I have a antares 6" mirror that is about 5 months old and it has started looking very hazy as well as the diagonal.
Could this just be the coatings failing or maybe the mirror is just not polished out all the way?
It seemed alright when i first got it. Where is a good place to get it recoated? Any opinions are appreciated.

Its unusual to see a coating fail that quickly, and
two different mirrors in the same scope would be even
a bit more surprising. I think a more likely scenario
is that both mirrors got some sort of junk on them.
Maybe the scope was left in the sun, got hot, and
vapors from grease and paint left some residue?
Sticky stuff given off by trees can also make them look hazy.
I'd try cleaning them first with standard methods.
Use some solution with solvent properties like
91% rubbing alcohol.
