LUNT LS50FHa/B1200d2 H-alpha solar filter

50mm H-alpha solar filter system with B600 blocking filter, for front mounting at telescopes with 2" focuser, and up to 540mm focal length.The LS50FHa H-alpha Etalon filter system with 50mm aperture (no central obstruction) for use on any refractor and many other telescopes. Because the LS50FHa has an estimated bandwidth of <0.75 Angstrom it is capable to providing high contrast views of both solar surface and edge detail (prominences).The system includes the B600 blocking filter, which is usable for telescopes up to 540mm focal length. Larger blocking filters suitable for longer focal length are also optional available. The blocking filter is installed in a 90° star diagonal for 2" focuser. This diagonal is equipped with a reception for 1.25" eyepieces and a T2 camera connection.Adding an additional available double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom.FEATURESAperture: 50 mmNo central obstructionBandwidth: <0.75 AngstromTuning: tiltable EtalonHousing diameter: 95 mmLength: 73 mmWeight: 0.7 kgFront thread: M90x1 female threadRear thread: M90x1 male threadBlocking filter: B600 in diagonal for 2" focuserMaximum focal length of telescope: 540 mmSCOPE OF DELIVERYLS50FHa solar filterB600 Blocking Filter (for 2" focuser) in star-diagonalTransport caseInstruction manual

Adapter plate for mounting a LUNT LS50FHa or LS60FHa front-filter at a telescope with 161mm to 180mm front outer diameter.With this adapter you can mount a LS50FHa or LS60FHa at your existing astronomical telescope with 161mm to 180mm outer diameter, in order to use this telescope for solar observing in H-alpha. The adapter is plugged onto the front of your telescope, and the filter can be screwed onto the adapter.PLEASE NOTE:This article no. 0557415 gives only the price for a complete range of different adapter-plates of 161mm to 180mm diameter.

50mm H-alpha double-stack solar filter, for all LS50FHa filter-systems and LS60THa/LS60MT telescopes.This double-stack Etalon is compatible to all Lunt Solar Systems LS50FHa filter-systems and LS60THa / LS60MT telescopes. Adding this additional double-stack Etalon system will reduce the bandwidth to ~<0.55 Angstrom (dependent upon used telescope). So you will have much more contrast and more details on the sun will be visible.Without blocking filter! Only for use as double-stack filter, or together with a additional available blocking filter. If the filter is used only single stacked together with a optional blocking filter, then the bandwidth is <0.75 Angstrom.FEATURESAperture: 50 mmNo central obstructionBandwidth double stacked: <0,55 AngstromTuning: tiltable EtalonHousing diameter: 95 mmLength: 73 mmWeight: 0.7 kgFront thread: M90x1 female threadRear thread: M90x1 male threadSCOPE OF DELIVERYLS50FHa solar filterTransport caseInstruction 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. FEATURES EXOS-2 MOUNT Stable parallactic mount with fine drive in both axes Ball bearings in both axes for more precise movements Sturdy height-adjustable stainless steel tripod (Min. 69 cm / Max. 109.5 cm) Load capacity of up to 13 kg Spirit level for easy horizontal alignment Polar height scale for setting the latitude Polar scope with optional lighting (item no. 4964212) Tripod weight: 4.7 kg Mount weight: 5.6 kg (without counterweight) Total weight including counterweight: 14.8 kg Batteries: not included FEATURES GOTO SYSTEM Belt drive for a more precise, quieter tracking Stepper motors with high resolution (0.36´/microstep) Hand control box for direct control of the mount Virtual hand control box for smartphones and tablets PC control – ASCOM compatible USB ports for cameras, motors, filter wheels etc. SCOPE OF DELIVERY BRESSER EXOS-2 Mount Polar finder scope with optional illumination Stainless steel field tripod with accessory tray 1x 4.5-kg counterweight 2 stepper motors for the axes (RA and DEC) Raspberry Pi control unitBasic handbox 230V / 12V / 3 A power adapterConnection cableManual for download
