I'm using an Orion 8 in. newt. on a lxd55 mount with 497 autostar hbx , I have gotten a lil' bit farther reading what other users have done. I finally setup in utilities but, still not quite there yet. I don't know what the aperture area is or something about ms in another area pertaining to scope view. I really need help with this , it's almost there this time around.
What's The Aperture Area M^2 And MS?
