Well some of the journeys here made me feel my trip was so inadequate it almost put me off posting a link to my: 1st great exploration story! 
I play a little and often so was out for 3 months. A tl;dr summary:
Shinrarta Dezhra to Elephant's Trunk Nebular with some diversions
Cobra MkIII
About 6000ly round trip
Travelled exclusively by economical jumps because of my tiny fuel scoop
About 800+ system scans and 3000+ detailed scans
24 million credits
from 64% Scout to 15% Ranger
It was fun but glad (at the moment) to be back. After a little break I think I'll be doing some trading, missions and possibly a bit of power play for a bit.
