    Are the LRGB and Narrowband 36mm filters still with bandpass of 7nm?

    Hi!
    I’d like to understand if these filters are optimized for the ZWO ASI 1600 mono as for the filters that you presented in the 1.25″ format.
    I wanto to couple my Celestron C8 reduced at f/6.3 with a ZWO ASI 1600 MM-C + filter wheel and LRGB filters.
    Thank you in advance!

    Hi. I am interested in your full 36mm filter set s part of a kit, I am confused about the light transmittance amount. Your 31mm page conflicts itself – in the text it says 80% transmittance but the graph says 90%. The 36mm page says better than 92 % transmittance. Can you clarify this please ? Thanks

      Hi Kelvin
      we write more than 92% transmission at passband. graphy is taken by a filter sample, each filter will have a little differnece of passband.

    Hello,

    is it important in which orientation the filters are placed in the filter wheel, i.e. which side faces the CCD and which towards the scope?

    Thanks!

    Hi,

    I am considering your 1600MM kit with 7 36mm filters. Are these unmounted filters?

    Thank you,
