Omegon Pro APO AP 71/490 Quadruplet OTA - 71mm Refractor

Omegon Pro AP 71/490 Refractor - compact apochromatic for serious astrophotography
The Omegon Pro AP 71/490 is built for astrophotographers who want to see more and capture more. This compact apochromatic refractor lets you rediscover the sky, with bright colors and fine details hidden by simple optics. You will notice it immediately: stars remain sharp to the edge and nebulae show their true shapes and structures. This gives you images you can be proud of, even from less dark locations.

Color clean and flat image right out of the box
Thanks to the quadruplet lens design with high-quality ED glass, you will see virtually no color errors. Stars remain point-shaped and nebulae show their natural color gradient. The integrated corrector ensures a flat and well-lit field of view, even when using full-frame cameras. That means less post-processing and more time to enjoy your results.

Why this refractor shows more detail
This apochromatic is designed to maximize contrast. Each lens surface has a high-quality multicoating so that as much light as possible reaches your camera or eye. This produces bright images with clear separation between object and background. On planets, you will see finer structures, and on deep-sky objects, subtle details come out better. This is precisely why many astrophotographers choose this type of optic.

Powerful 2.5″ focuser for heavy-duty cameras
The rugged 2.5″ rack-and-pinion focuser is made for precision work. You focus without jerking, even with heavier cameras and accessories up to about 4 kg. The 1:10 fine adjustment helps you find exactly that focus where stars stay small and sharp. This makes a big difference in long exposures as your image remains stable and sharp.

360° rotation for perfect alignment
Is your object in focus but just misaligned on the sensor? With the 360° rotating focuser, you easily rotate the camera to the correct position without having to refocus. This saves time and avoids frustration during nighttime photo sessions.

Flexible and ready for expansion
The telescope comes as an OTA and is easy to combine with your existing mount. The removable 2″ eyepiece adapter reveals an M64x0.75 thread, so you can use additional accessories without any problem. Everything is designed for flexibility and future-proofing.
