Quote:Those push pull screws work fine for tweeking those. I have one and was slightly out.
Here lies the problem, one of the problems with the 7" Mak is the large image shift from the mirror, it is enough that unless you pull it apart and address it the system can be perfect pointed west but point it up and it is out again.
Also make sure the meniscus holder is not too tight!
they work best when like a refractor lens there is a tiny rattle to it.
