Explore Scientific 9mm 100° 氬氣填充防水2吋目鏡 - EPWP1009-01

The 100° field of view is genuinely disorienting at first, in the best way—it feels like floating over the lunar surface. Took it out on a humid night and the argon purge kept the optics crystal clear with zero fogging. This one’s a keeper for deep-sky sessions.

I was blown away by how crisp Jupiter looked through this eyepiece — the argon purge really does keep internal fogging at bay during humid nights. The 100-degree apparent field makes sweeping for deep-sky objects feel almost immersive.

The field of view is so wide I can finally observe entire star clusters without nudging the telescope. Its argon purge gives me confidence taking it out on humid nights without worrying about internal fogging.
