I'm just compiling the dumps and planet screenshots that /vg/ has been posting. I haven't been to these planets and only know as much as people post about.  I know the format is bad, but I've been compiling this since the first Starbound thread. Hopefully someone who visits all of them or the original co-ordinate posters can fill in the holes.

I'm on "II a" at the moment. Walking left there's a huge monkey lab with a Dash ability in the basement and going around the planet there's a boss in a Mushroom biome with lots of mushroom tree's.

Avian Tower Temple.  Underground Frog Temple and Rabbit Burial Site under Tower to the SE.
Frog Temple has vendors

Instructions:
From your spawn point, head left to the Avian Tower Temple. From the throne dig straight down and every so often go slightly SOUTH, EASTERN direction (SE) until you come across an ancient Rabbit Burial Site. From there continue going East and then go South again.
Eventually you should come across a HUGE Underground Frog Temple.

To the LEFT of the spawn point you will encounter an anchor, build a stairway/platform/something to go up at this point. You will encounter an avian skyship that sells a variety of 1h and 2h guns. This makes life in the Alpha Sector (and the boss) MUCH easier.
