⟨ballatik⟩ Optimizer worked well for a few lunar transfers tonight. Didn't seem to end up with drastically better maneuvers than I could have by hand, but it did all the fiddly part for me which was nice. The only issue I had was that it stuck to the initial engine selection. If I tried to switch to RCS, or staged and rebased, and then hit optimize it switched back to the previous engine.

⟨makoivis⟩ Is it still windows only?
<queqiao->
⟨sichelgaita⟩ Yes, Windows only. Building a release for the other platforms is rather time-consuming for us.
<queqiao->
⟨makoivis⟩ Gotcha. So those are only the release builds then?
<queqiao->
⟨makoivis⟩ * So Mac builds are only at release?
<queqiao->
⟨sichelgaita⟩ Yes.
<queqiao->
⟨makoivis⟩ I'll install it on a windows computer and give it a spin later today
<queqiao->
⟨butcher6994⟩ Sometimes, if the mood takes them.

⟨scimas⟩ Nothing "wrong" probably, except being a bit impatient. Ballistic captures are very sensitive to the tiniest changes to the initial state as you have discovered. You need to just spend time tweaking the manoeuvre time and tangent velocity back and forth by very small amounts until you get the desired capture. And after you have successfully plotted the manoeuvre, expect similar challenges when executing it too. Either be prepared to...
<queqiao->
... limit your engine thrust to 10% or less - maybe even 1%, or better carry RCS for fine tuning.
<queqiao->
Also, changing the manoeuvre frame to KCI might help a little.
<queqiao->
⟨rnlahaye⟩ I can make a Mac build if you want
<queqiao->
⟨partypaddi⟩ Thank you for the reassuring message 😄
<queqiao->
I'll try again soon and now that I know I'm not doing anything "wrong" I think I'll manage to stay more patient as well

⟨makoivis⟩ I would test that immediately
<queqiao->
⟨egg⟩ No thoughts whatsoever at this time, aside from the fact that it seems that this is in their definition; I am very jetlagged (and probably very busy this week because Unicode Technical Committee)

⟨makoivis⟩ re; the optimizer - if I want to optimize a transfer to moon orbit, does my flight plan need to contain both the initial TLI and the capture burn, or just the TLI?
