    I have the ASI1600mm Pro and I bought your kit that includes the new LRGB and the narrowband filters (1.25″). I use SkyTools4 Imaging to plan my imaging sessions and they are looking for a text flle that describes each filter. Do you have this file available for the each of the filters? I could estimate the values from your graphs but would certainly rather have a more accurate file to import.

    Here’s the structure of the file format (from ST4 Help file):

    “The transmission data is in pairs of numbers, separated by aspace, one pair per line. The first number is the wavelength in nanometers (nm), followed by a space. The second number is the optical transmission of the filter in percent, a value between 0.0 and 100.0, where 0 is no transmission, and 100 will pass 100% of the light. There can be up to 150 pairs in the file. The wavelengths should be provided at regular intervals (50 nm below).

    The first and last pairs must have a transmisison of zero!”

    Example file:

    250 0.0
    300 20
    350 40
    400 90
    450 95
    500 98
    550 90.0
    600 50
    650 10
    700 0

    Appreciate any help you can provide.

    Hi I received the new LRGB but there was no label on the box. Is there a way to check physically whether I have received “New LRGB optimized for ASI1600mm vs the cheaper filter? Thanks.

      Hi
      We place the lable in the different place for new filters and old filters.
      For the new filters, the label is usually on the plastic bag of the filters.
      Could you send us the picture? so we could tell if your filter set is new one.
      You could send it to support@zwoptical.com

    Hi Sam,
    Have you tried these with other brand cameras, like Atik?

    thanks!

    Will these work the same with asi 120 mm in a 6″ f4 astrograph ,as opposed to the other set of filters not optimized for the asi 1600.

    Hi, when will you release narrowband filter set (Ha, OIII and SII)?
    Will they come in 1.25″ or 31mm? (31mm will be ok with f/4 scope?)
    What is the estimated price?
    Thanks

    I have a F/5 telescope. To avoid vignetting, it’s better to use 31mm filter. Do you make this same kit (for ASI1600) in 31 mm ?? I can’t found it on your web page?? Thanks!

    Hello Sam,
    I’ve just received my new set of LRGB filters for my new ASI1600MM cooled camera.
    In the box there’s an UV/IR cut filter instead of the Luminence filter. Is the same as an L filter and if not, what is the difference?

    With thanks (Xie xie)!

      :

      L is just the UV/IR cut filter, they are the same

    Are these filters parfocal or will I need to refocus after swapping?

      there is very small difference depends on the scope and wavelength

    – “it includes the OIII, HA and SII, but not Na”

    Means when using these filters there is no need to buy OIII, HA and SII?

      you need to buy if you wish to do narrow banding imaging

    The transmission curve jpg for these filters is confusing. Are these filters discrete OIII, NA, Ha and SII or just better quality LRBG filters?
