This image shows the two scopes set up in the observatory. As can be seen, it is a bit tight but I can actaully use both at the same time within reason. When using only one scope at a time, there is plenty of room to move around even with both set up.
Note: This image makes it look like the LX90 is just about up against the wall but in fact, it is nearly 3 feet off the right side (east) wall.
