  2. Thanks for the offer and the info. I think I am alright but if you could post a picture it would be much appreciated. Cheers, Mark
  3. Hi there, I have acquired a second-hand Revelation 12 inch Dobsonian telescope which unfortunately is missing 2 of the 3 primary mirror holding bolts and all 3 of the primary mirror collimation bolts (not sure of my terminology here by holding bolts I mean the ones with the screw slot head and the collimation bolts are the ones you adjust with the hex key). I can get bolts which will do the job but I would like to obtain original or near original ones to get the scope looking good. Has anybody got some laying around (long shot I know) or do you know where I can get hold of them? Also can someone confirm the parts involved in supporting the primary mirror. I think that the holding bolts go through the telescope base then through a spring then into the bolt hole of the mirror support bracket. I think that the colliamation bolts go through the telescope base and press the mirror support bracket which allow you to adjust the mirror. Any help or ideas appreciated. Thanks! Mark
