Dear Chris,

     With all the appropriate praise heaped on this image of IC410, I'm a
tad reluctant to ask about the asymmetrical blue halations around four of
the brighter stars:  three above and one below the nebula.  Where did they
come from?  Given their identical shapes, these cannot be reflection
nebulae.
