Filtry Filtr 50mm Ha Etalon z B1200 do wyciągu okularowego 2"

Because the LS50 has an estimated bandpass of <0.70 Angstroms it is capable of providing high contrast views of both surface and edge detail. Adding an additional etalon system will reduce the bandpass to ~<0.50 (dependant upon scope) allowing for higher resolution viewing and/or imaging.
