Phantom Stars?

Hey guys, you might have seen my thread in the Deep Space, of NGC 3324. Any idea what causes phantom stars? Attached to images, one of the RGB data, and another of the RGB combined with the Ha. I don't know what the faint blurry patches are, but I don't think they are stars. They aren't present in the Ha data, or in the RGB?

Figured it out. If you do the combination with an active mask, it happens….Problem solved..

Good detective work, Erik! Generally, you wouldn't want to do a LRGBCombination with a mask active. It's mostly an all-or-nothing operation.
