Razor-sharp details at high magnification
The Sky-Watcher Planetary 2.5mm is made for moments when you want to get really close. Think of sharp craters on the Moon, thin cloud bands on Jupiter and tiny color differences on Mars. The short focal length gives you strong magnification, allowing you to see fine details that would otherwise disappear. You get a clear, calm image that lets you look longer without effort.

Clear image with high contrast
The eyepiece uses five multi-coated lens elements. More light gets through, less light is lost. As a result, your image remains clear even at high magnification. The 58° field of view gives you enough room to easily keep the object in focus. Low distortion keeps edges tight, so you can see exactly what's happening.
Comfortable viewing even in long sessions
The folding eye cup helps you see well without distractions. You fold it down or up, just the way you like it. The eye relief of 16 mm gives you enough room for relaxed viewing, even if you wear glasses. The rubber grip feels sturdy, so you can easily change the eyepiece without fumbling.
Practical and ready to use immediately
The filter thread makes it easy to use moon or color filters. Your image becomes quieter and details come out better. The compact size fits into any eyepiece set. Ideal if you want to take your planetary observations to the next level.
