Meade Series 5000 Eyepiece

This eyepiece requires a 2-inch focuser. Please check your telescope's specifications to ensure it accepts 2-inch accessories, as it will not fit standard 1.25-inch focusers.

A parfocal design means that when you switch from this eyepiece to another parfocal eyepiece in the same series, you will need little to no refocusing. It saves time and keeps your target centered while you change magnification levels.

Yes, 22mm is considered very generous eye relief. It provides enough distance between your eye and the lens to comfortably view the entire 70-degree field of view while wearing eyeglasses.

Yes, the barrel is threaded for standard M48 x 0.75 filters. This allows you to easily attach light pollution or color filters to enhance your planetary or deep-sky observations.

The waterproof seal prevents internal fogging and protects the optics from dew and humidity during long, late-night observing sessions. It essentially ensures the internal glass elements remain clean and clear regardless of environmental conditions.

At 23 ounces, this is a substantial eyepiece. If you are using a smaller or manual telescope, you may need to adjust your counterweights or tension knobs to prevent the scope from drifting or tipping due to the added weight.
