The zenith mirror contains the blocking filter is internally and is equipped with a holder for 1.25 inch eyepieces. This telescope's ease of use and simple setup makes it ideal for getting started with H-Alpha solar observation. \u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cem\u003eNote: \u003cspan data-mce-fragment=\"1\"\u003eLunt Solar telescopes come with B500, B600 \u0026amp; B1200 filters with the larger ones providing a wider field of view and less shading on the edges. \u003c\/span\u003eThese telescopes are ideal of visual observation of the Sun however as they have a very small back focus, only cameras with a very sort distance to the sensor can be used for photography.\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAperture: 40mm (2-lens lens)\u003c\/li\u003e\n\u003cli\u003eFocal length: 400mm\u003c\/li\u003e\n\u003cli\u003eHalf-value width: \u0026lt; 0.7 Angström\u003c\/li\u003e\n\u003cli\u003eTuning: Mechanical tilt tuning\u003c\/li\u003e\n\u003cli\u003eBlocking Filter: B500 with 1.25 inch connector\u003c\/li\u003e\n\u003cli\u003eFocuser: Helical focuser\u003c\/li\u003e\n\u003cli\u003eDovetail : Standard GP Vixen\u003c\/li\u003e\n\u003cli\u003e1\/4-20 thread (standard thread for photo tripods)\u003c\/li\u003e\n\u003cli\u003eSun viewfinder included\u003c\/li\u003e\n\u003cli\u003eWeight: 1.2kg\u003c\/li\u003e\n\u003cli\u003eLength: 41cm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cem\u003eWhats included:\u003c\/em\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003col\u003e\n\u003cli\u003eLS40THa Solar Telescope\u003c\/li\u003e\n\u003cli\u003eB500 Blocking Filter in Zenith Mirror\u003c\/li\u003e\n\u003cli\u003e1.25 inch Helical focuser\u003c\/li\u003e\n\u003cli\u003eGP Vixen rail\u003c\/li\u003e\n\u003cli\u003eSun Viewfinder\u003c\/li\u003e\n\u003cli\u003eOperating instructions\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Lunt Solar Systems","offers":[{"title":"Default Title","offer_id":42671937061107,"sku":"0551145","price":1468.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/LuntHaSolarTelescopeB500_2.jpg?v=1650118913","url":"https:\/\/www.horizonastronomy.ie\/en-dk\/products\/lunt-ls40tha-b500-h-alpha-solar-telescope","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
