Product information "LUNT LS40THa/B500 H-alpha solar telescope"

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.

LUNT LS7-21ZE Zoom Eyepiece 7.2mm - 21.5mm

Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!FEATURESFocal length: 7.2mm - 21.5mm continuously adjustableBarrel size: 1.25 inch (31,7mm)Diameter: 47mmHeight: 82mmWeight: 170gEye relief: 15mmLenses / Groups: 7 lenses / 4 GroupsField of view: 53° at 7.2mm - 40° at 21.5mmSCOPE OF DELIVERYLUNT Zoom Eyepiece 7.2mm - 21.5mm

BRESSER Twilight I telescope mount with tripod

The Twilight I is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR102 + AR127s or ED102mm + ED127, and of course, the ED80mm. Lightweight, fast Newtonians will also match up nicely with the BRESSER Twilight I mount. As long as your telescope does not exceed 18 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The Twilight I alt-azimuth mount head is made of powder-coated aluminum and there are worm gears on both axes. The adjustable angle head can be tilted forward or back at a 45° angle to allow more clearance for your telescope so you can point it straight up for viewing at the zenith. The Allen hex wrench for doing the mount head adjustment can be safely stored at the integrated magnetic holder. Slow-motion control cables are attached on the vertical and horizontal axes, and are easy to turn during the night, even with gloves on, due to the over-sized knurled knobs that are attached to the end of each cable. They can be attached to either side of each axis to accommodate right or left-handed users, or different types of telescopes (e.g. refractors vs. Newtonian reflectors) for ease of adjustment. The stainless steel tripod that comes standard with the Twilight I mount has adjustable legs and a wide foot print of 42 inches, which makes the tripod more stable. A spreader bar locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. SCOPE OF DELIVERYTwilight I Telescope MountStainless Steel Field tripod

LUNT Heating Module for Blocking-Filter

At very cold temperatures, blocking filters may no longer work accurately central in the H-alpha wavelength, which means that the details on the sun become less visible. With this Heating-Module you can counteract this effect and observe the sun in the H-Alpha line optimally even at cold temperatures.The Heating-Module is for use with blocking filters in 90° star-diagonal housing from Lunt Solar Systems. It cannot be used at blocking filters in straight extension tube.The Heating-Module has an internal battery which allows for about 1 to 1.5 hours of operation. The battery can be recharged with the supplied USB cable.FEATURESAllows optimal observations in the H-alpha line even at very cold temperatures with blocking filters from Lunt Solar SystemsOperating time about 1 to 1.5 hoursInternal battery can be charged via USB cableCan also be used as a portable charger to power small electronic devicesInput (IN): 5V 2AOutput (OUT): 5V 2ACapacity: 5000mAhSCOPE OF DELIVERYLSBHEATER Heating-Module for Blocking-FiltersMounting screwsHexagon wrenchUSB cableInstruction manual(Blocking-filter not included!)

LUNT LS40FHa H-alpha double-stack filter for LS40THa

Double-stack filter for LS40THa telescopes. The bandwidth of H-alpha systems can be reduced by so-called "double-stacking". A smaller bandwidth provides much more contrast at the solar surface, thereby many more details will become visible. Double-stacking with a bandwidth of only <0.55 Angstrom is also possible at the LS40THa telescopes. Therefore Lunt Solar Systems has especially designed this LS40FHa double-stack filter in compact housing. FEATURES Aperture: 40 mm Bandwidth: <0.55 Angstrom Tuning: mechanical tilt-tuning Housing diameter: 70mm Length: 60mm Weight: 0,3kg only usable together with a LS40THa telescope!
