For this reason choose the blocking filter that best suits your requirements for the system. It’s important to realize that a larger blocking filter is recommended for imaging due to the need for in-focus of the camera.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eB600 – Visual Use\u003c\/li\u003e\n\u003cli\u003eB1200 – Imaging and Visual Use\u003c\/li\u003e\n\u003cli\u003eB1200 – Visual Use\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/luntsolarsystems.com\/product\/lunt-blocking-filters-b600-b1200-b1800\/\"\u003eB1800\u003c\/a\u003e – Imaging and Visual Use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eRemoving the LS50FHa Solar Filter for night use\u003c\/h4\u003e\n\u003cp\u003eThe Lunt ED refractors are designed to retrofitted with the LS50FHa Hydrogen-alpha Filter.  In this way you can use the ED telescopes during the day.
