Description

This 15 mm extension tube fits between the focuser, the existing 10 mm extension and the main tube on the F50G Guidescope. Referring to the picture below, simply un-thread the focuser with its attachment ring and thread this 15 mm extension to the existing extension. Then replace the focuser.

Different guide scopes have different back focus requirements. We machined this part to help optimize our guidescope for different cameras. Made in the USA on our cnc machines using 6061 T6 aluminum.

Natalie Y. ★★★★★

Finally got the spacing dialed in on my F50G setup—this 15mm tube made the difference for reaching focus with my camera. The threads mate perfectly with the existing 10mm extension, no wobble at all.

Emma ★★★★★

The threading on this 15mm extension is perfectly smooth, so it screwed right between the focuser and my existing 10mm tube without any wobble. My guide camera now sits at just the right distance to reach focus with room to spare.

Daniel ★★★★★

Finally got the back focus just right with this 15mm extension threaded between the focuser and the main tube. The threads are smooth and it mates perfectly with the existing 10mm piece. My guide camera now reaches focus without any extra spacers.
