Which IR Pass filter for planetary imaging?

Seems to have been covered somewhat in other forumns, but which IR pass filter will work more effectively for planetary imaging?

I have a 12.5" that gets used with a Skynix 2.0 camera and 5 x Powermate so imaging at that focal length I am always at my limit with light and more is better.

Looking at the Baader which kicks in at 640mn or the Astronomik which kicks in at 742mn and is nearly half the price. I have a set of Astronomic LRGB filters so hoping I will not have refocus between filters.

Look forward to opinions.
