Omegon Pro APO AP 104\/650 Refractor<\/strong> -<\/strong> The flagship for astrophotography<\/strong>
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.<\/p>\n\n\n\n

Triplet optics for stunning images<\/strong>
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.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

2.9\u2033 focuser for full exposure<\/strong>
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\u00b0 rotation makes it easy to adjust the angle of your camera, ideal for elongated objects or panoramic shots.<\/p>\n\n\n\n

Versatile connections<\/strong>
The focuser supports 2\u2033, 1.25\u2033 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.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

Sturdy and travel resistant<\/strong>
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.<\/p>\n\n\n\n

What you see with it<\/strong>
\u2713 Planets: sharp, contrasty, detailed
\u2713 Deep-sky: star clusters and nebulae bright and sharp
\u2713 Nature: birds and distant objects in natural colors
\u2713 Photography: full-frame and APS cameras ready for immediate use
\u2717 Sun: only with suitable sunscreen<\/p>\n\n\n\n
