EXPLORE SCIENTIFIC 1.25" H-Beta Nebula Filter

One of the most important obstacles for the exploration of the night sky is the brightening of the night sky by artificial lights, such as streetlights. The night sky is not really dark in the vicinity of towns or cities, which reduces the visibility of objects bejond the solar systems enourmously. Depending on the type of the celestial object it is possible to increase the contrast dramatically by blocking the annoying artifical light. The Explore Scientific H-beta filter uses a characteristic property of the so called emmission nebulae. Those objekcts glow in special colors, the so called emmission lines. Those emmission lines are linked to chemical elements - in this case hydrogen. The Explore Scientific H-beta nebula filter blocks all other colors (and thereby nearly all of the artificial light) and only the emmission line of the hydrogen can pass the filter. The result is astonoishing: suddenly nebulae are visible at locations that were completely empty without filters. In suburbian skies for example the horsehead nebula is almost not visible with a 300mm telescope. By using this filter you can see the nebula and its structures without problems. A must for every visual observer. The Explore Scientific nebula filters come with a individual test certificate - your guarantee to receive a premium filter.

High resolution deep sky camera with large SONY EXMOR IMX-571 APS-C CMOS sensor and active cooling. This camera's extreme sensitivity is achieved through SONYs backside illumination technology. This camera should appeal to both advanced users and those looking to move up from DSLRs for more serious deep sky imaging.Enter the world of astrophotography now. With the new EXPLORE SCIENTIFIC Deep Sky Astro camera you get a modern complete package for straightforward shooting of astro photos and videos. Finally, an easy-to-use camera for capturing galaxies, star clusters, the moon and even planets with high resolution and low sensor noise. Thanks to the fast USB 3.0 computer interface, all image data is transferred within a few seconds. Long waiting times for images are now history. Simply connect the camera to your telescope using the T2 female thread (M42, 0.75 mm) or the supplied 2" (50.8 mm) plug-in adapter and after installing the drivers and the included EXPLORE Capture recording and editing software, you are ready to take the first real astro photos with a highly specialized camera for your application.  The EXPLORE Capture Pro software included in this package not only offers the basic functions required for image and video capture, but also many helpful special functions for image post-processing and camera setup. Functions such as live image display, exposure settings, white balance, dark image subtraction, stacking, timelapse recording and much more can be configured individually. This very sophisticated software makes your entry into astrophotography really easy. With the automatic settings you can produce absolutely presentable results without any previous knowledge. As soon as you feel confident, simply switch off the automatic settings and gradually explore the software's more individual professional settings. The new EXPLORE SCIENTIFIC Deep Sky camera has a highly sensitive and very low-noise SONY EXMOR IMX-571 APS-C CMOS Sensor, which can be cooled down to 40 °C below ambient temperature by the two-stage thermoelectric cooling. In contrast to normal DSLR cameras, this guarantees much lower noise and fewer hot pixels in your shots. The images are not only much sharper and more brilliant, but also contain more usable image information. Through the carefully automatically-controlled setting of the desired camera temperature, the it's easy to create of dark frames which can be re-used under similar shooting conditions - speeding up your processing considerably. The large-format CMOS sensor with 28.3 mm diagonal also allows large image fields and simplifies the adjustment and centering of objects considerably. The secret to the high light sensitivity of this camera is SONY's new back illuminated EXMOR CMOS sensor. It increases the quantum efficiency to up to 80 % at 533 nm, which leads to an extremely high sensitivity and subsequently particularly bright and high-contrast photos.The camera has a built-in USB hub with 2 x USB 2.0 ports at the rear. Connect your additional autoguider camera or motor focus etc. via a short USB cable and reduce the risk of cable tangles and cable breaks. Separate cable connections between your accessories and your computer are no longer necessary. A sturdy hard case for the camera plus accessories is also included. IMPORTANT NOTES: Don't get confused by the megapixel data and the contrary price structure. In the field of astronomy, the key criterion is not the sensor resolution but the maximum light sensitivity. The main goal is to capture as much light as possible in a short time.DOWNLOAD latest camera software and drivers see download folder "Manuals" or here: https://www.touptek-astro.com/downloads Sample photos made by Lóránd Fényes in Hungary: https://fenyeslorand.hu/m31/https://fenyeslorand.hu/ic349_merope_nebula/https://fenyeslorand.hu/asztrofotok/Field of view for different focal lengths in arc minutes and degrees: 400 mm - 201´ x 135´  (3.4 x 2.3 degrees)500 mm - 161´ x 108´  (2.7 x 1.8 degrees)600 mm - 134´ x 90´  (2.2 x 1.5 degrees)700 mm - 115´ x 77´  (1.9 x 1.3 degrees)800 mm - 100´ x 67´  (1.7 x 1.1 degrees)900 mm -  89´ x 60´  (1.5 x 1.0 degrees)1000 mm - 80´ x 54´  (1.3 x 0.9 degrees)1250 mm - 64´ x 43´  (1.1 x 0.7 degrees)1500 mm - 53´ x 36´  (0.9 x 0.6 degrees)1750 mm - 46´ x 31´  (0.8 x 0.5 degrees)2000 mm - 40´ x 27´  (0.7 x 0.45 degrees)FEATURESCamera type: ASTRO Colour Camera 26.0MP ATR3CMOS16000KPA Data output: single pictures and video Image Sensor: SONY EXMOR IMX-571 CMOS Colour Sensor Adjustable resolution: 6224x4168 / 3104x2084 / 2064x1386 Adjustable binning: 1x1 / 2x2 / 3x3 Frame rate per second (FBS): 6.8 / 28 / 63 Physical sensor size in pixels: 6224 x 4168diaginal: 28.3 mmMegapixel: 26 MP Sensor size: 23.48 x 15.67 mm (APS-C format)Pixel size: 3.76 µm x 3.76 µm Bit depth: 8 Bit / 16 BitBackfocus: 17.5 mm  Shutter Type: rolling shutterInternal camera memory: 512MB DDR 3 RAMThermoelectric cooling with fan: yes, up to 40°C below ambient temperature Adjustable exposure times: 150µs to 60min Operating temperature: -10 to +50°C (30-80% RLH) Cable length USB 3.0: 150cm DC cable length power supply: 200cm CNC machined aluminium housing Camera diameter: 80mm; length: 102mm Camera weight: 0.53 kg Camera connection diameter: 2.0 inch ( 50.8mm) Camera connection thread: T2 (M42x0,75mm) Filter thread: Yes, 2.0 inch in receptacle Camera connection to PC: USB 3.0 Built-in USB hub with 2 x USB 2.0 ports Power supply: Power supply 12 Volt 3,0 Ampere included Software: EXPLORE Capture included Camera driver and ASCOM driver includedOperating system: WINDOWS 10 + 11 PC requirements: CPU Intel Core2 2.8Ghz or higher / 2 GB Ram / USB 3.0 WHAT'S INCLUDEDDeep Sky Astro Camera 26.0MP Telescope adapter T2 thread to 2.0" (50,8mm) USB 3.0 connection cable 150cm Power supply 230V/12V 3.0A Dust cap Software CD Hard case Instruction manual

The NEXCOPE NE620T microscope is designed for a wide range of applications. It features a very high contrast, which ensures an outstanding image quality and resolution. This makes it ideal for demanding and professional applications. LENSES The panchromatic lenses ensure a flat field of view. The 100x lens is resilient to contact and is designed for a water immersion (NA: 1.10). The 40x lens has a very high working distance of 1.5 mm, which prevents contact with immersion fluids. The nosepiece has five positions and is equipped with four lenses (4x, 10x, 40x, 100xW). These feature an M25 thread and a parfocal length of 60 mm. EYEPIECES The eyepieces have a 22 mm field of view. This produces a wide-angle image. The high eyepiece head is ideal for spectacle wearers. A rubber edge provides protection upon eye contact. A dioptre compensation of -5 to +5 can be set individually for each eyepiece. The interpupillary distance can be adjusted between 48 mm and 75 mm. ILLUMINATION The condensor with an iris diaphragm is adjustable and provides Köhler illumination together with the light source, which is also equipped with an iris diaphragm. The powerful 3 W LED has an adjustable brightness and provides the best possible illumination. The brightness can be adjusted individually for each lens. When a lens is changed, the NEXCOPE NE620T automatically adjusts the previous brightness settings. The display shows the currently selected lens and the current brightness. MECHANICS The XY stage is moved via a combination of a toothed rack and tooth belt drive. This enables exact positioning for high magnifications. In addition to the coarse focus, the fine focus helps to render a very sharp image of the object. A full turn of the fine focus moves the table up/down by 0.2 mm. The fine focus can be adjusted with one finger on the right-hand side. The table height limit helps to protect the specimens. The friction of the coarse focus can also be adjusted. CAMERA CONNECTION The NEXCOPE NE620T is specially designed for use with c-mount cameras. You can choose from two different adapters, depending on the sensor size: 0.5x c-mount adapter1x c-mount adapter As the adapter can be adjusted, the camera image can be matched parfocally to the eyepieces. ACCESSORIES (available separately) Dark field Phase contrast Polarisation or fluorescence make the NEXCOPE NE620T microscope suitable for universal use.
