Omegon Pro APO AP 104/650 Refractor - The flagship for astrophotography
The Omegon Pro APO AP 104/650 Refractor is a compact, powerful apochromatic. It reproduces colors faithfully and delivers exceptional contrast. The triplet lens with Ohara glass from Japan ensures sharp stars all the way to the edge of the field of view. Even at high magnifications, every detail remains razor-sharp. This is the ideal partner for those who want to take beautiful astrophotos.
Triplet optics for stunning images
The combination of FPL-53 and FPL-51 elements completely eliminates color errors. Planets, star clusters and nebulae come into focus bright and contrasty. Compared to mirror systems, this refractor offers unmatched sharpness and intensity, especially for fine contrast differences.
2.9″ focuser for full exposure
The hybrid focuser ensures that every camera gets a fully exposed image. The diagonal gearing keeps heavy cameras steady, while the 1:10 microfocus focuses precisely and smoothly. The 360° rotation makes it easy to adjust the angle of your camera, ideal for elongated objects or panoramic shots.
Versatile connections
The focuser supports 2″, 1.25″ and M74 connectors. You connect eyepieces, adapters or full-frame cameras without losing image quality. With the optional image field equalizer, you can make stars sharp all the way to the edge of your sensor. This creates photos with a completely flat field of view.
Sturdy and travel resistant
The CNC-machined tube has a black velvet shielding system against reflections. The retractable dew hood keeps condensation at bay, and the aluminum transport case protects the refractor from dust and shock. Ready for use wherever you go.
