I'd go along with that Dave. I have a DSLR, but I have sometimes wondered if a CCD, especially one of the latest models, would give an advantage. If it does, is it worth the huge cost of these items? Articles could be bench marked against a commonly owned item.
I am bewildered about the choice of telescopes today, I must admit. At one time a goto mount cost more than the optical tube, but today it seems to make less difference. Is the mechanism of a manual telescope better than that of the modern goto equivalent? Is that why the price difference is not so great? Or is it simply that more gotos are produced and therefore cheaper than a more expensive, but shorter run of manual ones? Coatings can make a big difference to the price, but like you I rarely see an explanation about them.
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.
