There are so many beautiful patterns which makes it hard "to have them all". Just to make a point: Here is one pattern (in the constellation Taurus, inside the Hyades) which I found on my own which is not inside the SAC-list:
Isn't that a beauty? It looks either like the witch-house from Hansel and Gretel or - if you turn your head 45° to the left) like a butterfly. Later I heard that it is known as "mirror moth asterism".
Every time I'm stargazing 10x50 I find new ones. I guess it will be very difficult to come up with a comprehensive list. Next problem will be naming: "Pretzel asterism?? Naw! That looks like a necklace!"
