SVBONY Plossl 25mm
Reliable, affordable, and well-coated: a solid first Plossl for any 1.25" telescope
Performance Scores
Overview
The SVBONY 25mm Plossl is a practical, no-frills eyepiece that earns its place in a beginner's kit. At 25mm focal length, it delivers moderate magnification, making it a natural starting point for scanning the Moon, splitting brighter binary stars, and getting your bearings on larger deep-sky objects like open clusters and nebulae. The 40-degree apparent field of view is on the narrower side compared to modern wide-angle designs, so do not expect sweeping vistas, but the view is clean and usable.
The fully multi-coated optics genuinely help here. At under $17, you might expect bare or single-coated glass, but the FMC treatment reduces light loss and improves contrast in ways you will notice, especially on faint targets. The blacked-out interior barrel cuts down on stray light scatter, which is a detail worth appreciating at this price point.
It accepts standard 1.25" filters via M28.5x0.6mm threads, so pairing it with a light pollution or moon filter is straightforward. The rubber grip ring and included plastic case are practical touches that protect a budget eyepiece you will likely reach for often. With over 1,000 Amazon reviews averaging 4.6 out of 5, it has a track record that backs up its value.

nice and clear. wider angle makes a clearer image
A million times better than the pack-in lens with my scope. Worth every penny
I'm just a rookie so my review must be taken according. I do like the wider angle of the 40mm eyepiece for certain viewing conditions. Materials seem like decent quality.
