أنبوب تمديد إكسبلور ساينتفك 2 بوصة لموجد التركيز - ESRPEXT2

Finally got the spacing right for my eyepiece to reach focus—that extra 2" made all the difference. The build quality is solid and it threads on smoothly without any wobble.

This extension tube fit perfectly on my focuser threads and gave me just the in-focus I needed for my new camera setup. The 2" length feels solid and machined, with no wobble or play at all.

I needed a bit more clearance between my eyepiece and the focuser, and this tube clicks in solidly with no wobble. The machining on the inner edge is smooth, and it doesn't introduce any extra play in the drawtube travel.
