They might be a chain of galaxies, but they are a strange shade of red in DR10 images. Is this a filter problem?

They are either foreground stars in our own galaxy, or just an extragalactic object. I think this is some sort of masking artifact left in the CP.

These seem to be just very red objects. The images all look fine – most flux in the z, a bit in i, a bit in r, none in g.
Photo-zs are z~0.8

looks like distant gal. grouping on dr9 ○°°

It seems to have been a bad i-band exposure. Yes, the group appears normal in grz colors.

ahh, yeah, the i band was incorrectly masked.
