The eagle neb is showing exceptional resolution I hope you persist with the newtonian, they are a love of mine.

Yes spacers and coma correctors can be an issue for sure. Luckily the imaging circle is stopped down a fair bit when using the FFC so I can do without the MPCC. With the refractor there is enough back focus for the corrector (97mm) but you'll never fit an MPCC at 55mm. Unless you put it behind the AO. Then you have to extend the OAG. It can get messy. Haven't figured it all out yet.
