Davo, I think your first post is already off topic. Moderators, where are you? Quick! Change the thread title to something more descriptive, like "Whose telescope reigns supreme?". Hehehe...
After a few JD & cokes and Bacardis, it does not matter all that much. They all seem to go out of collimation because they start producing blurry images. Also some mysterious reflections seem to develop because there is strong ghosting on every planet and star. If you have a binoviewer it becomes completely useless. Maybe it's a chemical reaction between the Coke fumes and the delicate optical components.
