faint line

by IKINAWANA

Notice the faint line running from the galaxy towards the bottom left corner of the picture? Is this something or just artifact? Should this be marked as "odd"?

Hi, sorry but it is only an artifact, these images are heavily processed. There are many funny lines and circles in the images when you look at them with such high magnification. They areas where images are sewn together, or cosmic ray hits removed.

Here's a different version of the same field, processed using different parameters (the orientation is different):

I don't see any faint line, and this field isn't really close to a Field boundary (capital F, because it's a technical SDSS term).
