Levenhuk Ra 250N Dob Telescope

Levenhuk Ra 250N Dob Telescope is a Newtonian telescope with an aperture of 254 mm (10 in) and a focal length of 1255 mm (49.4 in). Even if you are just thinking about getting into stargazing, this telescope is a perfect choice - it is extremely easy to assemble and control, thanks to the design of the Dobsonian mount. The Dobsonian mount is very easy to assemble - the kit already includes everything you will need to assemble it. The optical tube is placed into two slots on the assembled mount and is then locked in place with two springs. As soon as that is done, you can begin your observations.

The optical elements are made of BK-7 glass that yields sharp high-quality views. The optical tube has a built-in fan that cools the primary mirror and protects it from deformation, which further adds to the quality of the produced views.

Levenhuk Ra 250N comes with a dual-speed Crayford focuser that provides for precise focusing with no backlash. The focuser accepts 1.25" eyepieces (2" eyepieces will require an adapter), and its compression ring allows you to attach accessories in a matter of moments. The use of roller bearings in the azimuth slow-motion control provides for smooth and precise movements of the mount.

The large aperture of Levenhuk Ra 250N Dob Telescope - with the addition of the wide-FOV SuperView eyepiece (included in the kit) - allows you to observe star clusters, galaxies and other deep-sky objects. If you want to observe the Moon and Solar System planets, just switch from the SuperView eyepiece to 9-mm Plössl, and you will be able to see the tiniest details in lunar craters, and study the surface of Mars and even Saturn.

The Dobsonian mount is shipped unassembled.

Ivan Ayers (2015-01-06 02:33):
Does the difference in dimensions between Levenhuk Ra 300N Dob and Levenhuk Ra 250N Dob have any importance? Levenhuk Customer Service:
Levenhuk Ra 300N Dob Telescope features large objective lens diameter then Levenhuk Ra 250N Dob Telescope. Therefore, the maximum useful magnification of the first model will be higher.

Ivan Ayers (2014-12-10 09:29):
Hello! Tell me please what is the objective lens diameter of this telescope? Is it 254mm or 250mm? Levenhuk Customer Service:
The objective lens diameter of the Levenhuk Ra 250N Dob telescope is 254mm.

Walter Carson (2014-09-10 06:58):

Hello, how is this model different than Levenhuk Ra 200N Dob (https://www.levenhuk.com/catalogue/telescopes/levenhuk-ra-200n-dob/)? Which one is better? Levenhuk Customer Service:
The main difference between Levenhuk Ra 250N Dob and Levenhuk Ra 200N Dob is primary mirror diameter (aperture). The Levenhuk Ra 250N Dob is a preferred choice due to larger primary mirror diameter.

Amy Larson (2014-08-08 02:44):
Hello! I wanted to ask you which eyepiece would allow me to achieve the highest practical power of this telescope? Levenhuk Customer Service:
To achieve the highest practical power of the Levenhuk Ra 250N Dob telescope we recommend using 2.5 mm eyepiece. Unfortunately such accessory is unavailable in our store at the moment.

Ramon (2014-06-16 06:53):
When will the telescope be in stock? Which similar models (not less than 250-300mm) would you recommend? Levenhuk Customer Service:

Warren Swanson (2014-06-11 09:14):
Greetings! I bought this telescope, which eyepieces are better for planetary observations? Someone recommended me to buy wide-angle eyepieces... is it a good advice? Levenhuk Customer Service:
Yes, the use of wide-angle eyepieces is preferred.

Daniel (2014-06-09 05:28):
I can see there is some kind of a cross inside the tube... will I see it when observing? Levenhuk Customer Service:
Don't worry, you won't see it, only high-quality image of observed object with no distortions.

Jeff Parker (2014-05-21 11:33):
I apologize for this silly question, but why it is needed to cool the telescope mirror? Levenhuk Customer Service:
Cooling the telescope mirror significantly reduces time of optics thermal stabilization. Thanks to the built-in fan the primary mirror quickly reaches thermal equilibrium with the environment.

Tim Suarez (2014-04-11 07:13):
Where can I fing user manual in english for this model? I haven't found it in the box. Levenhuk Customer Service:
You can download the user manual in the 'References and Downloads' section.

Randall (2014-02-26 06:55):
Hi! What should I buy to use Canon EOS 600d camera with this telescope? Levenhuk Customer Service:
You need camera adapter. For instance Levenhuk 2x Barlow Lens with Camera Adapter: https://www.levenhuk.com/products/levenhuk-barlow-lens-2x-adapter/. T-ring for Canon cameras is also required.

Warren Mann (2014-02-13 11:01):
what's the eyepiece to get the maximum magnification? Levenhuk Customer Service:

Norman Merrill (2013-12-28 05:20):
Hello! Tell me, please, which telescope is more suitable for observing the starry skies and terrestrial objects from the distance of 500 meters and more. It should have high focal ratio and of course wide field of view. The price range - 300-900$. and high-quality of course!!! Your help is really appreciated. Levenhuk Customer Service:
For your purposes refractors and catadioptric telescopes will suit greatly. Please consider this model: Levenhuk Strike 1000 PRO Telescope - https://www.levenhuk.com/products/telescope-levenhuk-strike-1000-pro/

Gary Palmer (2013-12-13 10:51):
Hello! Which Barlow lens you would recommend me to buy additionally? How to achieve the maximum useful magnification? What objects can I observe at this magnification? Thank you. Levenhuk Customer Service:
To achieve the highest practical power we recommend you to use the eyepiece with 2.5 mm focal length. Barlow lenses in this case are not required. Here you can find a list of celestial objects you can see with a telescope based on its aperture - https://www.levenhuk.com/articles/things_you_can_see/

Dawn Sandoval (2013-11-14 05:45):
Can I mount this telescope on Levenhuk Ra EQ5 GoTo? Or equip it with the auto guidance system somehow? Levenhuk Customer Service:
Levenhuk Ra 250N Dob telescope doesn't have fasteners required for it to be installed on Equatorial mounts. Currently we don't have motors for automatic guidance for dobsonian telescopes.

Irene Sherer (2013-09-03 01:21):
Good evening! I don't understand anything in telescopes and astronomy, but I'm craving this telescope! I've been looking and comparing all day long and chose two models: this one and the Levenhuk SkyMatic 135 GTA. Which one would you recommend only for celestial observations (astrophotography is not needed), as I understand, with the first one I will be able to see more, but with the second - less, but without any problems. Levenhuk Customer Service:
The main advantage of Levenhuk Ra 250N Dob is larger objective lens diameter: the greater the aperture the more detailed images a telescope provides. On the other hand Levenhuk SkyMatic 135 GTA has an advanced auto guidance system, which with no doubt will be of a great help when navigating to and tracking celestial objects.

Gina (2013-05-31 01:20):
Tell me, what filters are suitable for deep space observing? or I can use the ones you mentioned before? Levenhuk Customer Service:
For deep-sky observations we recommend: https://www.levenhuk.com/products/filter-levenhuk-ra-uhc-1-25/ https://www.levenhuk.com/products/filter-levenhuk-ra-o-iii-1-25/ https://www.levenhuk.com/products/filter-levenhuk-ra-h-beta-1-25/

Gina (2013-05-30 09:50):
Hello! Tell me, what accessories should I buy with this telescope for observing planets, as well as deep-sky objects (including The Sun) so I wouldn't have any problems and I could get maximum satisfaction right away? Levenhuk Customer Service:
Please, pay attention to the following eyepieces: https://www.levenhuk.com/products/eyepiece-levenhuk-ra-ler-3/ https://www.levenhuk.com/products/eyepiece-levenhuk-ra-er20-wa-12/. The set of filters: https://www.levenhuk.com/products/com-filters_f4_solar_system_set/
