Ha sorry, should have read the scope specs. It is indeed an APO. Weird. Shouldn't do that then.
PS: had a look at your shots. The blue is indeed bloated compared to the red and the green channels so there is a slight issue with colour correction although not as bad as an ED doublet. I've seen
worse. Are you using any kind of field flatener ore corrector/reducer in the imaging train. That might come from other glass in the system.
