Omegon Pro AP 40/180 Refractor - ultra-compact apo for great astrophotos
The Omegon Pro AP 40/180 is made for astrophotographers seeking maximum quality in an extremely compact form. This small apochromatic refractor lets you capture the sky in bright colors and tight stars, even with a fast f/4.5 aperture ratio. Ideal when you want to be light, mobile and efficient without compromising on image quality.
Colorful images that make an immediate impression
The quadruplet design with four lenses, including two made of high-quality ED glass, effectively corrects color errors. That means stars stay sharp and nebulae retain their natural tones. You will not see annoying purple edges, but a clean and calm image. This makes your images look professional, even at short exposure times.
Flat field of view ready for modern cameras
The integrated corrector ensures a flat and evenly illuminated field of view all the way to the edges. Even full-frame cameras are neatly served. This saves time in post-processing and ensures that every part of your photo remains usable.
Fast, light and ideal for travel
With its low weight and short tube length, this refractor is perfect for mobile setups, star trackers and compact mounts. You will effortlessly take it with you to dark locations, but it also delivers impressive results from the city. This way, you will make the most of every clear night.
Precise focusing without fuss
The helical focuser makes focusing easy and controlled. Even with heavier cameras, the focus remains smooth and stable. This is important in astrophotography because a small focus error can already be visible in your end result.
