[Lvas] M-13 And Propeller

[roger ivester]

Jim,

 

Re: Your images of M-13 and the propeller. 

 

Very nice...just forwarded to the LV forum. It would appear that we will have quite a few images of M-13 for next months observers challenge.

 

I was also admiring your image of NGC-4631 and N-4627. After observing this pair and NGC-4656 and N-4657, I find that if seeing is not very good, the pair of double stars at the lower right is not visible in my 10-inch. This also applies to the very faint NGC-4627. 

 

Both fit nicely in a 1° FOV @ 57x using my reflector.

The attached file contains two copies of an image of M13 found on my web site (wildwoodpines.org).  The lower image has the propeller brushed in to make it more apparent.  But it does show up quite well in the upper, untouched image.

LVAS all,
 
I have penciled over the "very obvious" dark lanes in Frank Barretts, excellent image of M-13.
