    I really did try and find a negative or two. Hopefully that won't happen at the first light.

    One negative, as sort of noted, is the size of the mounting foot. It's fine for a photo tripod but for a dovetail like my Twilight I the size is a bit worrisome. It also precludes altering the balance. The added rail remedies the issue and also allowed me to add a safety stop.

    Another slight negative is the weight. Then again, with the build quality, the weight is a consequence of an outstanding aspect of the scope. Although much more compact it weighs about the same as my C80ED.

    Looks like a great buy: well done! Why can't I ever find sellers who actually want (and insist on!) less than I am prepared to pay?

    Looking forward to "first light".

    All the best,

    Dean

    It was a unique experience to have a seller who wanted $40 less than I offered especially when I was the one that solicited the sale. With the scarcity of the AT72 and the "like new" condition I felt my higher offer was warranted. It's also true that there are a lot of truly great people in this hobby.

    Just as an FYI, my research shows that the Orion Eon 72 (discontinued) is outwardly the same scope as the AT72ED. I can't say for sure as to the optics but as it is a doublet using FPL-51 it's possibly the same as the AT. I can't say for sure as to the coatings or whether Astronomics tweaked it. The Orion manual, which is online, was much better providing info on how to adjust focuser tension. I plan to lighten it just a hair. The previous owner is into AP so he might have increased tension a bit to handle the weight.

    Other than briefly being able to watch a beautiful moonrise last night it has been rain and clouds, but, we had a wonderful sunset.

    The ongoing waiting list says something about what you have. I expect you will get a lot of enjoyment out of it. If I ever tire of taking introductory level scopes and tweaking them, something like what you have could be just the thing for me as well!
