Red stars or camera noise

[si717]

So i went about more testing of my equipment lastnight

and i was wondering if one would know is this camera noise or red stars

iam using a full spetrum dslr filtered but in the test shots of NGC 869 there are alot more red than in the test shots of M45

both tests gots the same exposure time so id assume if noise both pictures should show the same

so is it stars or is it camera noise many thanks

Clearly the M45 needs colour balancing since it's green-dominated at the moment but you seem to have red stars in the right places. (There aren't many in M45 because it's a young cluster) So it looks fine to me.
