Let’s Dive into Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece
The Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece promises to redefine your astronomical viewing experience. Offering a massive 100-degree apparent field of view and housed in an argon-purged, waterproof body, this eyepiece aims to deliver stunning, immersive observations in any environment. I was excited to get my hands on this piece of equipment, particularly given the Explore Scientific reputation for quality optics.
I’ve been chasing the perfect wide-field view for years, battling narrow fields of view that felt like looking through a straw. I wanted an eyepiece that could pull me into the cosmos, not just show me a tiny sliver of it.
Upon unboxing, the immediate impression is one of substantial quality. The eyepiece feels solid, with a reassuring weight (29.4oz) that speaks to the quality of the glass and construction. It’s a sizeable piece of equipment, but the smooth finish and clean lines suggest a well-engineered tool.
Compared to my existing 20mm Plossl and a 10mm wide-angle eyepiece, the Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece stood out with its significantly wider field of view promise. I had also considered a competitor’s 13mm eyepiece, but the Explore Scientific’s waterproof and argon-purged features swayed my decision, offering better protection against the elements during my often-damp observing sessions. My aging eyes and increasing light pollution were also factors in my decision to get the wider field.
My first impression was a mix of excitement and cautious optimism. The promise of a 100-degree field of view is tantalizing, but I knew that delivering that level of immersion without distortion is a significant challenge. Would it live up to the hype, or would it be another expensive disappointment?
Real-World Testing: Putting Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece to the Test
First Use Experience
My first test was conducted at a remote dark-sky site I frequent about two hours from the nearest city. I mounted the Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece on my 8-inch Schmidt-Cassegrain telescope on a night with average seeing conditions. The goal was to observe the Orion Nebula (M42) and some open star clusters.
The performance was immediately striking. The 100-degree field of view was incredibly immersive, drawing me into the heart of the Orion Nebula like never before. Even though the skies weren’t pristine, the argon purging seemed to help maintain good contrast, and I felt I was seeing deeper into the object.
Using the eyepiece required a small adjustment in viewing technique. With such a wide field, keeping my eye properly positioned relative to the eye lens was crucial to avoid kidney-beaning and off-axis aberrations. Once dialed in, it was smooth sailing.
After first use, I was very impressed but also noticed a slight amount of edge distortion. It wasn’t significant enough to ruin the experience, but it was there. This confirmed that I needed to be conscious of proper eye placement to get the most from the eyepiece.
Extended Use & Reliability
After several months of consistent use, the Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece has become a staple in my observing kit. It has consistently delivered excellent views of a wide variety of celestial objects. The eyepiece has accompanied me on several trips, and the waterproof feature has provided peace of mind during dewy nights.
So far, the eyepiece shows no signs of wear and tear, despite being transported in my kit regularly. The body’s finish seems resistant to scratches, and the optics remain pristine after cleaning.
Cleaning is relatively straightforward with a microfiber cloth and lens cleaning solution. I’ve been careful to avoid over-cleaning to prevent any potential damage to the lens coatings.
In comparison to my previous eyepieces, the Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece is in a different league. The wider field of view and better contrast provide a more immersive and detailed observing experience. The eyepiece has certainly exceeded my expectations.
Breaking Down the Features of Explore Scientific 14mm 100 Degree Series Argon-Purged Waterproof Eyepiece
Specifications
- Focal Length: 14mm. This determines the magnification when used with a specific telescope.

- Eye Relief: 14.5mm. This is the distance your eye needs to be from the lens to see the full field of view.
- Barrel Size: 2.00″. The larger barrel size allows for greater light transmission and is sturdier than the 1.25″ size.
- Weight: 29.4 oz (836g). This gives the piece substantial heft.
- Length: 157mm
- Width: 70mm
- Field Stop Diameter: 24.4mm. Determines the true field of view in conjunction with the telescope’s focal length.
- Argon-Purged: Prevents internal fogging and protects internal components from moisture and contaminants.
- Waterproof: Allows for use in damp environments and easier cleaning.
These specifications matter because they directly impact the viewing experience. The 14mm focal length provides a useful magnification range for many telescopes, while the 100-degree field of view delivers an immersive, panoramic view. The argon purging and waterproofing add to the eyepiece’s durability and longevity.
