ملحق توجيه F50G 10 مم (STE-M52-010)

Finally got the guide scope to reach focus with the reticle eyepiece — that 10 mm spacing was exactly what was missing. The threads are clean and it screws on without any play.

Exactly what I needed to get the reticle eyepiece to reach focus with my guidescope. The threads engaged smoothly and it feels solidly machined.

Snapped this 10mm extension between the focuser and main tube so I could finally use my reticle eyepiece for alignment, and the threading matched up perfectly with no wobble. It's a tiny part but it turned my guidescope into something way more useful on clear nights.
