Warning notes
  • General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
  • 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.
  • Do not expose the device to high temperatures.
  • BATTERY WARNING AND SAFETY Safe handling and use of batteries and accumulators Read and follow these instructions before using the battery or accumulator. To the extent permitted by law, failure to comply with these warnings and instructions may result in any damage caused to your product not being covered by the warranty. In this document, the term "batteries" also includes accumulators. Follow these instructions to ensure optimal safety and performance: DO NOT use counterfeit batteries in products. Only use supplied batteries. Use the battery SOLELY for its intended purpose. Keep batteries out of the reach of children and pets. DO NOT use batteries that appear to be damaged, swollen, or modified. Do not use batteries that are leaking, emitting a smell, swollen, melted, or showing dents, rust, cracks, or scratches. The battery should NOT be disassembled, crushed, punctured, shredded, or otherwise tampered with. The battery should NOT be exposed to liquids. Liquid may penetrate the battery's circuits, causing corrosion and compromising its safety. A wet or damp battery should NOT be dried with a device or heat source (e.g., hairdryer or microwave). The device or battery should NOT be placed near a heat source or direct sunlight. High temperatures can cause the battery to swell, leak, or malfunction. Examples include placing the device near a radiator, stove, kitchen appliance, iron, fireplace, or inside a vehicle or next to a window in direct sunlight. The battery should NOT come into contact with metal objects. If metal objects such as jewelry come into prolonged contact with the battery terminals, the battery may become very hot or catch fire.

The battery should NOT be inserted incorrectly when charging. MAKE SURE the battery compartment is empty, dry, and free of dirt before inserting the battery. The battery should NOT be charged in direct sunlight or at extreme temperatures. The battery must be charged at room temperature, typically between 20 °C and 26 °C (68 °F-79 °F). Charging may be temporarily suspended if the battery temperature exceeds 60 °C (140 °F). If the battery is hot but the temperature is under 60 °C (140 °F), the battery will still charge, but more slowly than usual. Avoid dropping the battery or the product with the battery inside. If dropped onto a hard surface, the battery or product may be damaged. If you suspect the battery might be damaged, replace it. Never leave your mobile hotspot plugged into the power supply for more than 24 hours to charge. Let the battery drain and then recharge it. Keeping your mobile hotspot plugged into a charger without draining the battery can damage the battery/device or affect performance. If a battery shows a significantly shorter runtime than when purchased, it has reached the end of its reasonable lifespan. We recommend replacing it. For optimal results and performance, batteries should be replaced after 12 months or earlier depending on usage. Follow local regulations for the disposal of used batteries. Do not throw the battery into fire or water.

BRESSER Messier EXOS 100 GOTO Mount
The BRESSER Messier EXOS 100 GOTO Mount is a complete German equatorial mount for telescopes and cameras. As a GoTo mount, it automatically finds celestial objects and positions the telescope accordingly. It is controlled via a hand controller with display and keypad. With a payload capacity of up to 5 kg, it is suitable for both visual observations and astrophotography. Stable setup for telescope and camera A holder for Vixen-style dovetail plates securely accommodates telescopes or cameras. The stainless steel tripod with height-adjustable legs can be adapted to the respective observing site. A counterweight weighing 2 kg balances the weight of the telescope. A battery compartment for eight C batteries powers the mount independently of a fixed mains socket. Polar alignment made easy An integrated circular bubble level indicates the exact horizontal position of the tripod. An integrated polar finder tunnel enables rough alignment with the celestial north pole. The setting can then be further improved using fine adjustment screws for polar altitude and azimuth. For particularly accurate polar alignment, an optional polar finder scope (Art. No. 0456103) is available. This allows the GoTo function, tracking and astrophotography to work even more precisely. Automatic object search with the hand controller The display and keypad of the hand controller form the central control interface of the mount. For initialisation, you perform a star alignment with one, two or three stars. In doing so, you centre the suggested stars in the eyepiece and confirm the position. After successful alignment, more than 100,000 stored objects are available to choose from, which you can conveniently slew to at the touch of a button. These include planets, constellations as well as Messier, NGC, IC, Sh2 and SAO objects. You can also save your own celestial coordinates and slew to them precisely. Precise tracking for long nights of observation The tracking automatically keeps an object that has been slewed to in the field of view. You can choose between sidereal, solar and lunar rates to suit the respective observing target. Eight different slew speeds are available for manual positioning. A low-noise belt drive with worm gear moves both axes smoothly. Via synchronisation, the mount aligns the position of a known object with the database. The additional RA and DEC backlash compensation calibrates the gear backlash of both axes, ensuring even greater precision. Computer control via USB-C and ASCOM Via a USB-C interface, you can also connect the hand controller to a computer. This allows you to control the mount using ASCOM-compatible programs such as Stellarium or N.I.N.A.. With polar alignment, automatic object search and a stable setup, the mount covers the most important requirements for observation and astrophotography. As a compact GoTo mount, it reliably guides you to tens of thousands of celestial objects. Transform your telescope into a convenient GoTo system with the BRESSER Messier EXOS 100 GOTO Mount. FEATURES German equatorial mount with GoTo function Payload capacity up to 5 kg Control via hand controller with display and numeric keys Holder for Vixen-style dovetail plates 1-, 2- and 3-star alignment for initialisation Access to over 100,000 stored celestial objects Synchronisation and RA/DEC backlash compensation for greater accuracy 8 slew speeds as well as sidereal, solar and lunar rates Low-noise belt drive with worm gear Polar finder tunnel for rough alignment with the celestial north pole Polar finder scope for precise polar alignment available separately (Art.

EXPLORE SCIENTIFIC Camera Dovetail Kit for iEXOS-100 Mount
Universal mounting rail for mounting a photo camera on an EQ mount with Vixen GP mount for astrophotography. The EXPLORE SCIENTIFIC camera dovetail rail is made of die-cast aluminium. The dovetail-shaped mounting rail is 45 mm wide (similar to the Vixen dovetail style) and 280 mm long. The matt black anodized surface has a laser engraved scale on one side with a fine graduation with 2 mm increments. This makes it easier to determine the center of gravity when placing the camera on the mounting head. To protect the clamping surface there is a stainless steel clamping plate on the opposite side. The dovetail plate is equipped with rubber inserts at 3 positions. This allows a secure mounting of the camera equipment and prevents unintentional slipping and twisting. The mounting rail has a screw fastening with 1/4 inch photo thread, which is suitable for almost all commercially available camera systems. The screw attachment can be used in 3 different elongated hole positions to adjust a perfect balance. In addition, an adapter from 1/4 inch to 3/8 inch photo thread is also included, so that ball heads with the larger thread version can also be used directly. The camera mounting rail weighs only 250 grams. Suitable for all EXPLORE SCIENTIFIC and BRESSER mounts and also mounts of other brands that accept the popular Vixen-GP dovetail rail. FEATURES Universal camera mounting rail Dovetail with 45 mm width Length 280mm; weight 250 grams Suitable for EQ mounts with Vixen GP dovetail Camera mounting screw with 1/4 inch photo thread Thread adapter 1/4 inch to 3/8 inch Laser engraved scale with 2 mm fine graduation Stainless steel clamping plate Rubber inserts against slipping and twisting 3 elongated holes for mounting the camera SCOPE OF DELIVERY Camera mounting rail Mounting screw 1/4 inch Thread adapter 3/8 inch

BRESSER Messier EXOS 100 GOTO Mount
The BRESSER Messier EXOS 100 GOTO Mount is a complete German equatorial mount for telescopes and cameras. As a GoTo mount, it automatically finds celestial objects and positions the telescope accordingly. It is controlled via a hand controller with display and keypad. With a payload capacity of up to 5 kg, it is suitable for both visual observations and astrophotography. Stable setup for telescope and camera A holder for Vixen-style dovetail plates securely accommodates telescopes or cameras. The stainless steel tripod with height-adjustable legs can be adapted to the respective observing site. A counterweight weighing 2 kg balances the weight of the telescope. A battery compartment for eight C batteries powers the mount independently of a fixed mains socket. Polar alignment made easy An integrated circular bubble level indicates the exact horizontal position of the tripod. An integrated polar finder tunnel enables rough alignment with the celestial north pole. The setting can then be further improved using fine adjustment screws for polar altitude and azimuth. For particularly accurate polar alignment, an optional polar finder scope (Art. No. 0456103) is available. This allows the GoTo function, tracking and astrophotography to work even more precisely. Automatic object search with the hand controller The display and keypad of the hand controller form the central control interface of the mount. For initialisation, you perform a star alignment with one, two or three stars. In doing so, you centre the suggested stars in the eyepiece and confirm the position. After successful alignment, more than 100,000 stored objects are available to choose from, which you can conveniently slew to at the touch of a button. These include planets, constellations as well as Messier, NGC, IC, Sh2 and SAO objects. You can also save your own celestial coordinates and slew to them precisely. Precise tracking for long nights of observation The tracking automatically keeps an object that has been slewed to in the field of view. You can choose between sidereal, solar and lunar rates to suit the respective observing target. Eight different slew speeds are available for manual positioning. A low-noise belt drive with worm gear moves both axes smoothly. Via synchronisation, the mount aligns the position of a known object with the database. The additional RA and DEC backlash compensation calibrates the gear backlash of both axes, ensuring even greater precision. Computer control via USB-C and ASCOM Via a USB-C interface, you can also connect the hand controller to a computer. This allows you to control the mount using ASCOM-compatible programs such as Stellarium or N.I.N.A.. With polar alignment, automatic object search and a stable setup, the mount covers the most important requirements for observation and astrophotography. As a compact GoTo mount, it reliably guides you to tens of thousands of celestial objects. Transform your telescope into a convenient GoTo system with the BRESSER Messier EXOS 100 GOTO Mount. FEATURES German equatorial mount with GoTo function Payload capacity up to 5 kg Control via hand controller with display and numeric keys Holder for Vixen-style dovetail plates 1-, 2- and 3-star alignment for initialisation Access to over 100,000 stored celestial objects Synchronisation and RA/DEC backlash compensation for greater accuracy 8 slew speeds as well as sidereal, solar and lunar rates Low-noise belt drive with worm gear Polar finder tunnel for rough alignment with the celestial north pole Polar finder scope for precise polar alignment available separately (Art.
