Omegon 66/400 Pro APO ED OTA: FPL-53 in travel format
The Omegon 66/400 Pro APO ED weighs only 1.6 kilos and yet carries FPL-53 glass: the reference material for color-pure refractors. This makes it the ideal tube for travel trackers like the Star Adventurer and for anyone looking for an ultra-light widefield system that can also keep up visually and for nature observation.
An apochromat converges all colors to a focal point. Stars remain white and point-like, without the purple edges of simple lenses: precisely what a camera sensor would mercilessly reveal.
2 inch Crayford with rotation
The 2-inch Crayford focuser features micro-focusing and rotates 360 degrees, allowing you to rotate the camera to any framing without releasing the clamp. With an optional flattener, the field is suitable for full-frame.
The f/6 optics are versatile: wide enough for large nebulae, sharp enough for the Moon and double stars with an eyepiece in it.
Complete with case and clamps
Two tube rings, dovetail and transport case are included: pack and go. During the day, with an amici prism, this is also an excellent spotting scope, and with a properly certified solar filter, a compact solar telescope. Never look or photograph toward the sun without a certified solar filter: that causes permanent eye injury and damage to your sensor within a second.
Included
- ED doublet 66/400 with FPL-53 glass
- 2-inch Crayford focuser with dual-speed adjustment and 360-degree rotation
- Two pipe clamps with dovetail
- Transport case
Featured accessories
The Omegon Powerbank 10k 12V (39.90 euros) powers the tracker and camera on the go. For visual use, the Omegon 7-21 mm zoom eyepiece (69 euros) provides continuously variable magnification from 19x to 57x, and an Omegon Premium Moon filter (19.90 euros) dims the bright Moon.
For whom yes, for whom no
Good for: traveling astrophotographers and anyone looking for a lightweight all-in-one system for the sky, nature, and the sun with a filter. Not for: those who want a larger aperture for smaller objects; the 80/500 Pro APO Carbon is the logical step up. Are you hesitating between the models? The Choice assistant helpt.
