Anyone got any good info on dome seeing, which I take to be due to highly localised thermal turbulence?
I seem to have been getting consistently better seeing results in an open enclosure than in previous partially sealed environments and am guessing that this could be due to better thermal conditions in the open. Found a good reference to dome (and mirror) seeing that indicates that dome seeing may increase by as much as 0.28 arcsec for every 1C difference between dome air temp and outside air temp (large telescopes). This is huge if it applies to our little systems. It might also suggest that dew heaters are not the smartest idea.
Any thoughts? Regards Ray
