[Lvas] M-27 and other

[Fred Rayworth]

All,

 

Here is another one where I missed something. I've observed M-27 many many times but concentrated on the dumbbell shape and not too many other details. I remember seeing individual stars within it, but never took note of them. If the night is good and you have decent aperture, you may see flaking at the edges of the nebula along with sevral stars. Maybe even the central star.

All,
 
I was going through my notes regarding M-27, and realized that I had done some pretty extensive work on this object. It was one of the objects in my first and only publication to date. 
 
In 1995 and 1996, I went through The Finest Deep-Sky Objects by James Mullaney and Wallace McCall, Sky Publishing Corporation, with three printings, 1966, 1972, and 1978. This was my first deep-sky reference book many years ago. 
 
I wanted to do extensive visual work and include a more precise and modern update of this excellent book. I ended up spending over 250 hours at the eyepiece and another 50 hours to summarize within a period of less than one year.
 
Tom English helped me to print this book at GWU and I sold over 100 copies, mostly locally. I have included a picture of my front cover. If you will notice it has a picture of M-27, showing a very round, almost bubble like appearance. I used the orginal Mullaney/McCall cover picture on my publication along with some of my notes, etc.  
 
I am thinking about revising this book and self publishing again on a broader scale. 
 
The (+)1 was the Crab Nebula, as Jim Mullaney said that he should have included in their orginal publication in 1966.
 
Mullaney and McCall used the famous Allegheny Observatory, University of Pittsburgh, during their original survey, and the writing of the book.
 
Both astronomers used a variety of telescopes at this facility, but one of particular interest would be the very, very famous 30-inch refractor. Do a little Google research and find out about the stolen lens, and other interesting reading regarding this scope and observatory.
