Thanks, Mike.

BTW, Sakib Rasool pointed out to me that I also captured the nebulosity around the hypergiant luminous blue variable star P Cygni that is discussed in this paper: http://www.aanda.org/articles/aa/pdf.../aa6039-06.pdf

P Cygni has a brightness of 4.8 now but at the end of the 16th century it was unknown until it suddenly brightened to mag 3. The paper mentioned above suggests that the filamentary nebulosity and giant lobes around the star were created by its earlier shenanigans.

Interesting that the results from 9 hours on a 106mm scope compare well to 40 minutes on their 1.3m Ritchey-Cretien

The attached crop shows the Soap Bubble clearly on the right and the knot of nebulosity around P Cygni (the brightest star) on the left.
