Lichtvervuiling en maanlicht worden vrijwel volledig onderdrukt, waardoor zwakke structuren in HII-gebieden, supernovaresten en planetaire nevels met hoog contrast zichtbaar worden.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Het 36 mm formaat voorkomt vignettering bij camera's met grotere sensoren, zoals de ASI294MM en de ASI2600MM-serie. De filters zijn homofocaal met de ZWO LRGB-sets, dus je wisselt kanalen zonder opnieuw scherp te stellen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Features<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li>Drie smalbandfilters met 7 nm halfwaardebreedte<\/li>\n\n\n<li>36 mm formaat: geen vignettering op grote monosensoren<\/li>\n\n\n<li>Homofocaal met ZWO LRGB-filters: geen herfocussen<\/li>\n\n\n<li>Onderdrukt lichtvervuiling en maanlicht vrijwel volledig<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Compatibility<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Past in filterwielen met 36 mm sleuven, zoals de ZWO EFW 7x36mm.
