Hi All,

I'm currently in the process of designing a new remote observatory, and in my research I read a bit about "near seeing" (or ground seeing) and "Dome/instrument" seeing effects as opposed to "high altitude seeing". Apparently, 70 to 90% of your total seeing effects can be ground based seeing, and reading that 70% of the ground seeing is in the first 3 meters above ground level, has prompted me to build this observatory (which will be a roll off roof) as high off the ground as possible. Obviously, I will be taking other measures also to reduce the seeing immediately around the telescope and in the observatory.

In respect of this, I would be keen to hear of any others experience with building observatories high up and tall telescope piers.

thanks
Josh
