EXPLORE SCIENTIFIC Hexafoc 2.5 adaptor for 3" 0.7x Corrector

The EXPLORE SCIENTIFIC 3" 0.7x Reducer/corrector, reduces a compatible telescope's focal length by a factor of 0.7x (for around f/8) and 0.8x (for around f/10) respectively. The reducer/corrector not only reduces the focal length but also flattens the field. Although originally developed for the Explore Scientific ED-APOs 127mm and 152mm, the reducer can be used with many systems - for example with the Explore Scientific ED-APOs 102mm and 165mm (please note, this will not work on the Explore Scientific 80mm ED Apo refractors though). With certain telescope focal lengths, a slight restriction of the correction at the edge of the image field can be expected when using full-frame sensors. This unit comes with 3" barrel adaptor for direct focuser thread M54x0.75 (the standard focuser thread of the Explore Scientific Essential series of ED Apos) and T2 camera adaptor. This reducer/corrector features a free aperture of 65mm, so that it can be used even with cameras that have a large sensor - if the telescope allows for this. Note: As previously mentioned, this Reducer/corrector comes with a screw on ring, which fits the standard focuser thread of the Explore Scientific Essential series of ED Apos. For telescopes which are equipped with the 2.5" HEX Focuser, the optional screw-on adapter part no: 0510366 is needed. Other telescopes, not in the Explore Scientific range, with standard 2" push-fit focusers will need the Explore Scientific 2" Adaptor for 3" Corrector - part no: 0510364 to get this reducer correctly fitted.

Highly corrected 102mm air-spaced triplet apochromat (with three lenses) and carbon fiber tube and a 2.5" high-precision HEXAFOC focuser.   Apochromats are the ultimate choice in small to medium sized telescopes: the combination of compactness, transportability, very high image contrast and sharpness together with the possibility to make excellent astrophotos cannot be bested. The advances in glass manufacturing during the last few years have made true apochromats available to more astronomy enthusiasts than ever before. The new Explore Scientific FCD-100 CF Hex represents another major improvement in this field - the overall correction (color and spherical) is setting new standards in this price class. The optical design shows a polystrehl value of 0,97 indicating a level of correction that is absolutely top of the line.This excellent apochromat is a very versatile telescope: the fast f-ratio makes short exposure times possible. The high contrast and sharpness of the image provide breathtaking views of large objects like the North america nebula or the Andromeda galaxy as well as tack sharp planetary images. The telescope is lightweight and compact - the dew shield slides down the tube to minimize size for transportation. Revolutionary glass and precision manufacturing created a telescope that offers observing joy on the highest level. This does not only qualify this telescope as the ideal travel scope, it is also the perfect choice for fast observations and for astrophotography. The excellent 2,5" HEXAFOC focuser with 10:1 reduction is perfect for this - the large inner diameter of 65mm prevents vignetting by the focuser when the telescope is used for astrophotography with large sensors. These very popular EXPLORE SCIENTIFIC Triplet ED APO Refractors we do offer in 3 different product lines:Essential Line: HOYA FCD-1 Glass lens, AL-Tube, 2.0" Rack&Pinion Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112084(AL), 0112106(AL), 0112132(AL)), 0112155(CF + 3"FT)) Professional Line: HOYA FCD-100 Glas lens, AL/CF-Tube, 2.5" HEXAFOC Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112086(AL), 0112108(AL), 0112109(CF), 0112134(AL), 0112135(CF))High-End Line: OHARA FPL-53 Glass lens, Carbon(CF) Tube, 3.0" Feather-Touch Focusser with 1:10, 2.0" Star Diagonal 99% Reflectivity (see Part No. 0112165(CF))SPECIFICATIONSAperture: 102mmFocal Length: 714mmFocal ratio: f/7.0Design: Apochromat with three lenses, two air spaces and FCD-100 glassWeigth: 3,3kg , lightweight due to carbon fiber tubeBackfocus: 150mm above 2" adaptorDesign: Apochromat with three lenses, two air spaces and FCD-100 glassSCOPE OF DELIVERYOptical tube with retractable dew-shield2.5" HEX focuser with 1:10 gear reduction  2" Star Diagonal 99% reflectivityTube rings with dovetail plate and handleExtension tubes for focusser (2pcs)Dust caps for front-lens and focuserUniversal finder slot

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.
