Well, I spent a lot of time on the internet searching for spot diagrams on the Meade 127ED objectives. But not one to be found anywhere. cwy
I was just curious, knowing that it is not an APO but an ED. It is stated a few places that this objective has 4x the color correction of a Achromat, but nothing shown to prove it.
I guess it does not matter too much, I did not expect an APO for the price. smile Heck! For the price that I paid with the mount and all, a good Achromat would have been a decent price I think.

Yes, three to four times seems about right. Of course
I am just guessing the lens radii based on the glass types.
Only Meade knows for sure what they did.
