أنبوب تمديد طويل 55 مم من Stellarvue 88.5 مم (STE-M88.5-05)

Machined so precisely that it screws on without the slightest wobble—turned my imaging train into a rock-solid assembly. The 55mm of extra reach was exactly what I needed to hit focus with my reducer, and the threads are buttery smooth.

The threads mate perfectly with my 2.5" focuser, and the extra 55mm gave my camera just enough back focus to nail the stars across the entire frame. Machining is buttery smooth with zero play when tightened down. Worth every penny for anyone fighting spacing issues.

I was worried about adding length to my imaging train, but this tube threaded on perfectly with no wobble. The 55 mm extension gave me just the right back focus for my astro camera.
