I used to have a Meade 80mm Triplet APO and had no coma. Sounds like your scope is not collimated.
I should have indicated that the scope is fine visually. However, when imaging with a DSLR, I noticed coma in each of the four corners of the image frame. The amount of coma in each corner is the same, so is this still a collimation issue?

You can look into the Baader MPCC and see if it will work with the 80 mm.
