Just came in from some testing, coma is no longer present with any low to mid range EP, but conditions did not favour going above 200x at this time. I did have to tweak the primary slightly to get rid of the coma that was still there after the bench setup. So I am confident the primary is good now. Focuser positions are where I expected, within a mm or two of original recorded position.
Star testing shows good Airy disk with centred secondary shadow, no astigmatism, nor spherical aberration. I need to get one night of very good Seeing to finish off testng above 200x, but it is looking very good at this point. And my star testing result also ties in nicely with my bench test setup,
