So build an Observatory on stilts .... and don't tell anyone.
The precedent has been set ....
Joking of course but I can feel your frustration ..
I know you're losing the northern aspect, planets etc but how good is your southern view ?
I ask because I have no northern view due to a large volcanic hill. I marginally get a planetary chance at the highest point for a few hours although it is badly compromised by thermal and light problems. I do not have an Eastern at all, CBD, LP and trees to about 80* and my western sky gets to about 35* ona good night.
My southern SCP view and a slice of the sky from Nth 50 to Sth 30 and about 60* wide is it so I just have to be patient and wait till it all comes round next year.
Is this at all an option or viable ?
