C14 primary mirrorPosted By Don O'Cain |
When you say the primary is out of line are you sure it's not the secondary,on the secondary and the primary there is an orientation mark and a number that lines up the primary and secondary at the factory,you could think of it as matching I guess.I just finished dismantling a C14 and I noticed this marking on the secondary and when I dismantled the primary the orientation was also marked.In my case it was ' X618 " with an arrow to the outer edge,same on the secondary. If I remember well you can see the end of the marking on the edge of the mirror on both mirrors.I do think they lined up.NOT 100 % SURE ON THAT( can't visualize it from memory )
Just wondering did you spin the secondary around when Hyperstaring or when cleaning the secondary if you removed it from the holder.
There is no way to shim the back side of the primary and it's mounted pretty tightly to the center light return tube.But that said you could open the OTA and with white dust free gloves move the primary to see if there is any freeplay at the center tube when you rock the primary east /west or north / south.I would be very surprised if it had freeplay but everything is possible.
