C11 correction

Hi,

I have start tested a C11 scope and I have found some spherical aberration. Is it possible to fix it replacing some part of the optics? (corrector, primary or secondary?).

Thanks

Where are you gonna get a corrector with the proper prescription for your optical system?

Be aware that a compound scope will NOT produce those pretty star test patterns you see with Newts. It's likely you've got a good scope that will perform well.

My advice? Try the scope on the planets and see how it performs. Chances are you've nothing to worry about.
