Subject: ETX Baffle questions Sent: Sunday, May 20, 2001 10:52:41 From: firstname.lastname@example.org (Clay Sherrod) There are any number of ways to resecure the baffle tube for good. I recommend using four small "dots" of epoxy glue at 90 degree increments around the perimeter of the baffle tube itself; let it sit for about 20 seconds after appling the final "dot" and then carefully position into place. 1) The baffle probably does not need to be cleaned (if you are merely referring to the tube itself); brush it off with a shoe brush or soft cloth if need be; if any of the flat black paint shows through anything shiny, then you might apply some new flat black paint....make sure the paint has fully cured for several days before sealing the tube back up. 2) The best way of removing the glue from the glass is by rolling it gently with your finger; you must clean the inside surface AFTER doing this of all fingerprints and residue with the alcohol/distilled water solution. 3) If you cannot get the ring of tape from Meade that is made for this, I would suggest NOT using tape and using Epoxy glue instead. 4) Attach glue and/or tape ONLY to the baffle tube end ring, not the glass. 5) Center the baffled precisely with the outline of the secondary mirror; once done, the meniscus cell is fully aligned once you have screwed it back onto the end of the ETX scope.

Subject: Baffle Fix Sent: Friday, May 10, 2002 9:38:32 From: email@example.com A warning to anyone who is thinking of fixing the secondary baffle on any scope..... I have an ETX-90 RA. The secondary baffle had slipped down so I thought I'd repair it. I followed the directions for the secondary baffle fix on your site. All went well until I substituted a gel super glue for the two part epoxy. The problem is the glue reacted with the coatings on the element. The central aluminized spot is now discolored, looks a little like oil film on water, and there is a cloudy halo around both the inside and outside of the baffle. I have tried to remove the cloudy film to no avail........I believe I have ruined the secondary element...... I will be placing a wanted add with my next email.....Mike here: You might want to contact Meade and see what they can do for you.
