EXPLORE SCIENTIFIC TELRAD Projection Finder Scope with base
The TELRAD viewfinder is a projection finder that can be installed on any telescope and makes it child's play to align the telescope with the starry sky.The TELRAD viewfinder is a practical alternative to classic optical viewfinders and illuminated red dot viewfinders. You can see the complete starry sky without magnification, and not just a small section as with a normal optical viewfinder. Against this background of the starry sky, three red luminous concentric rings are projected, with apparent diameters of 4 degrees, 2° and 0.5° in the sky. Move the telescope so that the object you are looking for is in the inner ring, and the telescope points in the right direction. Because the object you are looking for is inside the ring, it will not be irradiated like a normal illuminated red dot finder.The base of the TELRAD viewfinder is self-adhesive and can be mounted on all telescopic tubes from about 10cm diameter. The length of the base is about 18cm. This base remains on the telescopic tube, the TELRAD viewfinder itself can be removed or attached at any time by means of the attached quick coupling. The TELRAD is powered by two normal AA batteries (not included).There are star atlases, like the "Deep Sky Travel Atlas" from Oculum-Verlag, and planetarium programs for the PC, like the program "Stellarium", where the three rings of the TELRAD are already drawn or can be displayed around the interesting celestial objects. This makes finding these celestial objects a real walk.FEATURESTELRAD projection finderIlluminated rings of 4 degrees, 2° and 0.5° in the skySee the complete starry sky without magnificationEasy installation and useCan be installed on nearly every telescopesBase with quick release coupling included Powered by two AA batteries (not included) Very long battery life because of LED technologySCOPE OF DELIVERYTELRAD viewfinder with projector and battery compartment TELRAD base with quick-release coupling for the viewfinder Adhesive tape for attachment to telescope

EXPLORE SCIENTIFIC 1.25" S-II Nebula Filter 12nm
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 beyond the solar system enormously. Depending on the type of celestial object, it is possible to increase the contrast dramatically by blocking the interfering artificial light. The EXPLORE SCIENTIFIC S-II filter uses the property of the so-called emission nebulae. These objects glow in certain colors, the so-called emission lines. The emission lines are associated with certain chemical elements - in this case ionized sulfur. The EXPLORE SCIENTIFIC S-II nebula filter blocks all other colors (and thus almost all artificial light) and lets only the emission lines of ionized sulfur at 672 nm through. The effect is amazing: suddenly, nebulae become visible in places that appear completely empty without the filter. In slightly brightened skies many planetary nebulae, emission nebulae and supernova remnants can be seen without any difficulties when using this filter. A must for every visual observer and for astrophotography. EXPLORE SCIENTIFIC nebula filters come with an individual test report - so you can be sure to get high quality filters. FEATURES Simplifies the observation of planetary nebulae, emission nebulae and supernova remnants Blocks almost all artificial light Lets only the emission lines of ionized sulfur at 672 nm pass Transmission bandwidth: 12 nm Allows for more contrast in faint deep sky objects Ideal for use near cities, in slightly brightened skies Individual test certificate included to guarantee you receive a premium filter SCOPE OF DELIVERY 1x 1.25'' S-II nebula filter

BRESSER USB Motor Focuser for HEX and R&P
The BRESSER USB Motor Focuser for HEX and R&P lets you achieve pinpoint focus on your telescope remotely and without any physical contact – whether you're enjoying a casual visual session or pushing the limits of astrophotography. The EAF works with hexagonal (HEX), rack-and-pinion (R&P) and most other standard focusers, connects in seconds via USB-C, and gives you the choice between manual control via the hand controller and fully automated focusing through your astro software of choice. Hands-off focusing via hand controller The included wired hand controller lets you dial in focus from a distance without laying a finger on the telescope. For astrophotography, this is a genuine game-changer: imaging sessions run uninterrupted and your focus stays locked in from first light to the end of the night. Visual observers will appreciate it just as much – precise focus adjustments on demand, no fumbling in the dark. Autofocus and broad software compatibility The EAF integrates smoothly with the most popular astro software packages. The ASCOM driver covers the vast majority of Windows-based applications, while full INDI and INDIGO support makes it equally at home on Mac and Linux. If your software includes an autofocus routine, the motor will handle everything automatically – a real asset for long, unattended imaging runs.Temperature sensor for sharp results all night long As the night progresses, temperature drops can cause the telescope tube and optics to contract slightly – enough to nudge your focus point off target. The included temperature sensor tracks these changes continuously and, paired with compatible software, compensates for any thermally induced focus shift on the fly. The result: consistently sharp images from dusk till dawn, with no manual intervention required.Please note: The temperature sensor and hand controller cannot be used at the same time. FEATURES Precise electronic motor focuser Plug and Play via USB-C Compatible with HEX, R&P and most standard focusers ASCOM, INDI and INDIGO driver support for maximum software compatibility Autofocus support via third-party software Manual focusing via hand controller Temperature sensor to compensate for thermally induced focus shift Robust aluminium housing SCOPE OF DELIVERY Electric motor focuser Mounting plates Wired hand controller Screws Washers Flexible couplings USB cable Temperature sensor Allen key Manual

BRESSER Photo mount with field tripod and wedge
Do you already own a photo camera and would like to create impressive pictures of the night sky with the help of the long exposure or even make time-lapse pictures with little effort ? The BRESSER photo mount is the ideal base. Not only for beginners in astrophotography, this mount is particularly well suited, but also the experts swear by a compact and easy-to-use mount to automatically compensate for the natural rotation of the earth. The built-in tracking motor rotates the saddle-mounted camera precisely against the earth's rotation and thus the stars remain punctiform even with long exposures. Which cameras are basically suitable for use with the BRESSER photo mount ? All cameras with ¼ inch (6.3mm) tripod connection thread and bulb length" B "for long exposure are suitable. The BRESSER photo mount is designed for a camera with lens of max. 2.5 kg total weight to carry and track. Large aperture, wide-angle lenses are ideal for the beginning, because the requirements for tracking accuracy accumulate with increasing focal length and exposure time. Thus, a shot with wide-angle lens can be exposed for up to several minutes and the stars remain punctiform without problems. For example, with a 200mm telephoto lens the polar alignment of the photo mount must be exactly right. But thanks to the optical pole finder, this is done quickly.  After setting up the light and compact photo mount, simply set the approximate latitude (pole height) to the scale and aim Polaris through the illuminated pole finder scope. Then mount the camera with the photo lens using the quick-release plate on the supplied ball head. With the ball head, the camera can be aligned and determined at any time on any section of the sky. As soon as the tracking motor is switched on, long-time exposure can be started immediately. This does not even take 5 minutes ...  The tracking is carried out by a precise stepper motor, which can also be moved via the hand box with 2- or 32-fold speed in forward and reverse. Thus, the sky section can be adjusted even more precisely. Low power consumption allows up to 50 hours of operation with just one battery charge.  The height-adjustable stainless steel tripod with polar wedge is an extremely stable base for the BRESSER photo mount. Thanks to the integrated circular level in the tripod head even the leveling of the photo mount is child's play. If you already own a sturdy photo tripod with a video tilt head you can use the photo mount's head directly with the 1/4 inch & 3/8 inch photo thread holes. The pole height (latitude) is then adjusted by the video tilt head. The photo-mount and the tripod with polar wedge are also available separately - Product No.: 4964111 and 4964112   FEATURESEquatorial Photo-MountAdjustable stainless steel field tripod with polar wedge and bubble levelAutomatic siderial tracking against the Earth rotation Handbox to control the tracking motors (2x/32x)Suitable for northern and southern henisphereOptical pole finder scope with illumination unit includedBallhead with quick release saddle plate and 1/4" Photo thread for Kamera mountingPhoto-Mount with 3/8" threaded bolt for ballhead mountingPhoto-Mount with 1/4" und 3/8" inner threads for tripod mountingHigh precision stepper motor with helical gear for accurate tracking Large screws and handles for easy usage at night  Battery operation or stabilized power adapter (optional acc.) Battery life: up to 50 hoursPower connector at handbox: 6 volts DC jack 5.5/2.5mm (positive pole at center pin)Weight Photo-Mont with ballhead: 1.4 kg Weight tripod with polar wedge: 3.5 kgLoad capacity of Photo-Mount: up to 2.5 kg Height of camera sattle plate max. 140 cmSCOPE OF DELIVERYFoto-Mount headTracking motor with HandboxUltra-stable stainless steel field tripod with bubble levelBallhead with quick release saddle plate Pole finder scope with illumination unitBattery compartment 6 volts with case (no D-batteries included)Manual
