Prologue
One of the optional waypoints, on an expedition I'll be joining soon, is "Altum Sagittarii Prime" (Quemeou YE-A E0). This sits some 2,870 Ly directly "above" Sagittarius A*, offering a rather unique view of the Milky Way galaxy.
I wanna do it, but I'm having a hard time nailing down the exact requirements for reaching that system. "Altum Sagittari" (Nyuena JS-B D342) is a good bit closer Sagittarius A*, and I'm told that requires a minimum range of 33 Ly (or FSD boosts to compensate) to reach.
But, for "Prime", all I've really been told is "bring jumponium".
Without knowing exactly how far I'll need to be able to jump, or how many long-distance (>33 Ly) jumps I'll need to make, there's no way to know whether I'll even need to use FSD boosts – or, if I do, how many supplies I need to bring with me for them.
Can anyone who's been there (or perhaps happens to be in range of it now) confirm what the minimum requirements would be for a trip to Altum Sagittarii Prime?
To make this relatively simple, let's assume I have a ship that can make it to Altum Sagittarii (i.e.: I have at least a 33 Ly jump range). And, since we already know the mission requirements for Altum Sagittarii, let's use that as the starting point.
Answer Requirements
What I need to know is:
- Minimum number of jumps required, to reach Altum Sagittarii Prime from Altum Sagittarii, which necessarily exceed the mission requirements (33 Ly range) for the trip to Altum Sagittarii.
- Minimum distance for each of those jumps.
- Other obstacles which may affect ship build/supply requirements or route planning for this portion of the trip. (e.g.: Parts of the route without main-sequence stars for refueling. Anything else I've forgotten.)
Best Answer
So, I've finally made it up to Altum Sagittarii Prime and back. The route provided to me by CMDR Alot, generated using EDTS, is now confirmed to work.
Alternative routes may still be viable, with different jumponium and/or jump range requirements. However, the limited availability of scoopable stars at the far end of this trip should also be taken into consideration.
These probably aren't the barest-minimum requirements. But if you get to Altum Sagittarii prepared as I describe below, you shouldn't have any trouble making it to Prime and back.
Here's some more general information, on what to expect in the round-trip if you're flying with the above configuration.
One-way route detail:
Note: The single-jump distance between Quemeou YE-A e7 (jump 34 on the list) and Altum Sagittarii Prime is only 81.71 Ly. So, a ship with a 41 Ly jump range could make the round trip with just two Premium injections. This also saves the worry of going through so many jumps without an opportunity to refuel.
