Yeah, I felt courageous and did it myself (well, the wife provided an
extra pair of hands). The inside had a few bits of black specks, and I
easily removed them, using a camel-hair brush to clean the secondary.
I made sure to use some marked tape to ensure the alignment of the
corrector plate. I'll most probably need to collimate it a bit due to the
pressure of the screws and such. Hopefully tonight if it stays somewhat
clear.
Thanks for the advice!
