In a solar installation, ultraviolet and infrared light mainly provide extra heat that you don't need. This DayStar UV\/IR filter (2 inch) blocks that light and allows the visible light to pass through. In an installation with an H-alpha filter like the Quark, it limits the amount of heat and unwanted light that reaches the filter.<\/p>\n\n\n\n

The filter comes in a focuser or diagonal with 2 inch filter thread, so check that first. Similar filters are available from us. UV\/IR-cut corrective filters<\/a>.<\/p>\n\n\n\n

Whether an UV\/IR blocking filter for your telescope is sufficient, or whether you also need an energy rejection filter for the opening, depends on the opening and the type of telescope. Feel free to ask us before ordering. This filter is not a solar filter itself: never look at the sun with it without a full H-alpha system. In our guide on sunscreens<\/a> Read more about safe observation.<\/p>\n\n\n\n

Is a pre-filter necessary? For example, look at the ERF prefilter E-110N75<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"
