BRESSER JUNIOR 24 Permanent Microscope Starter Kit (Refurbished)

The NATIONAL GEOGRAPHIC VA colour RC weather station shows you all important weather information at a glance. On the clearly arranged colour display you will not only find such information as indoor and outdoor temperature and humidity but also the exact DCF time which is received via radio transmission . For the UK the received EU DCF time signal can be offset by -1h automatically and the British time can automatically be seen wherever the time signal is received in the UK (southern England and parts of Wales). The current weekday and date are also displayed. The weather station also features a weather forecast for the upcoming 12-24h, air pressure display, alarm with snooze function and of course backlighting round out this multi function station. FEATURES BASE STATION LCD colour display Indoor temperature (°C/°F) and humidity from the integrated thermo-/hygrometer sensor  Outdoor temperature (°C/°F) and humidity from the included Sensor Barometer display in hPa Display of time, date and weekday Time via DCF radio signal Weather Forecast Alarm function with two adjustable wake-up times and snooze function Maximum connectable sensors: 3 (1x included!) Hanging device and fold-out stand Power supply: Mains Adapter (incl.)FEATURES SENSOR Measurement of outdoor temperature (°C/°F) and humidity Hanging device and stand on the back 3 channels adjustable range of 30 m Power supply: 2x AAA batteries (not included) SCOPE OF DELIVERY Weather station 1x outdoor sensor Instruction manual

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).DOWNLOAD PHD2-Guiding: https://openphdguiding.org/DOWNLOAD GuideDog: http://barkosoftware.com/GuideDog/index.htmlDOWNLOAD latest camera software and drivers: https://www.touptek-astro.com/downloadsDownload INDI Driver: https://github.com/indilib/indi-3rdparty/tree/master/indi-toupbaseSPECIFICATIONSCamera type: BRESSER / Touptek GPCMOS02000KPA colorSensor: SONY IMX290 CMOS color, backlitImage and video size: Full HD 1936 x 1096 pixels (video 15 FPS)Native sensor size in pixels: 1936 x 1096Exposure times: 66µs to 16minBinning: YES, 2x2Megapixel: 2.1 MPSensor size in mm: 5.6 x 3.1Pixel size: 2.9 µm x 2.9 µmBit depth: 8/12 switchableST-4 Compatible Autoguider: YESCNC milled housing made of aluminumProtective strap on the camera housingCamera tube diameter: 1.25 "(31.7 mm)Camera connection thread: C-mount + 1.25 "filter threadComputer interface: USB 2.0C-mount extension tube with 1.25 inch filter thread includedNo IR cut filter installedCompatible systems: WINDOWS 10 + 11, Linux, StellaVitaASCOM driver includedField of view for different focal lengths in mm (given in arc minutes):400mm - 48.2 'x 27.3'500 mm - 38.6 'x 21.8'600 mm - 32.1 'x 18.2'700 mm - 27.5 'x 15.6'800 mm - 24.1 'x 13.6'900 mm - 21.4 'x 12.1'1000 mm - 19.3 'x 10.9'1250 mm - 15.4 'x 8.7'1500 mm - 12.9 'x 7.3'1750 mm - 11.0 'x 6.2'2000 mm - 9.6 'x 5.5'SCOPE OF DELIEVERYFull HD cameraC-mount adapterUSB 2.0 PC connection cable with a length of 200cmInterface cable for ST-4 autoguider port with 150cm lengthDust cap for camera tubeSoftware download

It is a complete system for the exploration of the wonders of the universe, consisting of telescope, mount, tripod and all accessories needed. With an aperture of 70 mm it reveils already many details of celestial objects. The mount can not only swing the telescope left / right and up / down, it can also be used in a so-called equatorial mode, as scientists do in their observatories (see further under Special features). An additional finder scope mounted on the telescope is useful for locating celestial objects. With the erecting lens many exciting things in the environment can also be seen during daytime. With the height-adjustable tripod, the telescope can each be brought to an optimal height for large or small observers. The supplied diagonal mirror ensures a comfortable viewing. At night the moon and planets may like Saturn and Jupiter can be explored. But thanks to the 70 mm wide aperture of the telescope also many celestial objects outside our solar system are within the reach of this telescope. Star clusters many light years away and nebula impress young and old stargazers. SPECIAL FEATURESMounting with wedge: At first glance, the NG mount of the refractor telescope90/700 NG is a very ordinary azimuth mount: an axis for left / right and one for up / down, as we know it from normal camera tripods. This mode makes sense especially with observations during the day. With the built-in wedge it can be tilted, so the whole mount can be converted to an equatorial mount for astronomy with a single operation. For use of the equatorial mount an axis is aligned with the North Star. When tracking a celestial object only a single axis needs to be moved, which clearly is a relief compared to tracking an object on the night sky with mounts that only have left / right and up / down axis. FEATURESideal beginner's setsuitable for lunar, planetary and nature observationsmount can be used in two ways: alt-azimuth and equatorialSCOPE OF DELIVERYrefractor telescope 70/900three eyepieces: 4 mm (225x), 12 mm (75x) and 20 mm (45x)heigth-adjustable aluminium tripod with accessory tray1.5x errecting lens for a laterally correct and upright imageNG mountfinderscope 6 x 25astronomy software for PC90° diagonal mirror
