OPM and transfer window planners?

[strider3]

I am searching for a tw planner that will work with OPM in KSP 1.12. I am nearing the end of my stock Kerbol system exploration and am looking to expand my horizons while waiting for KSP2. A search of the OPM, Astrogator, etc. forums hasn't resulted in a clear answer.

Anyone have any ideas?

I think either Kerbal Alarm Clock or Astrogator should be fine.

I've used both mods with KSP 1.12.3 and non-OPM planet packs. I've also used both mods with OPM in earlier KSP versions. I've never tried 1.12 with OPM at the same time, though.

Expect transfer time estimates to sometimes be a little inaccurate. I deal with this by launching into an LKO parking orbit a week early, then finetune interplanetary transfer times from orbit. If you play with life support or fuel boiloff mods then you might need to adjust this strategy.

Thanks. The one...feature...of TWP that I like is the ability to pick a transfer window with a higher D/V requirement, if desired. I've never used KAC, I did not realize it could plan a transfer. I'll check that one out, as well.

Another thought I just had is using MechJeb. I've never used it for that type of planning and not sure it will do that?

Thanks for the ideas.

Yes, Astrogator is designed to work with arbitrary planet packs. Here's the response where a user confirmed success with OPM and a few others:
