Thanks Frank, Yes, I have seen that scale and, in fact, I used it before switching to the 10 point scale. Using your scale, my average seeing looks like a 2 in my 10" and a 3 in my 5". Occasionally I get nights with 4 seeing in the 5" but only a 3 in the 10". I like the idea of your balcony setup. Getting up above the ground level probably does help quite a bit. There are plenty of houses on top of the hills here in FH but, unfortunately, I couldn't afford any of them ;) Regards Bill -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
