The three-lens design of the EXPLORE SCIENTIFIC ED-Apochromats provides everything an amateur astronomer desires - at a reasonable price. The construction with Hoya FCD-1 ED glass has two air spaces and provides a level of correction so superior to the two-lens constructions, that are common in this price class, that you will see the difference immediately. This excellent optical performance teams up with a high precision mechanics - the result is a telescope on a level that is setting a new standard in it´s price class. Astrophotographers will love this telescope - a optional field flattner is available and makes the telescope perfect even for cameras with a large chip format.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))FEATURESthree lens air-spaced ED-apochromatHoya FCD01-ED glasspolystrehl of above 0.9weight: 2,6kgbackfocus: 165mm above 2" adaptorSCOPE OF DELIVERYOptics with dovetail plate and finder slot 2" Star Diagonal 99% reflectivityDust caps for front-lens and focuser

With the new BRESSER PushTo AR-80/400 Smart Telescope, admiring the beauty of the night sky has never been easier. Thanks to the modern app, navigating the firmament becomes a breeze – the ideal start for anyone eager to dive into the exciting world of astronomy! Smart all-rounder for astronomy beginners Moon, planets, star clusters, and brighter nebulae – with the BRESSER PushTo Navigation Smart App, you can enjoy the view of fascinating celestial bodies through the telescope in just a few seconds. How about taking snapshots of the moon? It’s easy with the included smartphone adapter. The sun's breathtaking sights aren't to be missed either; observe and photograph it safely with the provided solar filter through the PushTo AR-80/400. A true all-round telescope for both day and night! Get started immediately with the smart telescope The telescope is very easy to operate and can be started without much effort. The first steps only involve downloading the BRESSER PushTo Navigation Smart App and a brief initialization of the telescope. Then you will immediately see the current viewing direction via crosshairs on the star map displayed on the connected mobile device. This is made possible by the sensors integrated in the telescope and the Bluetooth connection to your mobile device. And thanks to the slip clutches built into both axes, you can easily move and adjust the optical instrument by hand. Clever celestial navigation with the smart telescope Once set up, simply select any object on the PushTo Navigation star map via touch, and navigation begins. The displayed direction arrows, which change in length and colour as you approach the object, guide you reliably to your destination. Meanwhile your telescope’s movements are mirrored on the star map in real time. Once you reach the destination, you can immediately marvel at the desired celestial body. Alternatively, you can choose an object from the extensive database. Or make it even easier and opt for one of the preset sky tours for spring, summer, autumn, and winter. And you can quickly enjoy observing your favourite objects over and over again – just save them! Impressive optics for compact and extensive objects The powerful refracting telescope with an aperture of 80 mm shows you many of the most popular celestial bodies particularly bright and contrast-rich. The moderate focal length of 400 mm also allows for beautiful broad views of large objects such as open star clusters and bright nebulae. Additionally, you will definitely be amazed when the moon craters and the Jupiter moons suddenly become visible through the smart telescope, and you perceive the famous ring of Saturn. Versatile celestial observation – with tripod or as a table device The included field tripod can be quickly adjusted to the appropriate height for comfortable use of the optical device. But even without a tripod, the smart telescope reliably shows you the wonders of the starry sky. That’s because the BRESSER PushTo AR-80/400 can be used as a super compact tabletop device. Ideal for quick observations at home or for your next trip to dark locations. Flexible power supply The telescope can be operated with 4 AA batteries or via a USB-C connection cable with a power bank or a power adapter (not included).

BRESSER Full HD Deep Sky Camera with autoguider: a great camera for different types of astrophotography and for autoguiding. Not only suitable for planets, but also for deep-sky objects such as galaxies, nebulae and star clusters. Dedicated ToupSky Astro Imaging software supports video preview, video recording, video processing, image capture and processing, dark field correction and raw data output. Easy to use, but with professional results. One of the main features of the new backlit SONY IMX290 CMOS sensor is its high light sensitivity, which makes it possible to detect deep-sky objects without active cooling. SONY has increased the quantum efficiency at 533 nm wavelength up to 77%, which is much better than other CMOS sensors have been able to achieve in the past. Connect this camera to a guidescope and attach the camera's built-in ST-4 port, directly to your telescope's equatorial mount guide port and autoguide - using many popular audioguiding programs (PHD, Guidedog and more). Autoguiding enables you to take accurate pictures with long exposure times of several minutes. Thanks to the extra light-sensitive camera, you now always have a suitable guide star to hand, even using short exposure times. An ST-4 protocol connection cable is also included. Simple automatic tracking at its best. You can use this camera with all guiding telescopes, or off-axis guiders that accept a 1.25 " tube, 1.25" filter thread (M28.5x0.6) or C-mount adapter thread (1 "x1 /32"). IMPORTANT NOTES: This is not a stand-alone guider camera. You always need a Windows 10/11 computer to take pictures and for autoguiding. The autoguider software is not included. You can use PHD2 Guiding, Guidedog, Metaguide, Guidemaster (freeware) or AstroArt, MaxIm DL (paid).
