This isn't the secondary mirror, it's the secondary baffle which is normally glued to the inner face of the corrector lens. The secondary is an aluminised spot on the inner surface of the corrector. The whole front cell should unscrew and then you can retrieve the baffle and carefully glue it back on. Don't let the detatched baffle rattle around on the primary mirror as it will scratch the coatings.  :icon_biggrin:


1/2/2021 I also have the Meade etx90. The small disc is sliding off. It was bought in 1999. Tried to unscrew front of tube but very tight. Did not want to break something. Love my 90.pic attached
