Where is the place to find the quest for the HM? Is it on White Nova? (im Empire)

Follow-up question. I've noticed that some of the HM's need unlocking by doing the normal mode flashpoint? As far as know i know that Boarding Party has this demand. Is there any more FP's you need to do on normal to get access to HM? Thanks!

I just turned 50 in the weekend and i have some questions regarding flashpoints. I've tried to read the sticky posts regarding this but i just can't understand some things. What flashpoints should i start with at 50? Can i go HM on some of them with a little pvp gear? Would like a guide for flashpoints/operations for us newbies that almost never been doing pve before. Thanks alot!
