    Hi Andrei,

    These are neat images too. I do have a question, though. I'm wondering why the HST image does not have a large red component since the LRGB+HaOIIISII does. I would think the Ha would dominate the HST image.

    Hi Dick,

    HST is the special palette and you can find many types of this palette. I use as shown on the attached screenshot, but sometimes change the coefficients to get more information picture.

    Andrei, this is wonderful! I think you can see the effect of jets? Does this have a neutron star at its center?

    Bob, thanks.

    It is white dwarf in the center, not neutron star.
