Compact design with impressively wide image
The Skywatcher AC 102/500 AZ-3 gives you a bright, wide and high-contrast image. You immediately see more than with smaller entry-level models, because the 102 mm lens catches a lot of light. Point it at the Moon, a star cluster or a bright nebula and you'll immediately see why this telescope is so popular. The short focal length makes for a large field of view, making it easy to navigate and find objects quickly.

Widefield for relaxing watching
The large field of view makes viewing feel like stepping into space. You can see star fields at a glance, without much searching. That makes this telescope ideal for beginners who want quick results. The images remain clear and sharp, making it easy to recognize objects. Perfect if you like to discover new things in a relaxed way.

Clear, sharp and surprisingly detailed
The 102 mm lens gives you more detail than classic 70 mm starter models. The Moon shows sharp edges, deep shadows and clear craters. Bright nebulae such as Orion become visible in shape and texture. You can also look at Jupiter and see the four moons along its orbit. The telescope keeps the image stable and bright, so you mostly need to look and enjoy.
Modern finishes in the BlackDiamond series
The tube looks stylish thanks to the BlackDiamond finish. The metallic sheen gives it a professional look. So you not only have a good image, but also a telescope that looks nice when you put it on.
AZ-3 mount for smooth and precise tracking
The AZ-3 is a simple and stable mount. You move the telescope smoothly in all directions, making it easy to track objects. The fine adjustment lets you steer accurately without jerking. No need to learn complicated systems; just point, focus and watch. The aluminum tripod is adjustable and stands firmly on any surface.
Ready to use immediately
You get eyepieces, a zenith mirror and a viewfinder, so you can get started right away. With its low weight, you can easily take the set to garden, balcony or dark place. Everything works intuitively, even if this is your first telescope.
