Re: Replacing Secondary Lens for Nextar 6SE.

Celestron USA replied to some cloudynight forumers many years ago that the SCT set of optics are "matched" @ the factory , that's why no individual parts

Re: Looking for an upgrade

Change the ball shaped 90 degree "diagonal" to a 1.25" mirror diagonal and 32mm plossl.

Total cost $12 + $20 if bought online from overseas.
Big improvement over the original stuff that came packaged "free" with the Astromaster.
