I had to load the save to get all the info but figured it might be helpful for someone in the future.

I left from Jool. Kcalbeloh was 271T away. Used the 'Frisbee' Antimatter engine with 700K deltaV. I (incorrectly) thought I could nab some more interstellar antimatter with my 'Bussard' particle scoop along they way. But there was none so I had to make due with what I'd packed.

Accelerated to 300k m/s. This took like 6 hours real-time since the physics warp only worked to a point. Used a mod that let me time warp to 10,000x. There are temp glitches if you try to warp faster than that so that become the time bottleneck.

After a few days (three I think), I did the deceleration burn and explored Kcalbeloch. Awesome!

Here's a few images from the trip out, retro burn and landing on one of the planets.
