if i were you id be looking at the APM units available either in the US or direct from APM in germany, the semi APO are about 1100US, the APO are $3k -either will be a better buy
you will need to grab either a serious fluid head & tripod to mount, or something ike a unistar to mount them
the build quality on the 25x100 celestron will be sub-par, many of the sky masters can't hold collimation
have you ever used big binos -they are an acquired taste -best to try them before dropping that king of coin
