  1. :

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

    • Sam Wen

      :

      it includes the OIII, HA and SII, but not Na

  2. :

    – “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?

    • Sam Wen

      :

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

  3. :

    Sorry, but I haven’t understood the answer. The automatic pervodchik badly translates the answer.

  4. :

    Sorry, but I haven’t understood the answer. The machine translator badly translates the answer.

    • Sam Wen

      :

      they are just R G B L filters, not narrow banding filters

  5. :

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

    • Sam Wen

      :

      there is very small difference depends on the scope and wavelength

  6. :

    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)!

    • Sam Wen

      :

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

  7. :

    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!

    • Sam Wen

      :

      our 31mm and 36mm filter will come next month

  8. :

    Will the new 31mm / 36mm filter sets allow full illumination of ASI1600MM with the f/2 Celestron RASA?

    • Sam Wen

      :

      yes

  9. :

    Is this good for cooled 174mm too? Can I also use the EFWmini with 174mm?

    • Sam Wen

      :

      of course

  10. :

    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

    • Sam Wen

      :

      they are already available on our website

  11. :

    Sorry, I was meant to add I am looking at the 1600mm-c as my next camera.

  12. :

    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.
    Jimmy

    • Sam Wen

      :

      yes, you can use the new one which is better

  13. :

    I forgot it would 1.25″ filters
    Jimmy

  14. :

    Is this set better than cheaper LRGB set for ASI120MM-S usage or it doesn’t matter?

    • Sam Wen

      :

      yes, new RGBL is better than the old one

    • Sam Wen

      :

      this new one has better color balance

  15. :

  16. :

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

    thanks!
