"Considered as a collector of rare and precious things, the amateur astronomer has a great advantage over amateurs in other fields ... the amateur astronomer has access at all times to the original objects of his study; the masterworks of the heavens belong to him as much as to the great observatories of the world. And there is no privilege like that of being allowed to stand in the presence of the original." --Robert Burnham Jr, Burnham's Celestial Handbook

The XLT coatings on my celestron have the secondary looking like its levitating without glass support. You guys really ought to consider it. Pete
