good seeing, bad transparency

Good Seeing is needed to bring out the detailed structure of this often overlooked 50 arc
sec sized planetary nebula. The central star is a blue Pre-White Dwarf that could be
variable. Fortunately the air was very stable that night so we could get a nice image of
this fine PN. Only thing that sucks is that there is nearly no color variation across the
planetary that would make it even nicer. |
