Observatory axis N/S or E/W?
All else being equal, such as the horizons on all sides are about equal, light pollution isn't significantly different in any particular direction, there's plenty of space to put it anywhere I'd like to put it, and there are no other geographical quirks of my site to consider...
Should I align my rectangular roll off roof observatory such that the long axis, and therefore preferred view of horizons, goes north-south, or east-west?
Anyone got any strongly held views? I'm thinking favour north-south because I figure objects will rotate into view e-w anyway, and perhaps arguably I'm exposing less wall to direct midday sunlight, but is there a compelling counterargument for E-W?
