Is it possable to see how the orchestra pit opens?

I agree with Jodi Pearson answer.

I also think if you seat in the front pew early before the orchestra starts, you will see how it opens and closes. This is from the congregation's perspective.

.only if you are in the orchestra.

If you're inquiring about the rising of the pit, only if you're in the orchestra. Either way the only people that see it doing anything other than going up and down are Dr. Stanley, Dr. George, the choir, the orchestra, and Security.
