Top-of-the-range for your eyes: Omegon Pro APO with >0.95 Strehl
Welcome to the premier league of refracting telescopes! The Omegon Pro APO 90/540 offers the highest optical performance and robust mechanics. It allows you to get the very most out of every night of observation – without compromise. Chromatic aberration, loss of contrast and image blurring are a thing of the past with this triplet.
Advantages at a glance:
- Objective lens with premium ED glass: for a colour-accurate, high-contrast image
- 540 mm focal length: ideal for wide-field observations with maximum sharpness and a large field of view
- 3.7" focuser with reduction gear: supports even heavy diagonal mirrors and binocular heads
- High-quality case: protects the instruments during transport
- Sturdy tube clamps with Vixen-style rail: for a secure fit
Top-class optics with certification
With the Omegon Pro APO 90/540, you know exactly what you’re getting: tested quality. An included interferometer test certifies the virtually perfect image quality. Every detail reaches your eye with maximum sharpness.
Crystal clear: triplet with ED
The three-element objective is fitted with top-class low-dispersion ED glass. This gives you a clear and colour-accurate image that looks fantastic even with bright stars or Planets. The sharpness is far superior to that of standard off-the-shelf apochromats, which you may be familiar with from your own observations. Even greater care has been taken in the design of the optics for this model. Because every detail counts when observing.
An Allround visual telescope with a 540 mm focal length
The 540 mm focal length is ideal for visual observation, but also for astrophotography, where higher resolution is key. You can trace the fine structures on Jupiter. You can observe delicate nebulae in the deep sky. Or photograph globular clusters and smaller planetary nebulae. This refractor offers the right performance for both. At the same time, it remains compact enough for portable use on high-quality mounts.
Sophisticated mechanics: focuser, accessories, transport
The solid 2.5-inch focuser with reduction gear holds even heavy accessories precisely in position: from the diagonal mirrors to the wide-field binocular head. The integrated rotator ensures a comfortable view regardless of the tube’s position. An integrated viewfinder shoe and a sturdy carrying handle are included in the scope of delivery. High-quality tube clamps with a Losmandy rail make assembly easy. The included case protects your instruments during transport. So you’re always ready for the next clear night.
Solid connections down to the last detail
The instrument features centre-clamping mounts for 1.25" and 2" accessories – ensuring that expensive and heavy accessories are held precisely and securely. Photographic accessories can be screwed into the focuser via the 82x1mm internal thread.
