The other work done was "cleaning and collimating". The scope still has very noticeable sherical abberation. Jupiter and Saturn barely tolerate 100X and even that is marginal. Cassini's division is only suspected most of the time and is never clear. BUYER BEWARE: It appears that Celestron's definition of "diffraction limited" has changed recently. You have a defective scope. Either the mirrors are figured wrong or the corrector plate is improperly matched. Send it back to Celestron, scream, rant, and rave....and they will fix it to near perfection. I have owned over 60 scopes, and the only 3 with "bad" optics were all premium refractors. Two AP Travelers (YES Travelers) and one Meade 127ED. One Traveler needed to be refigured, and the other needed to have the lens remounted and re-oil spaced. The Meade needed to have an element replaced. Out of the 3 C5s I owned, all were gems!!! You were just unlucky, that's all. The moral of the story is...Buyer beware, no matter from whom you buy.... |
