Omegon Pro APO AP 130/910 – Premium 130mm Triplet Refractor

The Omegon Pro APO AP 130/910 is a premium 130mm f/7 triplet apochromatic refractor developed for astronomers who demand exceptional sharpness, contrast and colour correction.

Combining a 130mm ED triplet objective with a versatile 910mm focal length, precision 3.7-inch focuser and certified optical performance, this is a serious refractor for high-resolution lunar and planetary observing, visual deep-sky astronomy and astrophotography.

Each instrument is supplied with an interferometric optical test report documenting a Strehl ratio of at least 0.95, providing confidence in the optical performance of the individual telescope.

130mm ED Triplet Optics

At the heart of the Omegon Pro APO 130/910 is a three-element apochromatic objective incorporating premium ED glass. The optical design is engineered to suppress chromatic aberration and produce naturally coloured, high-contrast views around bright stars, the Moon and planets.

With 130mm of aperture, the telescope provides enough resolving power for detailed planetary observation while gathering sufficient light for globular clusters, planetary nebulae and many smaller deep-sky targets.

• 130mm aperture
• 910mm focal length
• f/7 focal ratio
• ED triplet apochromatic objective
• Fully multi-coated optics
• Individual interferometric optical test
• Documented Strehl ratio ≥0.95

Optimised for the Moon and Planets

The combination of 130mm aperture and 910mm focal length makes this Pro APO particularly attractive for detailed lunar and planetary work.

Its f/7 optical system provides a useful balance between resolution, image scale and overall tube length. Under good seeing conditions, the telescope is capable of revealing subtle lunar structure and fine planetary detail while maintaining the clean colour correction expected from a high-quality apochromat.

The telescope has a quoted maximum useful magnification of approximately 260x, although actual usable magnification will always depend on atmospheric conditions and the target being observed.

More Than a Planetary Refractor

The 130/910 is also a highly capable all-round astronomical instrument. Its aperture makes it suitable for double stars, globular clusters, planetary nebulae and brighter galaxies, while the excellent contrast of a refractor can reveal subtle structure in deep-sky objects under dark skies.

For astrophotography, the longer 910mm focal length offers increased image scale compared with shorter wide-field astrographs, making it particularly useful for smaller nebulae, galaxies and high-resolution imaging projects.

3.7-Inch Precision Rack-and-Pinion Focuser

A premium optical tube needs equally capable mechanics. The Omegon Pro APO 130/910 uses a substantial 3.7-inch rack-and-pinion focuser with 1:10 fine focusing.

The fine-focus reduction makes precise focusing considerably easier at high magnification and when imaging with modern astronomy cameras.

The focuser is also rotatable, allowing you to position an eyepiece, diagonal or imaging camera more conveniently without rotating the entire optical tube.

• 3.7-inch rack-and-pinion focuser
• 1:10 fine-focus reduction
• Rotatable focuser
• 100mm focus adjustment range
• Approximately 150mm back focus
• 1.25-inch and 2-inch accessory support

Secure 1.25-Inch and 2-Inch Accessory Mounting

The telescope provides self-centring connections for both 1.25-inch and 2-inch accessories, helping keep diagonals, eyepieces and other equipment securely and accurately aligned.

For astrophotography, an M82x1 internal thread provides a substantial threaded camera connection and helps avoid unnecessary restriction in the imaging train.

Built for Serious Astronomy

The aluminium optical tube is supported by robust metal tube rings and a Losmandy-style dovetail rail, providing the secure mounting platform expected for a refractor of this size.

A carrying handle makes installation easier, while an integrated Vixen/Sky-Watcher style finder shoe provides a mounting point for compatible finderscopes and accessories.

Individually Tested Optical Quality

One of the most important features of the Omegon Pro APO AP 130/910 is its documented optical quality.

Each telescope is supplied with an interferometric test report documenting its optical performance, including a Strehl ratio of at least 0.95. This provides considerably more information about the individual instrument than relying on model specifications alone.
