StarXterminator taking comet detail in Linear State.

Matthew Hughes

Hi there,
I'm following the Comet processing tutorial and I'm having issue with StarXTerminator stealing some detail from the head of the comet (Leonard A1). Especially in green channel. I've tried making a mask with the Game script but it didn't really work as it produced its own artifacts. I also tried AI versions 5 through 7 and still no joy.
Starnet++ had weird artifacts as well in the linear state.
Is there another way I could extract the stars without loosing detail in the comets head?

Thanks
Matt

    Hi everyone,

    Ok I had a play around with all of the mask types in the Game Script.
    I'm I was able to protect the head of the comet by using an aggressive "Binary" mask. Luckily the comet head was not in front of, or just next too, a star so a circle shape did the trick and I managed to get a clean starless image without removing detail from the head.
    I will have to apply the game script individually to each image as the comet moves. Better make another coffee......

    Info for anyone else.
