Overview
The Celestron X-Cel LX 7mm is a short focal length eyepiece built with planetary and lunar observing in mind. At 7mm, it delivers high magnification on whatever telescope you pair it with, making it a practical choice when you want to push in close on Saturn's rings or the Moon's craters. The 60-degree apparent field of view is generous for this focal length, giving you enough sky to keep targets comfortable in the frame even at higher powers.
The six-element fully multi-coated optical design handles contrast reasonably well, and the blackened lens edges help cut down internal scatter, which matters when you are staring at a bright planet against a dark sky. Eye relief sits at 16mm across the entire X-Cel LX lineup, which is a genuine comfort advantage at this magnification range, particularly for eyeglass wearers. Being parfocal with the other X-Cel LX eyepieces is a practical benefit if you own more than one in the series, since swapping between them mid-session requires minimal refocusing.
The barrel accepts standard 1.25-inch filters, and the rubber grip and twist-up eyeguard are solid quality-of-life additions. At $93, it competes well against similarly priced options from Baader and Meade.

Really well made, crisp optics, great feel.
I guess you would consider the X-cel eye piece the 3rd tier offering from Celestron (2 up from the eye piece that comes with scope) and let me tell you what a diiference!! To start off with the build quality is vastly superior than that of the standard eye piece and there is a significant weight dif...
High quality EP all the way around. Great feel, etc. It might be too much power for the 8" reflector though. YMMV.
