LUNT LS50C H-alpha double-stack filter for LS50THa

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

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

The Pulsar Observatory Dome provides a high quality, secure and practical housing for your telescope. Providing excellent weather protection for you and your telescope, it allows you to have your instrument ready for use at all times. Whether imaging or visual, having the convenience of a permanent set up adds greatly to your enjoyment of exploring the night sky. Ideal for up to at least 16" (40cm) aperture telescopes and a variety of installations, also ideal for societies, schools, etc. The Pulsar Observatory dome is sectional in design, and is delivered in kit form. Alternatively, we can provide a complete installation service for you. Please Ring for details. The Pulsar Observatories 2.7 metre full height dome benefits from many advanced features.FEATURES Finest quality, weather proof GRP finishHigh quality locking system Simple design for self assembly Motorised dome rotation available Motorised dome shutters available Accessory storage bays availableAvailable in white (other colours - please call)Dimensions: Total Height approx 2.7 metres Dome Diameter approx 2.7 metres Door Height approx 1.1 metres Dome Aperture approx 0.7 metres CUSTOMER REQUIREMENTS: Before you place the order of any Observatory Dome system please make sure that your department of planning and building inspection does agree. Probably you need a certain building permission.The customer will need to provide a level concrete base to ensure secure fixing and dome operation. Have a look to our installation guide which gives you an example for a suitable base dimension. Various upgrades and accessories are available. The 2.7 metre Observatory Dome is available in white - for other colours please call. We can also supply a steel pier, that will complete the permanent installation of your telescope, giving you more space within the dome than your existing tripod. We can also fabricate custom height piers to suit your requirements. VIDEO:  https://www.pulsarastro.com/video-guides-27-w.aspFAQ:  https://www.pulsarastro.com/faqs-28-w.aspCustomer review: Philippe R. (France):2 years ago, I purchased from you a 2.7 m dome fully motorized settled in my backyard in the region of X. You shall be happy to know that I am very satisfied with this product which is reliable for operating in a remote control mode . The dome hosts a Ritchey Chretien Telescope or alternatively an refractor astrograph used mainly for deep sky imaging I let you inform Pulsar Dome https://www.astrobin.com/search/?q=cpafobinIMPORTANT NOTES:THIS PRODUCT CAN`T BE ORDERED ONLINE BUT BY PHONE CALL OR E-MAIL.  AFTER PLACING THE ORDER YOU WILL RECEIVE A SEPARATE SALES CONTRACT FROM BRESSER.THERE WILL BE A DELIVERY CHARGE FOR THE OBSERVATORY, PRICE ACCORDING TO LOCATION - PLEASE E-MAIL US OR RING FOR DETAILS. AVAILABLE FROM STOCK IN GERMANY OR FOR CUSTOMIZED PRODUCTS THE DELIVERY TIME IS: 6-8 WEEKS APPROX. Save cash money ! PULSAR domes are transported safely on oversized, individually manufactured pallets with special dimensions, which quickly make transport by freight forwarder expensive. Therefore, it would be possible for all customers to pick up their own PULSAR dome with their own transporter or trailer from BRESSER GmbH Rhede/Westphalia, GERMANY, by arrangement.

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
