EXPLORE SCIENTIFIC 100° Ar Eyepiece 20mm (2")

These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil.Each 100° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus. This also maximizes the life of the internal coatings.To make sure, every 100° eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. All 100° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

Are you having trouble focusing your eyepiece or camera? Then use this BRESSER 25 mm extension sleeve to increase the distance between the 2.5 inch HEXAFOC eyepiece extension and the eyepiece or camera. The extension sleeve has an M68x0.75 mm internal and external thread and can therefore be screwed directly onto the HEXAFOC draw tube.SPECIFICATIONSIncreases the distance to the eyepiece/camera Suitable for 2.5 inch HEXAFOC Optical length: 25 mm Internal and external thread: M68x0,75 mmInside black matt coated Material: aluminium, black anodized SCOPE OF DELIVERYExtension sleeve 25 mm (1 piece)

The new BRESSER Nebula 6 EQ/AZ Wifi-Network Mount is a precise and quiet telescope mount – ideal for astrophotography. The controller box offers numerous central connection options for various accessories such as cameras, filter wheels, and motor focusers via USB (2.0/3.0), simplifying the setup of a professional astro-photography machine. BRESSER relies on innovation paired with quality Made in Italy for this top-class product. The long-standing experience of the manufacturer in mount construction guarantees a high-end device with first-class functionality and highest reliability. Additionally, the in-house development team for hardware and software in Italy ensures quick response times in technical support and the adaptation of new device drivers. True to the motto "Professionals at work!" The mount is controlled via pre-installed web app software, accessible via Wifi and an Ethernet cable connection. The philosophy behind the Nebula GoTo system is to provide the user with a control system independent of a normal PC, which can be remotely controlled in all its functions 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 is already equipped with all Linux-based applications necessary for performing all astrophotographic functions.The existing INDI environment allows the control of almost all devices (cameras, filter wheels, rotators, including observatory domes), necessary for conducting 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 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 aluminum. The simple and functional design is thanks to a renowned Italian mount manufacturer, who has designed and now also manufactures these fine BRESSER products 100%. So, look forward to a stable yet easily transportable mount, which despite its light weight of only 16 kg (including tripod) allows a high load capacity of up to 25 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 6 via WLAN directly to your smartphone or tablet and use the virtual hand control box. Of course, all adjustment parameters can also be adjusted 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, remote capability is crucial. Connect your laptop or PC either via WLAN or with an Ethernet cable (recommended for faster data transfer) directly to the Raspberry-Pi control unit of the mount. Then use the pre-installed software Kstars/EKOS 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 only. 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 simply as a counterweight to the main telescope. Set the Nebula 6 to azimuthal mode, remove the counterweight bar, and screw on an extension adapter with a suitable second telescope clamp directly to the mount.
