So there is nothing wrong with either your scope or the eyepieces.
My GSO 12" came with a 32mm and a set of 25mm eps and the coma was very obvious in the 32 but not so in the 25mm 1.25" one that I initially used for most of my observing. If it reallty bothers you and you are wanting an inexpensive suggestion just get a 25mm 1.25" plossl and see how that goes. Cheers Malcolm

Hi Malcolm,
I have 40,30,20,15,10,6.5 & 4mm plossl in 1.25mm already. Their sharp as a tack, it's just disappointing the 2" is so bad. I've heard from others these 2" EP's are just nastie.
