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 aluminum 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.
Features:
- Optical tube with paraboloid primary mirror 200 mm in diameter
- Active cooling of optics for faster temperature stabilization
- Special aluminum coating with a reflectivity index of 92~96%
- High aperture, minimum optical distortion even at extreme magnification
- Dual-speed Crayford focuser for precise focus adjustments
- Universal mounting system: compatible with most mounts
The kit includes:
- Telescope optical tube
- Finder 8x50mm
- Finder scope base
- Dovetail plate
- Tube rings (2 pcs.)
- Extension tube 35mm
- Cooling fan
- User manual and lifetime warranty

Hi! I have a telescope mount from Bresser Messier telescope. The one with steel tripod and with the "MEADE ME5" inscription. Is it suitable for this telescope model?
Customer service:
Yes, this mount is suitable for the Levenhuk Ra 200N F5 OTA.
Leo Kane (2014.11.23)
Hello! I would like to purchase my first telescope to be able to observe astronomical objects. 1. I am not sure which optical design (refractor of reflector) I should choose. 2. Speaking of the telescope's aperture, this telescope seems to be great, but it looks like the kit doesn't include a tripod and eyepieces, so I guess it's not suitable for me cause I'm a beginner... 3. I'm going to observe (most of the time) in the city and use the instrument mainly for observing deep-sky objects. 4. And also I have doubts about shipping... will the package get to Alaska safely??
Customer service:
1. Refractors perform exceptionally well in the city, they successfully cope with urban light pollution. Refractors are perfect for observations of the Moon, binary stars, they are also easy to use. 2. We recommend that you consider Levenhuk Skyline PRO 105 MAK Telescope - http://www.levenhuk.com/catalogue/telescopes/levenhuk-skyline-pro-105-mak-telescope/
. 3. The telescope will be delivered to you safe and sound.

What's the difference between this model and Levenhuk Ra 200N F4 OTA. The last one is much more expensive... why?
Customer service:
The Levenhuk Ra 200N F4 OTA model has a shorter focal length of 800 mm, it's lighter and has smaller dimensions.
max roller (2014.05.18)
Tell me please what's the difference between this tube and Levenhuk Ra 200N Dob Telescope? I mean the price is the same, so...
Customer service:
Levenhuk Ra 200N Dob has a longer focal length of 1200 mm, also it comes with a Dobsonian mount, Plossl 9 mm and SuperView 30 mm eyepieces.
Zack (2014.03.26)
I'm interested in buying this tube... what about mirror quality? Strehl ratio? At least approximately?
Customer service:
Levenhuk Ra telescopes are designed for the most demanding users. The optics quality is at the highest level. Unfortunately calculation of Strehl ratio was not performed for this tube.
Terry (2014.02.21)
Which eyepieces do I need to get the highest practical power?
Customer service:
Consider Levenhuk Ra LER 3 mm Eyepiece: http://www.levenhuk.com/catalogue/accessories/telescope-accessories/telescope-eyepieces/levenhuk-ra-ler-3mm-1-25-eyepiece/
mark baker (2014.01.10)
Hi. Will I be able to maintain the main mirror by myself and what cleaning stuff do I need? Thanks in advance
Customer service:
Yes, you can, if you are totally sure of what you are doing. The mirror can be washed if it get dusty. All you have to do is melt some baby soap in distilled water and churn it. After washing it you should rinse the mirror with clean distilled water and not wipe it, but let it dry in a vertical position so the drops can flow down.
mark baker (2014.01.09)
Hi. Please tell me if this model can be set on the mount from the Bresser Galaxia 114/900 telescope. thanks!
Customer service:
Unfortunately, this mount isn't suitable for Levenhuk Ra 200N F5 OTA.
Bruce Horton (2014.01.05)
What else do I need to purchase to install this tube on the Sky-Watcher EQ5 mount?
Customer service:
Levenhuk Ra 200N F5 OTA is equipped with the dovetail plate tube-mount assembly system. So there's no need to buy anything additionally.
Bruce Horton (2014.01.04)
Is Sky-Watcher EQ5 mount ok for this tube?
Customer service:
Yes, you can install Levenhuk Ra 200N F5 OTA on this mount.
KEVIN HARVEY (2013.12.13)

Customer service:
Please clarify which mount do you have in mind?
Jerry (2013.11.14)
Hi. Is there a eq mount without any control systems and auto guidance for this tube?
