Well, I don't know how to fix the CP so you get good CPs, but here I prefer to put them manually. If you choose to try this I suggest that you can do only 2 CPs between each pair. Try to put them far from each other. I usually try to choose one on the bottom and one on the top of the images and sometimes I use 3 or 4 CPs. As you have a good hfov you probably will have very few image pairs and this wont take too much time. I usually do this in 10 images (Opteka 6.5mm in a 1.6 crop censor).
