Herschel-wedge / Solar-wedge for superior White-Light solar observing and imaging. For refractor-telescopes up to 150mm aperture, and with 2'' focuser. Complete system with installed ND3.0 filter.Herschel-Wedges will be used to observe the sun in White-Light. Around 95 % of the sun light will be suppressed by the Herschel Wedge. The remaining sun light will be dimmed by a fix installed ND3.0 grey filter. Lunt Solar Systems Herschel-wedges are installed in a fully closed housing with integrated heat trap. There is no stray light escaping, therefore it is very safe.The difference between Herschel-wedges and normal front mounted filters is, that the filtering takes place just before the eyepiece or camera. This will provide a better contrast and sharpness of the solar image.Furthermore, there is more safety at a Herschel-wedge than at a front mounted filter. A Herschel-wedge can not rip or become holes like a foil. And also it can not drop down from the telescope objective accidentally.Only for use with refractor telescopes up to 150mm aperture:Because the full energy and heat of the sun will be inside the telescope, we advise to use only refractors with a Herschel-wedge. The refractor must not have corrector lenses at the back. Optical elements like corrector lenses, or secondary mirrors of reflector telescopes, become very hot by the concentrated solar energy and could be damaged.Tuning the brightness:Because the Herschel-wedge produce polarized light, you can use a normal polarizing filter at the eyepiece or camera-adapter. By turning the polarizing filter the brightness will be reduced.Polarizing filter not included. We recommend the BRESSER 2'' polarizing filter 4946465.FEATURESFor refractor-telescopes up to 150mm apertureConnection to telescope: 2''Connection to eyepiece: 2''90° housing like star-diagonalEspecially high-quality optical surfaces for very good contrastFully closed housing with integrated heat trapNo stray light escaping - therefore it is very safeThe needed ND3.0 filter is fix installedSCOPE OF DELIVERYHerschel-wedge for 2'' focuserIntegrated ND3.0 filterHardcaseInstruction manual
The zoom stereo microscope BRESSER Advance ICD is suitable for a wide variety of objects. Because of the Greenough design with two tilted objectives, you can view the sample in 3D. The three-dimensional view is also very helpful when working under the microscope, e.g. when soldering, dissecting or preparing a sample.The precise zoom enables you to view your sample in a wide range of magnifications from 1x to 4x (zoom ratio 4.0). When zooming, only slight refocussing is necessary. To do this, the Advance ICD microscope is equipped with a very precise, coaxial coarse and fine focus. The fine focus is especially helpful when using high magnifications or for imaging. When doing focus stacking with our MikroCam cameras (optional) the fine focus is also a big help.The interpupillary distance of the eyepiece pair is adjustable. Both eyepiece holders are equipped with diopter adjustment, which allows users with bad eyesight to compensate up to 8 dpt. difference between left and right eye. The 10x wide field eyepieces have field number (FN) 22 and are equipped with soft rubber eyecups. The microscope head can be moved on the long rod of the stand, which allows you to observe big samples up to a size of 22 cm.The angle of the bright LED reflected light illumination can be adjusted as necessary. The extra bright and even LED transmitted light provides a flat background when viewing transparent samples. The switch allows you to select reflected light, transmitted light or a combination of both to match your requirements. Brightness is adjustable with the dimmer. The bright light does not heat up, which allows you to observe also living specimens over a longer period of time. The long lasting LED is powered by a 5V AC adapter (EU/UK). The power cable comes with a USB plug.Fully equipped, the Advance ICD covers an exceptionally wide range of magnifications and is therefore suitable for a variety of tasks. Besides the included 2x lens there is also a selection of other auxiliary objectives available. With these, you are able to adjust magnification, working distance and depth of focus according to your needs.Magnifications in basic setting (no optional accessories):10x eyepieces: 10x – 40x10x eyepieces plus 2x auxiliary lens: 20x – 80x20x eyepieces: 20x – 80x20x eyepieces plus 2x auxiliary lens: 80x – 160x(other magnifications are possible when using other auxiliary lenses and/or eyepieces)The third tube is designed to permanently attach a camera. The image of the left eyepiece is diverted to the camera port with a lever/switch. We supply a selection of camera adapters for DSLR, mirrorless cameras and c-mount microscope cameras. This enables you to attach virtually any camera body as long as you have a model with interchangeable lens.APPLICATION RANGEQuality control in industryMaterials scienceLaboratoryBotany, gardening, farmingHydrology, aquaculture, fishkeepingInsects, Entomology, pest controlPlant physiology, raw food materials, medicinal herbsSchools, teachingFEATURESTrinocular head with 2 eyepieces and camera port with switchCompatible with BRESSER MikroCam cameras and others1x-4x stereo-zoom head2x auxiliary lensDiopter adjustment on both eyepiece holdersAdjustable interpupillary distance (52 – 72 mm)Bright LED light (reflected / transmitted)2 different object plates for best contrastView samples of up to 22 cm heightAC adapter Euro/UK (5V / 1000 mA) with USBHeavy build with metal standIncludes 2 pairs of widefield eyepiecesSCOPE OF DELIVERYMicroscope2 pairs of eyepieces (WF 10x / WF 20x)2x auxiliar lens (1 pcs)1 pair of rubber eyecupsObject plate 94 mm (black / white)Glass object plate 94 mm (matte)AC adapter Euro/UK (5V / 1000 mA)Dust coverPrinted manual
The BRESSER Science ETD 101 is a high-quality stereo microscope with transmitted light function, too. It can be used for observation studies in medicine and health, in farming and forestry, in public security departments, schools and scientific research institutes as well as for inspection, assembling and repair of tiny parts in electronics and precision machine industries. This broad spectrum is due to the comprehensive possibilities of the BRESSER Science ETD 101.
The broad furnished base with object stage and the extensive range of adjustable height allow the observation also of larger objects. The instrument has two illuminations (with 10 W halogen lamp each), which can be dimmed separately and can be used in three illumination modes: Transmitted light, reflected light and mixed light illumination. The incident angle of the reflected light illumination can be varied and fixed in a particularly user-friendly way. A pair of changeable wide field eyepieces (WF10x) and a stereo zoom objective (0,7x-4,5x) allow for the magnification range of 7x to 45x. The upright and true sided images are bright, true colored, rich in details and contrast. Naturally, the individual eye relief and the diopter adjustment can be set. The 360° turnable binocular head bears 45° inclined ocular tubes.

Enter the world of astrophotography now - with the new EXPLORE SCIENTIFIC 4K DEEP SKY ASTRO Camera including ST4 autoguider function.
This is truly new: Equipped with the new high-sensitive SONY IMX585 Exmor CMOS colour sensor, this astronomy camera delivers amazing image results with extremely short exposure times even with basic telescope equipment. In addition, this ultra-modern camera can also be used as an autoguider, e.g. to actively track the main imaging device with an SLR or CCD astro camera. An all-round camera that delivers super-sharp and high-resolution planetary images. The high 4K resolution of 3840x2160 pixels guarantees the best possible image result.
Sensor
The secret to the high light sensitivity is SONY's new back illuminated Exmor CMOS sensor.
It increases the quantum efficiency to up to 77 % at 533 nm, which
leads to an extremely high light sensitivity and thus particularly
bright and high-contrast photos. In addition, the particularly low noise level of this new CMOS sensor generation by SONY ensures exceptionally high brilliance and no active cooling is required.
Nevertheless, this astro camera has an elaborate internal structure
made of aluminium for ideal heat radiation and a fan that can be switched
on via software. When used with suitable telescopes, the high native
pixel resolution of 3840x2160 enables very nice overview images of the moon, but also detailed planetary images.
Solar Imaging
This camera is also recommended for solar astro-photography. Especially
the Lunt LS40 THa solar telescopes (item No. 0551145/0551146/0551147), with their short focal length, allow in combination with this planetary camera with its large sensor great overview images of the sun.
Important Note: When observing and taking photos of the sun,
always use a suitable protective solar filter or a special solar
telescope. Otherwise there is a risk of immediate blindness and damage
to the camera.
Software
The included Explore Capture professional software offers not only the necessary basic functions for image and video capture, but also many helpful special functions for image post-processing and for setting up the guider. Functions
such as live image display, exposure settings, white balance, dark
image capture, stacking, timelapse recording and much more can be
configured individually. Especially the very sophisticated software makes it really easy for you to get started in astrophotography. With the automatic settings you can produce absolutely presentable results without a lot of prior knowledge. And when you are ready, simply switch off the automatic settings and gradually venture into the individual professional settings.
Automatic tracking control
Connect the camera directly to the ST4 port of your telescope mount and you have a fully automatic tracking control. Thus, long exposures of several minutes are possible without
the stars producing unwanted star traces due to the always existing
periodic error of the telescope mount gears. A corresponding ST-4
connection cable is even included in the camera's scope of delivery. Because of the high
light sensitivity of the camera, you will always find a suitable guide
star even with very short exposure times. Simple automatic tracking at its best.
Connection
For the connection to telescopes, guiding scopes or off-axis guiders
the camera has a 1.25'' socket with 1.25'' filter thread (M28.5x0.6) and
a large T2 connection thread (M42x0.75) directly on the housing.
IMPORTANT NOTES:
This is not a stand-alone guider camera. You always need a Windows 10 or 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).
