Skywatcher AP 120/840 - Bright, clean and made for serious performance

The Skywatcher AP 120/840 is a perfect choice when you are looking for sharpness, color purity and calmness in your image. You will see an immediate difference as soon as you look through this telescope: calm stars, clear details and an image that remains tight even at high magnification. This is a telescope for those who want more than a standard entry-level telescope.

Really clear image without color errors

The Esprit series uses a triplet design with high-quality glass. That means your image stays clean, with no purple edges or distortion. You see more contrast, making fine structures stand out more clearly. This helps you tremendously when viewing planets or nebulae. You need to correct less with your eyes because the image is quiet by itself.

More light, more detail

The opening of 120 mm lets in a lot of light. As a result, objects remain bright even when you zoom in further. You can see sharp edges on the moon, fine cloud bands on Jupiter and contrast in bright nebulae. The telescope works intuitively. You aim, focus and see immediate results.

Focuser that gives you control

The 3″ Linear-Power focuser is made for heavy cameras and large sensors. It keeps moving smoothly even when using accessories. You can rotate it so you can quickly find the right camera position. The fine 1:11 setting gives you control over the last millimeters of sharpness. This makes it much easier to get a perfectly sharp image, both visually and for photographs.

For visual and photography

This telescope works great for those with visual viewing as well as those who want to take pictures. You get clarity, color purity and mechanical stability all in one package. Your image remains tight even when using higher magnifications or trying longer exposures.
