LUNT LS40THa/B600 H-alpha solar telescope (Refurbished)

Solar observation in H-Alpha: prominences, filaments, flares ... the most spectacular way to see the Sun - easy and affordable with the LS40THa.Complete H-alpha solar telescope with 40mm aperture, <0.7 Angstrom bandwidth, B500 blocking-filter, and Helical focuser.The LS40THa/B500 is a complete telescope for observing the sun in H-alpha, with 40mm aperture (no central obstruction) and 400mm focal length. The H-alpha wavelength is the most impressive way to observe the sun, showing protuberances at the sun's edge, filaments and flares on the surface, and much more. An Etalon with mechanical tilt-tuning provides <0.7 Angstrom bandwidth.Fine adjustment is achieved with a 1.25 inch Helical focuser. Blocking-filter is the B500, this is good for visual observation of the sun. The star diagonal in which the blocking filter is installed, is equipped as standard for 1.25 inch eyepiece connection.The easy handling makes this telescope ideal for starting H-Alpha solar observation. Due to its compact dimensions it is also a good travel telescope for the experienced solar observers.The LS40THa telescopes are available with choice of B500, B600 or B1200 blocking filters. The larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes have only a very small back focus and therefore photography is difficult. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera item number 4959050.FEATURESAperture: 40mm (no central obstruction, 2-lens refractor)Focal length: 400mmBandwidth: <0.7 AngstromTuning: mechanical tilt-tuningBlocking filter: B500 with 1.25 inch connectionFocuser: Helical focuserDovetail bar at standard GP-level1/4-20 tapped base (standard thread for photo-tripods)Sol-Searcher includedWeight: 1.2kgLength: 41cmSCOPE OF DELIVERYLS40THa Solar TelescopeB500 blocking filter in star-diagonal housing1.25 inch Helical focuserDovetail bar (GP level)Sol-SearcherInstruction manual

Discover the possibilities and forge new paths with the Nebula EXOS-2 Goto Mount!Mount and TripodThe BRESSER EXOS-2 is a stable mount with a high load capacity and precise tracking for visual observations and astrophotography. Double radial groove ball bearings in both axes ensure precise, smooth motion, and the RA axis bearing has been optimized to reduce backlash. Additionally, the tripod is reinforced to further suppress vibrations. The BRESSER EXOS-2 can be loaded with up to 13 kg of optics for purely visual use depending on the length and purpose!Nebula: the powerful and flexible Goto systemWith the new Nebula Goto system, set off for new astronomical shores. This system offers several control options. You can operate the mount directly via its own Nebula control interface using your smartphone or tablet (iOS and Android supported). Alternatively, you can also use a planetarium software such as SkySafari. Manual control remains an option as well. For this, a hand box for minor corrections or simple control commands is included.Furthermore, with the BRESSER Nebula Goto Kit, you can connect your laptop or PC directly via WIFI or LAN cable (recommended for faster data transfer) to the Nebula control unit. This not only gives you full control over the mount but also allows you to connect various devices such as cameras, motor focus, filter wheels, etc. directly to the control unit via various USB ports. This eliminates the need to connect each device to your computer via cables. The pre-installed program KStars / EKOS lets you comfortably control all devices from your PC or laptop. Electronic polar alignment or guiding can also be easily achieved with the Goto Kit, provided you have a camera connected. You are also not limited to the software of the Nebula control unit. Thanks to the installed ASCOM Alpaca driver, you can use your own programs on your computer to control the mount - whether it's Stellarium or N.I.N.A. The two stepper motors with a belt drive ensure a smooth, direct drive of the two axes. It's only important to have a good balance.
