Several years ago I bought a used Meade 8'' (MTS-SC8) OTA and later a Meade GPS Mount for it.
After several years of snow white sleeping in the basement I recently dug it out to get it upgraded.
After doing several replacements and further upgrades I would like to clean the optics.
Besides the dusty mirrors, the corrector plate has some residues which look like dew but are permanently there.
The residues appear to be at the outer and inner side, where I checked the outer one and I can wipe it off.
When I tried to loosen the screws for the corrector plate, I found the HEX connection already worn out.
I tried a little with my set of HEX tools (cheap ones from ebay) but decided to buy a good brand screw driver for the 1/16 HEX connection, not to beat it up even more.
My golden rule is, if a screw is making trouble coming out, it should not be going in again.
Therefore I am looking for replacements. Since I live in Germany, shops for inch threaded screws (I guess they are not metric) are hard to find and I would have to order it online without the opportunity to try it first.
Therefore I wonder if someone can tell me the specs of this screws.
Thanks a lot
