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 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.

BRESSER Twilight I telescope mount with tripod
£280.00*
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 LS40FHa H-alpha double-stack filter for LS40THa
£998.00*
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

For visual observation we recommend an additional zenith mirror. The straight extension tube, in which the blocking filter is installed, is equipped as standard with a 2" eyepiece holder and also with an adapter for 1.25". Focusing is done by the legendary Feather-Touch focuser from Starlight-Intruments with 10:1 reduction.FEATURESAperture: 230mm (no central obstruction)Focal length: 1610mmBandwidth: 2 internal Etalons with <0.5 AngstromsTuning: Air-pressure tuning systemElectronic pressure tuner controllerBlocking filter: B3400 with 2" and 1.25" connectionFocuser: Feather-Touch focuser from Starlight-Instruments with 10:1 reductionTwo tube ringsDovetail bar with Losmandy level for astronomical mountsWeight: 35kgLength: 165cmSCOPE OF DELIVERYLS230THa Double-Stack H-alpha solar telescope2x Pressure-TunerElectronic pressure tuner controllerB3400 blocking filter in straight extension tubeFeather-Touch focuserTube rings with dovetail bar (Losmandy level)Manual
LUNT LS50THa/B400PT H-alpha solar telescope
£1,698.00*
A very compact, complete telescope for observing the sun in H-alpha light.The LS50THa solar telescope offers 50 mm free aperture, 350 mm focal length, and provides a bandwidth of <0.75 Angstrom. The telescope is fitted as standard with the air-pressure tuning system "Pressure-Tuner", the Etalon is safely installed inside the telescope. Prominences and surface detail can quickly be viewed spontaneously. This very portable system is an ideal travel companion for wherever you go.A B400 blocking filter is installed inside the star diagonal. The B400 is good for visual observing. Focusing is achieved by a non-roting Helical focuser.Please note that there is only a small back-focus at this telescope, therefore solar-imaging is very difficult. The LS50THa is designed for visual solar observing. We recommend for imaging the 60mm telescopes of the LS60MT series.Also double-stacking with a bandwidth of only <0.5 Angstrom is possible by using the additional available LS50C filter (0550210). This filter threads directly onto the LS50THa telescope. Double-stacking will provide much more contrast, and more details on the sun will become visible.FEATURESAperture: 50 mmFocal Length: 350 mmBandwidth: <0.75 AngstromTuning: air-pressure tuning system "Pressure-Tuner"Blocking Filter: B400non-rotating Helical focuserTube-ring with 1/4-20 tapped base (standard thread for photo-tripods)Length: 37cmWeight: 2.1kgSCOPE OF DELIVERYLS50THa H-alpha Solar TelescopeB400 Blocking Filter in star-diagonalPressure-TunerTube ring with 1/4-20 connection for mounting on photo-tripodsnon-rotating Helical focuserInstruction manual
