Barlow Q
Hi there
I have a 2" 2x ED barlow which I've been using with my f7.5 80mm refractor, with a 2 inch diagonal. Was wondering if there is a difference in magnification when I put this before the diagonal? Unfortunately, I cannot seem to get focus when it is used "after" the diagonal.
There seems to be an increase but I'm not sure if I am just imagining it.
Thanks
Andrew
