The Sky-Watcher Skymax-90 is a compact Maksutov that you can take anywhere. You get clear, high-contrast images with no fuss. Perfect if you are taking your first steps into astronomy, but also ideal for nature viewers who want to see sharp details. Because of its small size, it fits in almost any bag, so you always have it with you.<\/p>\n\n\n\n

\n
\"Skywatcher<\/figure>\n<\/figure>\n\n\n\n

Powerful and compact<\/h3>\n\n\n\n

The 90 mm aperture gives you enough light to see the Moon, planets and bright nebulae clearly. You immediately notice how calm the image remains, even at higher magnifications. The long focal length of 1250 mm helps with this: you easily get large magnifications without softening your image.<\/p>\n\n\n\n

\n
\"Skywatcher<\/figure>\n<\/figure>\n\n\n\n

Clear image, day and night<\/h3>\n\n\n\n

Thanks to the Maksutov design, your image remains sharp and high in contrast. That's nice when you want to see lunar cracks, Saturn's rings or Jupiter's bands, for example. During the day, use the same telescope for birds and wildlife. With the right adapter, you can even take pictures, without expensive camera accessories.<\/p>\n\n\n\n

Easy focusing<\/h3>\n\n\n\n

The focuser moves the main mirror, giving you ample focusing options. That means you have no problem using eyepieces, cameras and other accessories. Handy if you want to expand later.<\/p>\n\n\n\n

Ideal for anyone who likes to observe on the go<\/h3>\n\n\n\n

Because it is light and compact, take it with you on vacation or an evening of stargazing out of town. You don't need to be strong or have much experience: aiming and watching is enough.<\/p>\n\n\n\n

What to expect<\/h3>\n\n\n\n

\u2713 Moon: sharp craters, clear shadows
\u2713 Planets: nice contrast details, even at higher magnification
\u2713 Nature observation: quiet, tight image
\u2717 Deep-sky: limited to bright objects
\u2717 Low magnification widescreen: not ideal due to long focal length<\/p>\n\n\n\n
