First, your pictures are very large and they delete them if you don't resize them. I know it's a pain.
I have been told that cracks running length wise on a bow are nothing to be too worried about. But see what the others have to say.
Bona Nice bow btw!
I'd fill it with super glue and shoot it. Keep a watch to be sure it doesn't enlarge but you should be OK.
When I fill a large crack with superglue I tap the side of the limb with a piece of scrap wood to get the air bubbles out and get the glue deeper in the crack.
I like to heat up the area with my heat gun and then let the CA fill in.
Eric, tap the sides? could you explain?

Nick, tapping the sides would release any air bubbles attached inside the check.
