If you already are East of Sagittarius A* you don't need to cross the Abyss, but you can climb the Carina Sagittarius Arm. Or alternatively you can cross tha gap between the two arms way eastern than the Roncevaux Crossing. This area is called Silentium, and the gap there the Silentium-Centauri Badlands. In the Silentium Centauri Badlands star density is very good for any jumprange, especially near the ecliptical. But near the ecliptical there are few scoopable stars. There's a layer of scoopable stars just above the ecliptical that makes a good route for any spaceship, just be carefull to watch your fuel gauge, since the route plotter can throw you several unscoopables in a row. If that happens just make a jump few LY above to find OBAFGKM. The 2 POIs (Centauri Shores and Silentium Shores) are just Historical, you can start your traverse from everywhere here. I have been the first to document a crossing of Silentium, if you are interested in the details of this area please visit
here.
Once you arrive in the Carina Sagittarius Arm (Silentium - Solitude - The Far Rim) don't head immidiatly north, you will never breach the 65K line here and toss yourself into the fringe where there are few stars. Just stay in the middle untill the meridian and then climb toward the Northern Meridian.
