    Hello!
    Why is the transmission curve of these filters not reaching the ultraviolet?
    Are these filters suitable for shooting planets on a monochrome camera ZWO ASI 120MM?

    P.S. By the way, thanks for the nice camera!

      The camera efficiency does not have too much difference in UV.
      Yes these filters can be used.
      Thank you for supporting us!

    To what focal ratio are these filters parfocal to? What are the tolerances of the filter thickness?

      :

      the tolerances of the filter thickness is around 0.05mm
      parfocal depends on optics

    Would these 1.25 filters work well with the ASI290MM on an Edge C11?

    Hi Sam,

    Are these filters parfocal or some focus adjustement is needed for RGB imaging?

    Thanks in advance!
