TMB PlanetView Planetary Eyepieces:
The TMB PlanetView Planetary Eyepiece series is designed for high-magnification planetary and lunar observing, delivering sharp, high-contrast views with excellent eye comfort. Choosing the right focal length for your telescope typically provides a significant upgrade in magnification and fine detail compared to the stock eyepieces supplied with most telescopes, making planetary features clearer and easier to observe. Featuring a 5-element optical design and a wide 58° apparent field of view, these eyepieces offer a more immersive experience than traditional narrow-field planetary designs while maintaining the crisp detail needed for serious observing.
Fully multi-coated optics and internal baffling maximise light transmission and suppress stray reflections, improving contrast on subtle planetary features and fine lunar detail. The large eye lens and generous eye relief make these eyepieces comfortable to use, especially during long observing sessions or when wearing glasses.
Built with an all-metal housing and a fold-down rubber eyecup, TMB PlanetView eyepieces are robust, practical, and compatible with all standard 1.25" focusers and filters. They are also Bintel’s number one recommended first upgrade for most telescopes, offering one of the simplest and most noticeable improvements you can make to planetary and lunar performance.
The 7mm TMB PlanetView:
The TMB PlanetView 7mm Planetary Eyepiece is an excellent match for Schmidt-Cassegrains and large Dobsonians, providing comfortable high magnification for planets and lunar observing. It works particularly well with telescopes such as the Celestron StarSense Explorer DX6" SCT, Celestron NexStar 4SE, and Celestron StarSense Explorer 12" Dobsonian.
