I am building an 8" Newt, Using the Newt20 program I can get the on-center ray and the 100% ray centered right in the middle of the focuser tube. But the 75% ray is off to the side. Is this the way it is supposed to be?? (I'm new at this). Will my telescope work properly?? If not, how do I fix it, Thank you for any answer you can give.
