Clear details at high magnification<\/h3>\n\n\n\n

The Sky-Watcher 4 mm Planetary gives you high magnification without collapsing your image. You can see sharp edges on the Moon, tiny structures in Jupiter's cloud bands and fine color differences on Mars. Everything feels closer, making it easier to discover new details. The image remains calm, so you can look longer without getting tired.<\/p>\n\n\n\n

Bright and high-contrast image<\/h3>\n\n\n\n

The eyepiece uses five multi-coated lens elements. As a result, little light is lost. Your image remains clear, allowing you to see more on planets and other small objects. The 58\u00b0 field of view gives you enough room to follow the object smoothly. Low distortion keeps lines tight, so you see exactly what's happening.<\/p>\n\n\n\n

Comfortable and easy to use<\/h3>\n\n\n\n

The folding eye cup helps you look relaxed. You fold it down or up, whatever feels comfortable. The 16 mm eye relief gives you plenty of room, even if you wear glasses. The rubber grip makes changing easy, even in the dark or with cold hands.<\/p>\n\n\n\n

Practical for every session<\/h3>\n\n\n\n

The filter thread makes it easy to use a moon or color filter. This way you get even more detail out of your observation. The compact design fits easily into any eyepiece set. An ideal upgrade when you want to view planets with more sharpness and peace of mind.<\/p>\n\n\n\n
