Mickcoll Posted January 12, 2014 Share Posted January 12, 2014 Could anybody please advise me regarding updating my celestron 127 standard diagonal. I have upgraded my eye pieces (bsts) but is it worth a better diagonal and also which one. Thanks Link to comment Share on other sites More sharing options...
Peter Drew Posted January 12, 2014 Share Posted January 12, 2014 I replaced my C8 stock diagonal with a Teleview dielectric 1.25" unit. I can't say that I noticed a great deal of improvement but a least I know that it is good quality and that I remain the "weak link in the chain".

CodnorPaul Posted January 12, 2014 Share Posted January 12, 2014 The stock Celestron prism is actually fairly good - the only reason I upgraded was so I could use 2" EPs so the answer really is why do you want to upgrade? Visually there will not be a huge gain on that OTA Link to comment Share on other sites More sharing options...
Mickcoll Posted January 13, 2014 Author Share Posted January 13, 2014 Thanks for the advise. But I am still confused (I am a beginner) as I thought that the standard eypieces are poor quality (but the diagonal is ok I )thought upgrading all standard equipment would make a difference Even though it's only a 127 Am I wasting my money upgrading my diagonal I would appreciate your advise thanks.

John Posted January 13, 2014 Share Posted January 13, 2014 Upgrading the stock eyepieces will make more difference to the views than upgrading the stock diagonal. Link to comment Share on other sites More sharing options...
