Hyperspace travel times

While generally determined by the distance between two planets, hyperspace travel times between two locations seemingly close to one another could be drastically extended by the need to navigate around stellar hazards, such as asteroid fields and nebulae.

An example of this is the journey from Coruscant and Alderaan. In terms of distance, Alderaan was very near to Coruscant. However, it required 16 hours of travel to reach Alderaan due to a section of the route crossing through a part of the largely-uncharted Deep Core which is star-choked and therefore more difficult to navigate in due to its many gravity wells.[2] Ironically, then, it was actually faster to get from Tatooine to Alderaan on the other side of the galaxy.

Pages 206 & 207 (Travel Time): A typical journey between two regions of the galaxy (or between two systems within the same region) takes a certain number of hours. This base travel time can be modified by as many as three factors, each of which is discussed below:

         Hyperdrive Quality: The base travel time given on the table assumes the use of a standard hyperdrive with a x1 multiplier. Faster hyperdrives (x0.5, for example) reduce the travel time accordingly, and slower hyperdrives (x2 or x5, for example) increase travel time.

         Location of Destination: If the destination of the journey is in the same region as the starting point, or if the destination is in the same quadrant of the galaxy as the starting point, the travel time is halved. (the book has a map on pages 208 and 209 in which you can divide the galaxy in four quadrants: two perpendicular lines cut through the center of the Deep Core, dividing the galaxy into four sections, or quadrants - Eddie). Travel time is cut in half for any journey from one place to another place in the same quadrant, even if the two locations are in different regions.

Another Method

The first thing you need to do is get a printed picture of the galaxy of your own. Once you have that you need to take a ruler and measure the galaxy from one side to the other (most likely your picture will be an oval rather than a circle so measure the long ends). Write down the exact inches on a piece of paper (we'll call this number X).

Here is the formula for lightyears to inches: 120,000 / X.

Now that you have that you can use the ruler to determine the distance between one planet and another and convert it back to lightyears.

A x1 hyperdrive goes at about 100,000,000 times the speed of light which means it can cover about 11,415 lightyears in an hour. Just divide the number of lightyears from point a to b by that number and you will get the x1 time it should take.

However, hyperspace is never that easy. The closer you get to the core, the longer it will take in order to avoid the increasing gravity from more densely packed star clusters. In order to emulate this best, divide up the time spent in each part of the galaxy (outer rim, mid rim, core, etc) and multiply the time on the average of the following chart.

Outer Rim: x1
Mid Rim: x1.1
Expansion: x1.25
Inner Rim: x1.5
Colonies: x2
Core: x3
Deep Core: x5

To take the average just add these numbers for every inch you spend in the section and divide by the total distance. Make sure to take into account your hyperspace modifier after this.

Finally, the astrogation check can be modified to either get you there faster or slower. You can divide the time taken by Y by taking a (-5*Y) penalty or multiply it by Z to get a (+5*Z) Bonus.

Based on the proportions of the galaxy, I think getting from the galaxy to one of the two dwarf galaxies is about 50,000 Lightyears and they seem to be about 30,000 and 50,000 lightyears wide each (Riche Maze is the bigger of the two). So you could easily make, or convert from the normal galaxy, a basic hyperspace map for those two as well.
