Sign up to the Uni’s campus in Solitude. Then warp around in something like:
2 x gas harv
probe launcher 8 loaded (8 cargo)
In hi-sec gas sites there are no NPCs that attack you. And there are no rigs which help gas harvesting. Although a couple of Small Gravity Capacitor Upgrade I’s will boost your scanning strength.
it’s a high-sec island. not a great market to generate income for the activity
for more risk and less isolation, you can wormhole ninja. the venture will not really last against the sleepers - so you are restricted in a duration before you need to bug-out when they spawn. (not to mention risk from skilled players attempting to kill you). But a venture is a cheap investment against the decent rewards that can come from even a small amount of some of the gases WH have.
You could also try Hulf Constellation. Which is another hi-sec island and a lot more accessible. (one or two low-secs to cross). I have usually only ever located gas in hi-sec on the islands.
