Ndi kapangidwe kake ka dual narrowband pass-through, fyuluta ya Kson 1.25′′ O-III imatseka molondola mzere wotulutsa mpweya wa ionizing ndipo imasefa bwino kuposa 90% ya kuipitsidwa kwa kuwala kwa m'mizinda (monga nyali za sodium ndi ma band osokoneza nyali za mercury). Imatha kuchepetsa kuwala kwa thambo lakumbuyo ndi nyenyezi 2-3, ndikukweza kwambiri chiŵerengero cha chizindikiro-ku-phokoso cha zolinga monga mapulaneti​

Fyuluta iyi imagwirizana ndi zosefera zamaso za telescope za mainchesi 1.25, zomwe ndi zosavuta komanso zosinthasintha, ndipo zitha kuphatikizidwa bwino mu kasinthidwe kanu ka telescope.​

Zikuphatikizapo:
Kson 1.25′′ O-III fyuluta (galasi lowala, mphete ya galasi ya aluminiyamu yotsutsana ndi kusintha);
Bokosi losungiramo zinthu la ABS losagwedezeka (logwirizana ndi muyezo wa IP54 wosalowa fumbi, kabati ya silicone yomangidwa mkati yosalowa chinyezi).
