A large number of collisions with neutron/wd stars happen because the collision sphere disappears quickly and only appears again at the last moment. Having a way to keep it on at all time would greatly increase safety.
I know exactly what you mean. Until FDEV actually fixes their previous fix for hiding these when going to slow, I have the following tip to give to you:
Always, ALWAYS, ALWAYS target the Neutron star, the exclusion zone is between 13-15 LS, so go with 15 LS as this is the most common safe distance to be to a Neutron star without emergency drop from super cruise.
Now the most tricky part is how you will be able to fly around the star, as you most of the time, faces the Neutron star straight between the cones. so aim at one cone a bit out from the star and watch your distance, and then learn when to go parallel with the Neutron star and when to turn away from the Neutron star and try to enter the cone. This part is just practice and learning by doing.
It should always be shown if showing orbital lines is active, this option can be put on a keybind, for easy toggle for those who do not like orbital lines, and when trying to super charge your FSD at a Neutron star (or white dwarf), there are rarely any disturbing orbital lines to be seen anyway.
