Danubia 2xバーローレンズ 1"天体望遠鏡アイピース用

I was able to use this with my smaller 1" eyepieces and it made the craters on the moon much clearer. The lens threads on smoothly and doesn’t seem to soften the image at all.

The magnification jump is exactly what I needed for crisp lunar craters—sliding it between the eyepiece and diagonal takes seconds and feels solid. Jupiter's bands popped out way clearer than at native power, and the threads on the barrel are smooth without any wobble.

I can finally split tight double stars like Albireo with my 25mm eyepiece and this barlow. The extra magnification makes lunar craters pop in a way I couldn't get before. Best $30 I've spent on an upgrade.
