Description

I started this passion exactly one year ago. My first two targets were M57 and M27. Now that they sky has come full circle I am re-shooting those original images to see how far I've come. Here is my M27 year two first draft. The noticeable difference is that the central core white dwarf star can clearly be seen in this years photo (where as last year I contemplated taking the dodge tool to where I thought it was located in my noisy, low quality first attempt). In addition, this image was taken under a 98% full moon.
