Here are some pictures to show the wall height of the new taller walls versus the standard wall height. I am 5'8" tall to give you an idea of height. The standard wall height is 4' tall, while the taller wall height option is 5'3" tall. The standard door height is 3'6" tall, while the taller wall height is 4'9" tall. I realize some people will be using the POD-S for strictly automated imaging, and may not want the taller walls, but the taller walls allow more head room to maneuver in the POD without ducking down for the dome.
With the taller walls, I bought a 12" pier extension block from SkyShed to give my existing pier more height.
