مخفّض F/3 0.6X لتلسكوبات FSQ-106ED-XIII/X4 وFSQ-130ED (TKA38581)

The illuminated crosshairs on this reducer make centering it on the FSQ-130ED’s sensor so much easier, and the threaded locking ring feels reassuringly solid. Star shapes stayed pinpoint across my full-frame chip after dialing in the back focus.

Finally got this reducer dialed in on my FSQ-106—the f/3 speed is a game changer for capturing faint nebula detail in a single night. The threaded connection to the telescope adapter fit perfectly with no wobble, and star shapes stayed crisp across the whole frame.

I was worried about the back focus, but the thread-on design made installation straightforward on my FSQ-106EDX4. The first test images showed a perfectly flat field with no noticeable vignetting.
