In 2007, I noticed that
all of the constellation lines in Google Sky are
the same as those on the SFA Star Charts.
I'm glad to see those constellation patterns in Google Sky.
I spend months researching what constellation patterns had
been used by others and I selected the ones that I liked best.
I started working on the charts in 1998 and worked on them during spare time until
I finally finished them in 2002. One reason that it took me so long is
that I hand picked each constellation line for all 88 constellations.
The constellation pattern that I was never happy with
in any of the books that I used was that of Bootes. Sure it's the "midnight kite" but
Bootes is supposed to be a herdsman or shepherd. Bootes
on our charts was unique to the SFA Star Charts
because it is a modification that I came up with. I tried to make Bootes
look more like Orion. I wanted it to look like
a shepherd holding a staff (see above). So that staff is how I tell
if someone used my data set.
The Google Sky team used the constellation lines that I have freely available here in Excel format:
Here's an article that I submitted to Sky & Telescope magazine in 2002:
The charts are pretty popular with 321,000+ downloads.
Bootes is just one example. All 88 constellations are the same in Google Sky as found on the SFA Star Charts.
