Bob,
According to what I see and read on the WEB, it is supposed to be blue. I
don't know if it is related to the temperature or the surrounding gas giving
it a blue tint.

Nice pic Bernard. I know that white dwarfs are hot, hot, especially during
the time that they're still surrounded by visible PNs. So is the blue color
from the temp of the star or is it an artifact of the imaging process?

Hi,
The link below is to Jones-Emberson 1(PK 164 +31.1). This is a planetary
nebula in the constellation Lynx. I had never heard of this nebula before
about two months ago and decided to give it a try. It reminds me a little of
the Dumbbell nebula. I remember someone referring to it as the Headphone
nebula, but I can't remember who. The very blue magnitude 16.8 White Dwarf
star is very visible in the center of the nebula. Comments and suggestions
welcomed.

Thanks,
