Shaun looking at jupiter with a 16 inch will make you blind in that eye , so bright you will loose dark adaption so you are better off making an 'off axis aperature mask' about 6 inches in diameter , giving about a 6 inch f12 un-obstructed telescope , now you are talking !!!
.
The luna/planetary views thru that would be awsome ! .
Thats the 1800mm fl of the 16 inch divided by the 150mm aperature mask's diameter , thats 12 so it will be f12 .
