Description
Levenhuk Ra 200N F5 OTADescription Levenhuk Ra 200N F5 OTA is an optical tube for deep space exploration. This is a powerful and high aperture Newtonian reflector that can be used for both visual observations and astrophotography. This Optical Tube Assembly (OTA) will be a real catch for any amateur astronomer, as you can see many nebulae, galaxies and star clusters with it as well as lunar craters, dust storms on Mars, Saturns rings, and even the Galilean moons of Jupiter.
Description
Levenhuk Ra 200N F5 OTA is an optical tube for deep space exploration. This is a powerful and high-aperture Newtonian reflector that can be used for both visual observations and astrophotography. This Optical Tube Assembly (OTA) will be a real catch for any amateur astronomer, as you can see many nebulae, galaxies and star clusters with it as well as lunar craters, dust storms on Mars, Saturn’s rings, and even the Galilean moons of Jupiter. You can observe many astronomical objects in detail.
The optical design of the telescope is based on the primary mirror with a 200mm diameter. It is covered with aluminium coating. Its reflectivity index is 92~96%. The transmitted image is crisp and clear, and optical distortion does not appear even at the maximum magnification. There is a cooling fan on the back of the telescope tube. It almost doubles the temperature stabilization of optics. It makes it possible to equalize the temperature of the mirror with the ambient temperature much faster than it happens in other telescopes. This is important if the OTA is stored in a warm room and is taken outside for observation. The fan is powered by batteries (purchased separately).
The sharpness is adjusted more smoothly and precisely in comparison with entry-level models. The reason for this advantage is a dual-speed Crayford focuser.
The optical tube has a standard set of mounts, so it can be installed on most modern mounts.
Please note: Mount, tripod, and eyepieces are not included.
