Position: RA 16:01  DEC -35:
Description:
Without OIII filter at 342x, NGC 6026 appears as a fairly faint ghostly glow 
around a bright 13.3mag central star. The CS almost disappears when using the 
OIII filter, the nebula does stand out a little bit better but, it still is 
faint. Now with the use of the OIII, some very feeble details are visible: A 
brighter 10" spot appears SE of the CS with averted vision. The center of the 
planetary now seems slightly darker but, that might be a visual effect due to 
the central star shining in it. NGC 6026 also appears slightly elongated E-W 
and looks mottled all over. The edge of the nebula does not appear sharp but, 
it is gradually fainting away.  A bright 7.5mag, orange star is located 7' SE 
of the nebula.
