I did try using an ap reducer (27tvph .75 and .67). But because the field was very flat in the first place and the ap reducers have a slight flattening effect, they induced field curvature. I have a vc200 reducer that I was going to try, but never got around to it.
Wow, that Centaurus A image is impressive and inspiring. The scope in question that was used to produce this image was a f/10.5 wasn't it.
