The problem with the widefield is the Ha is so dominant and it ends up too red. That delicate bluish centre nebula can get swamped.
Closeup you get the pillars of creation and with a sharp image that is always impressive.
I did not know there was a lot of O111 in this area. That is a good formula and does work well on some objects.
