Yes, I need a coma corrector to get some improvement on the 30mm 80 deg eyepiece I bought from Bintel - their chinese version for a hundred something dollars. I liked it in my 8" f6. As expected, more coma is seen in my 12" f5, but I still like it. I know there is a limit to what could be achieved with a cheap eyepiece, but I want to give it a go. Strange when the accessory (the corrector) costs at least two times the price of the eyepiece
