Omegon Dobson telescope Push+ N 203/1000 Your smartphone phone and this telescope are now 'best friends Experience a whole new feel to exploring the night sky with this Omegon 8 inch Dobsonian telescope together with the Push+ object locator. This telescope can find any planet or deep sky object in the twinkling of an eye! This is made possible by the intelligent Push+ object locator - the telescope communicates instantaneously with your smartphone! The advantages in a nutshell finding newly invented - you can now located any object in the night sky using the Push+ object locator and your smartphone built-in digital encoder - your telescope immediately knows where it is pointing. The software allows you follow every step and locate objects in a jiffy. Bluetooth 2.0 provides a wireless connection to your smartphone - with a range of 10 meters smartphone holder - suitable for all smartphones with a width of up to 75mm software - take control of your telescope with the SkySafari® 4 Plus app for Android, or use programs such as Cartes du Ciel® or Stellarium® with your PC GP receiver - mounts any telescope with a GP rail The optics - high contrast and sharp images thanks to the parabolic mirror Good optics are the heart of any telescope - the 203mm parabolic main mirror here provides a sharp image right out to the edge of the field of view, for a visual experience where you might forget that you are still on Earth and are only 'travelling' with your eyes. A journey into the past - getting into the world of galaxies 203mm of aperture lets you enter a whole new domain - that of the 'deep sky objects', or DSOs. You can observe globular clusters thousands of lightyears away, sparkling like a million diamonds in your telescope. Or even galaxies - 'islands of stars' like our Milky Way. You can observe the following objects with the telescope globular clusters planetary nebulae galaxies open clusters hydrogen nebulae planets, comets and much, much more. Omegon Dobsonians open a new door to the universe - the main mirror in this telescope gathers 75% more light than a 150mm telescope. You can explore hundreds of objects in the night sky. Digital Encoder - a 'satnav' for your telescope Know where you are - the digital encoders on the azimuth and elevation axes tell you just where you are in the night sky at all times. This technology, which is used on large equatorial mounts, is now also employed with this Dobson telescope. But all this would be nothing without a good controller - and this you already have! Smartphone - your way to the stars Your Android smartphone now allows you to keep track of everything yourself - the Sky Safari® 4 Plus astronomy app for Android systems turns your phone into a control centre for your telescope. The coloured display on your smartphone shows the current region of the night sky and allows you to select an object you wish to observe. You can then move the telescope to the target in a jiffy - as you move the telescope in the direction required, you will see a crosshair moving across the star chart. With the right app it's easy You can purchase the SkySafari® 4 Plus app at Google Play. Push+ will not work with Apple iPhones or iPads (iOS operating system) - a separate version for these is due to be released in 2017 Is there also another way that doesn't need a smartphone? Yes, there is! - you can use Stellarium® or Cartes du Ciel® planetarium software. Simply install one of these free programs on your laptop - and off you go, wirelessly, to the stars. Whether smartphone or PC - a Bluetooth 2.0 connection is used to communicate with the telescope. GP receiver The rocker box has a receiver for Vixen style GP rails. This means you can connect most telescopes with GP rails to the rocker box and benefit from the Push+ system. This works best with Newtonian reflector telescopes of up to 8 inches in diameter. Ensure your exploration of the night sky is always successful with Push+. Note: smartphone and App are not included. Our expert comment: The Push+ object locator is also available as a mount (rocker box) with GP receiver for your own telescope OTA (for up to 8 inches aperture). In the box: Tube Rockerbox 2x eyepieces 10mm, 25mm Kellner Red dot finder

Omegon Mount Mini Track LX2

Item condition: new and original packed

Manufacturer's product description: Motor drive suitable for the following telescopes : Omegon 150/750 EQ-3 Teleskop Omegon 76/900 EQ-2 Teleskop Zoomion Gravity 150 EQ Omegon EQ-3 motor drive - the motor drive for your Omegon EQ-3 telescope It is clear starry night. An object is in the field of view - perhaps the planet Jupiter - you note how the planet slowly moves in the field of view. You continually have to use the manual slow motion controls of your telescope to get the object back into the centre of the field of view. But this is also possible automatically Use the simple method of employing a tracking motor with your Omegon EQ3 mount. This will save you having to constantly adjust the telescope by hand. Once attached, you will then be able to concentrate much better on your observing. The motor relieves you of this irksome burden and will track your telescope in synchronisation with the movement of the stars from now on. The object you are observing will remain permanently in the field of view when the motor is operating! Even more features You also receive a handbox for controlling your telescope with the Omegon EQ-3 motor drive. Four large keys provide 8x and 2x tracking speeds and for temporarily stopping tracking. This means you can also follow objects at higher speeds and keep them positioned in the field of view. There is also an ON/OFF switch and a switch for selecting which hemisphere you are on. This means that the Omegon RA tracking motor can be used anywhere in the whole world. The handbox is ergonomically designed so that it is easy and safe to use even when wearing gloves. The advantages in a nutshell: RA axis motor for automatic tracking drives the main axis of the telescope well suited to visual observing comfortable to use: manual adjustment is no longer necessary straightforward assembly, only taking a few minutes handbox for 2X and 8X tracking speeds switch for northern and southern hemispheres It's a clear starry night. The object is located in the field of view, the planet Jupiter perhaps. You watch how the planet rapidly moves out of the field of view. The manual slow motion controls of your telescope allow you get the object back into the field of view... This is also possible automatically Take the easy way and use the tracking motor for your Omegon mount. It saves you constantly having to adjust the position of the telescope by hand. Simply connect it up and you can concentrate on observing. The motor now does all the work, and from now on will move your telescope at exactly sidereal speed. The object remains permanently in the field of view, as long as the motor is running! Yet more features Along with the Skywatcher motor, you will also get a hand box for controlling your telescope. Four large buttons are used for 8X and 2X sidereal speeds, and there is also a pause button. This enables you to move an object into position in the field of view at a higher speed. In addition to the ON/OFF switch, there is a switch for selecting which hemisphere you are located in. This means the Omegon RA tracking motor will work anywhere in the world. The hand box is easy to hold and operate, so you are always in control even with gloves on. The advantages in a nutshell: RA axis motor for automatic tracking powers the main axis of the telescope suitable for visual observing easy operation - manual tracking no longer necessary easy installation which takes only a few minutes hand box for 2X and 8X speeds switch for Northern and Southern hemispheres battery compartment, with cable, for six D batteries

Product description: Omegon premium Moon filter - to ensure that your lunar observing is fun Does the Moon appear far too bright when observing it through your telescope? The Omegon Moon filter reduces the brightness and increases contrast. It screws easy into your eyepiece, permitting relaxed observing and stopping the Moon from dazzling you. The advantages in a nutshell: Omegon neutral density filter - tones down moonlight for more comfortable observing neutral image - the Moon retains its natural appearance high contrast - discover thousands of craters and fine structures for your eyepiece - fits onto any 2" eyepiece with a filter thread The Moon is too bright - tone it down a bit The Moon can be so bright that you can easily read a newspaper by its light at night. But anyone looking through a telescope will note just how bright the Moon really is. It often irritates the retina and dazzles the eye in unpleasantly. No wonder - the full Moon is 25,000 times brighter than the brightest star in the night sky. So having a neutral density filter is definitely an 'ace up your sleeve' when observing the brighter lunar phases. Filter with 25% light transmission This filter is ideal for smaller and medium-sized telescopes up to a diameter of 150mm. The 25% light transmission reduces the brightness of the moonlight, allowing you to observe the Moon at any time - in comfort and without glare. Polished glass for a clear view You are purchasing a first class product with the Omegon Moon filter - a polished glass filter held in an anodised aluminium mount. The filter glass has been ground and stained throughout the entire glass volume. This avoidance of using a superficial coating means that it cannot wear out, even after many years of use. A Moon filter belongs in the eyepiece case of every amateur astronomer. But, above all, it is a must for comfortable lunar observing.

The Skywatcher 0.85x focal reducer / field flattener has been designed for astronomers who want to use the renown ED Apo for astro photography. The flattener reduces the telescope's focal length by the factor of 0.85 and increases the useful field. As a positive side effect, the necessary integration times are significantly reduced. The field curvature that is unavoidable at most telescope systems is reduced to a nearly irrelevant level when using sensors up to APS-C format (24x16mm). Optimal distance M48 - focal plane: 55mm
