Recoating corrector plate????

A couple of questions.....

I got a recently acquired Edmund Astroscan.

The glass on the front looks "streaky" like the coating is deteriorated. Can this be recoated??

How do you collimate this little gem?

Thanks so much

It isn't a corrector, it's just an optical flat window to hold the secondary and seal the tube. I imagine if you could get the thing out someone could recoat it, but that's speculation.

You don't collimate it. That's the biggest lack on those scopes, probably. They are "permanently collimated" or as th case may be, "permanently miscollimated."
