To be honest, there isn’t really a “best” time of year.  Some of our customers choose to install in the Summer/Autumn in order to avoid disrupting their observations during darker winter months – getting the kit ready for the new season – whereas some choose to install in Winter/Spring to avoid garden upheaval during the Summer months.  It depends on your priorities, but bear in mind that we take comprehensive steps to avoid damage to your garden/lawn so it shouldn’t need time to ‘recover’ after installation…. equally, the on-site part of installation is very quick, so you won’t be without your observing space for very long!
