Re: (IAAC) Obj: NGC 6888



  G'day Mark and everybody else
 I thought that you might like to look up an article in the Astrophysical Journal Supplement Series 53:937-944
DEC 1983
The article is called Galactic Ring Nebulae Associated With Wolf-Rayet Stars. This article contains a list of
some nebulae
and finder charts to help locate them. These nebulae are wonderful to look at.
Some of the southern observers may like to try the star HD148937 with its associated nebulae NGC6164/5.
This star has a nebulae shaped like a barred spiral about it. The star appears to be pre main sequence and may
have an age less than 350,000 years. (The astrophysical Journal 251: 126-132 DEC 1981)  The finder chart
associated with the article is over exposed. It does show the spiral nature of the nebulae. Of particular
interest is the unusual loops of nebula found about 7' north east of the main object. Through Hector this
nebula is VERY faint. It appears as an arc of nebulae about 10' long orrientated almost north-south. This is a
great object but due to its position at -40 deg it will be very difficult to see from the continental US.
