You can make good money from deep space mining, I have been doing it for quite some time, the problem is the remote asteroid bases are part of the bgs like any other station, unfortunately because they are mainly isolated, poor, low population stations, the missions boards are either empty or hardly offer good missions.
Until FD make changes, your best option is to find fringe bubble systems, stock up on well paid missions, then head out into the black for some R&R mining,you'll have a week to finish the missions, so I'll use that time to mine and explore nebulae within a 5000ly radius. Personally not fussed about the cash, so pull in around 50mill from the trip.
Those remote asteroid bases are only useful for outfitting, limpets , repairs, module and ship transfer.
I'd really like the see more extraction and refinery bases out in the black, small bubbles as opposed to isolated stations, this would greatly help with missions appearing on the boards, also well paid long range trucking to those stations, hauling food, meds, beer etc for the workers on those stations.
OP, for a great vista, not too far from the bubble, but remote enough to be left in peace, check out the HYADUM system. A pristine ring extremely close to a giant yellow star. Half to the Pleiades
Thanks i ll check the HYADUM system
