Red stripes

    Does anyone know what are the two red lines in the picture? I've come across similar ones a couple of times already and I can't help but wonder what they are.. They don't look like satellite trails to me. Are they just optical artifacts?

    They're artifacts, basically some kind of reflection of light - in the g i band - from the bright star in the center. They don't appear to link directly back to the star because they're in a different Field, as you can see from the same image, when you tick the "Fields" box (under Advanced options).

    Yes, it's cool HII nebula, isn't it?

    UPDATE: red stripe = i band, not g band (silly me)
