I happened to be looking on the Celestron site at a page explaining RA and DEC and did a double-take upon inspecting their diagram more closely.
No, it is not the mispelled "Longitute"(sic), but something much more glaringly wrong (two things, actually), which immediately caused me to think of my old professor Francis Wright's favorite saying, "Constant vigilance!"
In all, I counted 5 errors just in the first four paragraphs and diagrams. For fun, can you find all of them?
All of this of course strikes me as utterly crazy given that Celestron as a major telescope manufacturer! Good thing they aren't in the celnav business!
