The H-alpha wavelength is the most impressive way to observe the sun, showing bulges at the edge of the sun, filaments and flares on the surface, and much more. An Etalon with mechanical tilt adjustment provides \u0026lt; 0.7 Angstrom bandwidth.\u003c\/p\u003e\n\n\u003cp\u003e Precise adjustment is achieved with its 1.25-inch helical focus. The blocking filter is the B500, suitable for visual observation of the sun. The star diagonal on which the blocking filter is installed is equipped as standard for the connection of 1.25 inch eyepieces.\u003c\/p\u003e\n\n\u003cp\u003e Its easy handling makes this telescope ideal for getting started in H-Alpha solar observation. Due to its compact dimensions it is a good travel telescope for experienced solar observers.\u003c\/p\u003e\n\n \u003cp\u003eLS40THa telescopes are available with your choice of B500, B600 or B1200 blocking filters. Larger blocking filters provide less edge obstruction and a larger field of view for visual observation and photography. Please note that these telescopes only have a very small back focus and therefore photography is a difficult task. We recommend special astro cameras for photography, which have a very short distance to the sensor, such as the BRESSER Full HD camera number 4959050.\u003c\/p\u003e\n\n\u003cp\u003e CHARACTERISTICS\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e Aperture: 40mm (no central obstruction, 2-lens refractor)\u003c\/li\u003e\n\n\u003cli\u003e Focal length: 400mm\u003c\/li\u003e\n\n\u003cli\u003e Bandwidth: \u0026lt;0.7 Angstrom\u003c\/li\u003e\n\n\u003cli\u003e Tuning: mechanical tilt\u003c\/li\u003e\n\n\u003cli\u003e Blocking filter: B500 with 1.25 inch connection\u003c\/li\u003e\n\n\u003cli\u003e Focuser: Helical focus\u003c\/li\u003e\n\n\u003cli\u003e Standard GP level dovetail bar\u003c\/li\u003e\n\n\u003cli\u003e 1\/4-20 thread base (standard thread for photography tripods)\u003c\/li\u003e\n\n\u003cli\u003e Solar finder included\u003c\/li\u003e\n\n\u003cli\u003e Weight: 1.2kg\u003c\/li\u003e\n\n\u003cli\u003e Length: 41cm\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e INCLUDES\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e LS40THa solar telescope\u003c\/li\u003e\n\n \u003cli\u003eB500 Blocking Filter in Star Diagonal Housing\u003c\/li\u003e\n\n\u003cli\u003e 1.25 inch helical focus\u003c\/li\u003e\n\n\u003cli\u003e Dovetail bar (GP level)\u003c\/li\u003e\n\n\u003cli\u003e solar finder\u003c\/li\u003e\n\n\u003cli\u003e Manual\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Lunt","offers":[{"title":"Default Title","offer_id":47813339316567,"sku":"551145","price":1363.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/91449013e5001d05b0f9fe035a007e17-0551145_m_1_v2.jpg?v=1710059952"}],"url":"https:\/\/astrotelescopios.com\/en-efta\/collections\/telescopios-solares.oembed","provider":"Astro Telescopios","version":"1.0","type":"link"}
