The field having some coma doesn't bother me in particular because my dob in not driven the object will always pass through the center of the field where correction is best.
Besides when its only at 75x mag with like 1.3 degrees field of view - objects aren't exactly flying through so a little nudge is easy to bring it back to center.

I've read mixed reports about the 20mm ES, although I'd assume a lot of people are a lot more particular/finicky than I am. I just pulled the trigger on an APM 20mm 100° (at a price much lower than the ES 20mm), so if Brisbane has a clear night without a full moon ever again, we'll see how it performs.
