Probably there is no “service centre” in HK, as most dealers are not favor in “after-sales-service”. As a user, you better learn to clean up C8 yourself. It is not so difficult to do provided you are the kind of DIY:
Basic awareness
1. Take off the front label ring with screwdriver.
2. Mark the glass lens (corrector) with pencil or whatever to identify its orientation, front/back side.
3. Remove the lens and the rim inserts from tube body carefully (not to break the glass !)
4. Clean the lens with distilled water and wip dry with clean cotton handkerchief.
5. Similar thoughts to clean the mirror ....
The rest can be worked out at your own. Remember to put the lens back in original orientation + front/back side. Also the star collimation after repair, which can be done with the 3 set-screws on the secondary mirror holder.
