مبدل تركيز ED APO بديل من Explore Scientific مقاس 2 بوصة - FOCEDAPO-00

Installed this on my ED APO this weekend and the dual-speed focuser makes fine adjustments in planetary viewing so much easier. The action is smooth and holds position without any drift, even with a heavy camera attached.

The dual-speed knob makes fine-tuning at high magnification feel buttery smooth, and the whole unit is noticeably more solid than what came on my scope. Took about twenty minutes to install and I've had zero focus drift since.

Swapped out the stock focuser on my 80mm triplet, and this one feels much more solid with zero play. The fine-focus knob lets me dial in Jupiter's bands with no backlash at all.
