Build Question

[BRYANW57]

Long time follower, first time poster (as I just registered).
Question: I am planning on getting the 7.7x13x5 enclosure from Carl's Place (16:9 ratio) and hitting from 10' feet. My projector is a Panasonic VZM51U, which has 44% vertical lens shift, 20% horizontal lens shift, plus 25*/35* vertical/horizonal keystone correction (respectively). Also, I have 10.5' ceilings to mount the projector. Will I have any issues with shadows, etc.? It has a throw ratio of 1.09 - 1.77 and 1.6x optical zoom.
Please let me know your thoughts and appreciate everybody's expertise!

To avoid shadows, you want it as close to the screen as you can get it. Projector centrals throw says you can get it about 15' from the screen. With 10' ceilings, I think you will be fine, but you will probably want to do the math based on how high you can mount the projector.
