Hello there, CMDR Cheapmilk here 
I have been an explorer for ages in this game and am currently sitting at the Ranger rank of exploration. The bad thing is...I kinda learned to hate it more than to love it. It is a very time time consuming profession and also not rewarding at all compared to the time spent doing other things. Sure for beginners scanning 5 stars and some planets might be perfect to start out, but the more you advance into the game the less exploration starts to matter. I believe thats because of the lack of more equipment and some "quality of life" tweaks like progression bars while scanning a body. So I've got some suggestions which would, in my opinion, make exploration a viable profession again. Here we go :
-Ultra Light Alloys
Used at the Bulkheads section, reducing the weight of the ship significantly as also reducing its armor.
Example : ASP Explorer with default alloys jumps 34LY, ASP Explorer with Ultra Light Alloys jumps 38LY.
-Advanced Surface Scanner
The next level of the Detailed Surface Scanner, yielding more profits after a scan.
-Scanner Boosters
Used at Utility Mounts. Significantly boosts the range of your scanner, so you don't have to come close to bodies to scan them.
-Scan Accelerator
Used at the Internal Compartment section, just like Shield Generators or Fuel Scoops. Reduces the time to scan bodies and ships.
-Turreted Scanner
Used at Utility Mounts. You won't need to face the object you are scanning. This would be especially useful for ships which don't manouver well.
-Add small-medium ships for exploration.
Those being fast and manouverable, but also not having any hardpoints, just utility mounts and also being light. I know it is extremely hard to implement new ships as well as to model them...but maybe you could give it a try
-Make even small Black Holes more dangerous and remove their exclusion zone.
Those are all suggestions I have for now, maybe i'll come up with more stuff
Fly safe CMDRs ^^
