and the fine adjustment knob gives me precise control that was missing before. Focusing on faint galaxies is noticeably smoother now.
