Here is a new topic I believe:
The focuser on my Z12 does not mate flush with the OTA. The focuser base is curved for a smaller tube probably because they are more popular. There is a gap where light, dust, spiders, whatever can get inside.
To make matters worse, I needed to shim the focuser to square it to the OTA to get it properly collimated.
Now I have an even bigger gap and I'm wondering how to seal it.
I suspect a caulking gun is not the way to go......any ideas out there?
Thanks, Dave Y
I'm all for cheaper solutions, but you might consider just unscrewing the hex nuts in the base, and replacing it with a 12" base, which you might be able to get from Agena or somewhere else - but you'd have to make sure the new base will fit your focuser. For something giving you that much trouble, seems like it would be worth it.
