أنبوب تمديد بطول 33 مم و69 مم (SFE-M69-033)

Threaded perfectly into my camera setup without any wobble, and the 33mm length gave me the exact backfocus I needed for my planetary shots. Night-and-day difference in star sharpness compared to the short spacer I was using before.

Finally got the spacing I needed for my imaging train to reach focus with the new camera. The 4mm male thread seated firmly without any play, and the 20mm female depth means my nosepiece grips securely. Build feels solid for the price.

I was worried the female thread depth might be too shallow, but it holds my camera securely. Works as expected for macro shots.
