    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!

      1.25″ filter is big enough for f6.3

    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.

    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?




    • Sam Wen


      you can follow the instruction, but it’s not so important from our test

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

    Thank you,


    • Sam Wen
