M68/M86 negativ-negativ Converter (for M68M63M48p Riccardi Adapter to Esprit100/120/150 focuser) This adapter allows M68 accessories to be mounted INSIDE ESPRIT drawers with M86 threads (Esprit100, Esprit-120 and Esprit150). The first step is to screw the M68 accessories into the M68M86n adapter. This can be done from both sides, depending on the intended use (e.g. optics or other adapters). If the M68 accessory is not too wide, the already screwed together unit can be completely countersunk into the eyepiece extension without loss of light path. It is often bought together with the adapter "M68M63M48p" (see photo below), in order to be able to countersink the Riccardi Reducer in the eyepiece extension without tilting.

Masuyama eyepieces are known for their clear and high contrast imaging and velvet black background. The good contrast of these high-end eyepieces is achieved with a special cut, internal diaphragms and the best possible internal blackening. Due to the elaborate lens design, the eyepieces get by with only 5 elements, with good correction at the same time. Despite the large field of view, the short focal length Masuyama eyepieces are highly recommended for planetary and double star observation. At the same time, the eyepieces are of course very nice overview eyepieces for deep-sky observation. The long focal length eyepieces are well suited for finding and observing large area deep sky objects. The eyepieces were developed by renowned optician Dr. Masuyama. Among other things, Dr. Masuyama designed an eyepiece with a focal length of 100 mm, which was used on the historic 60-inch telescope at Mount Wilson Observatory in California. We are pleased to offer you these legendary eyepieces with the latest glass and coating technology. Scope of Delivery: Eyepiece Dust caps

Easier for beginners, certainty for professionals! The completely redesigned and revolutionary collimator version 3.0 for your telescope. The market continues to develop towards short focal lengths and highly sensitive cameras with extremely small pixel sizes. This increases the requirements for a clean telescope alignment. The Ocal collimator is an innovative tool, which facilitates the adjustment in a completely new way. Each Ocal collimator has an internal motor that moves the CMOS chip linearly. Via the software, the focus can thus be ideally adjusted to the individual areas of the alignment. So you can focus on any area in the telescope without touching the setup or imagetrain. Colored centering circles can be selected and adjusted via the included software. The software also controls the line width of the circles as well as the contrast and exposure of the live image. Last but not least, a fade cross can be switched on and rotated via software. In this way, all areas that are important for the adjustment can be brought into focus and concentrically aligned very precisely. With the alignment of the crosshairs, the exact linear alignment of the trap can be assessed. Scope of delivery: OCAL 3.0 Connection cable 2x adapter Closing cap

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
