Recently i started to use BAADER ULTRA-NARROWBAND H-ALPHA 3,5 NM FILTER and i am very pleased !

Because my regular BAADER S-II 8 and O-III 8.5 filters create much larger and blured stars than Ha 3.5 i am considering to order also ULTRA-NARROWBAND 4.5 nm OIII and SII but before i do that i need to know if this filters produce stars with the same size and similar halo to Ha 3.5 nm ??

Please send me answer or link to sites where i can find this information !
