Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
NOTE: This item is a used or returned product. This means: The item may show slight signs of use; some accessories may be missing; the packaging may differ from the original packaging. Please note that refurbished items generally come with a 12-month warranty.
Ultra Light Dobsonian 254mm GENERATION II - with completely redesigned and improved construction.No telescope type has influenced amateur astronomy as radically as the
dobsonian telescope. Before the introduction of this telescope type by
John Dobson the vast majority of amateur telescopes were small
inadequate refractors on shaky mounts - just good enough to show the
polar regions on mars or the rings of Saturn. Bigger telescopes, like
the Schmidt-Cassegrain telescopes, were restricted to the relatively
small group of amateurs that could afford them.The brilliant combination
of simple - but effective - mechanics and the largest aperture
available led to a worldwide triumph of this concept. No other telescope
type offers you so much light for your money as a good dobson. We have
taken the motto "held together by gravity and driven by yoghurt power"
and offer a modern version of the classic - designed by amateur
astronomers for amateur astronomers. Despite its large aperture the
telescope can be transported easily even in small cars and is assembled
within minutes without tools. The construction was optimized for maximum
rigidity with a minimum of mass. The combination of big altitude wheels
and a optimized aluminium-sandwich construction allows for small
movements even at high magnifications. The focus position is already
positioned to accept our coma-corrector. The ideal workhorse for the
deep-sky enthusiast. A telescope with 254mm aperture gathers more than
1300-times more light than the naked eye. Details on planetary surfaces
stand out even to unexperienced observers, and countless deep-sky
objects show details. Bright globular clusters are resolved down to the
core and the view of the lunar terminator will provide a unforgettable
experience.Dimensions for mobile use: Rockerbox 395mmx395mmx310mm; Mirrorbox 330mmx330mmx295mm; Trusses approx.700mmEyepiece Height while pointing at zenith approximately 1,15m; 10“ Net total weight: 26,4 kg; 10“ Mirror Box: 14 kg; 10“ Secondary cage +Rockerbox: 9,7kg; 10“ 4 Pairs of trusses: 1,5kg; 10“ Altitude Wheels: 1,2kg ; Focuser thread: M54 x 0.75 mm.

The new BRESSER Nebula 5 EQ/AZ Wifi-Network Mount is a precise and quiet telescope mount – ideal for astrophotography. The controller box offers numerous central connectivity options for various accessories such as cameras, filter wheels, and motor focusers via USB (2.0/3.0), simplifying the setup of a professional astrophotography machine.
BRESSER has relied on innovation coupled with quality Made in Italy for this top-notch product. The manufacturer's long experience in mount construction guarantees a high-end device with first-class functionality and utmost reliability. Additionally, the in-house development team in Italy ensures quick response times in technical support and the adaptation of new device drivers. Truly, "Professionals at work!"
The mount is controlled via pre-installed web-app software, accessible via WIFI and Ethernet cable connection. The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a standard PC, which can be remotely controlled via a smart device such as a mobile phone or tablet. However, this does not exclude the traditional use of computers of all types and brands, which can be connected to the system either wired or wirelessly.
The BRESSER Nebula GoTo System Controller is a Raspberry Pi 4 microcomputer, which allows complete control of the setup (mount, camera, etc...) without the need for any other external device. The BRESSER Nebula GoTo system comes equipped with all Linux-based applications required for performing all astrophotographic functions.The existing INDI environment allows for the control of almost all devices (cameras, filter wheels, rotators, etc., including observatory domes) needed for local or remote astrophotography sessions.
The system also offers high flexibility for users who prefer to use traditional computer client applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools. This complete compatibility is ensured through the adoption of the Alpaca communication protocol, which allows for the use of traditional ASCOM platform drivers for native INDI devices.State-of-the-art mount construction
The BRESSER Nebula mounts are CNC-manufactured from stainless steel and aluminium. The sleek and functional design is courtesy of a renowned Italian mount manufacturer, who has licensed the design and now manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily portable mount, which despite its light weight of only 13 kg (incl. tripod), allows for a high load capacity of up to 20 kg.Visual Observation
For visual observation and direct use, control the mount with the hand control box included in the package. Alternatively, connect the Nebula 5 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be set via the web application. The user interface is deliberately simple and clear to ensure intuitive operation.Astrophotography
Here, the Nebula mount shows its full strength. Whether mobile or stationary, the capability for remote operation is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transmission) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed Kstars/EKOS software to control the mount and all external devices such as cameras, motor focus, filter wheel, etc. Alternatively, you can also directly control the unit with your own software. Applications such as Cart du Ciel (Star Chart), TheSkyX, SkySafari, Stellarium, and other planetarium programs as well as SGP, Nina, CCD Ciel, and other astrophotography tools can be used without any issues.2-in-1 Mount with EQ and AZ Mode
If required, the Nebula can be switched from the equatorial mode to the azimuthal mode. This is particularly advantageous for observing nature or tracking satellites. Thus, the mount can be used for various applications and is not limited to astronomy.Attachment of up to two optics
Would you like to adapt multiple optics? No problem. Simply use the option to replace the counterweight bar with another telescope. Use the second optic as a counterweight to the main telescope. Set the Nebula 5 to azimuthal mode, remove the counterweight bar, and screw a suitable second telescope clamp directly onto the mount.
