Day 4 of the monsoon "cloud out" over Tucson. As much as I would like to complain that it keeps me inside at night, these afternoon storms provide a majority of our annual rainfall. I was going through my endless sub files and found this jpg of M27 which I forgot to post. I processed it 2 months ago on a plane to Cleveland. Once I got to Ohio, being with family was so nice that must have let this image slip from my mind. I wont bother with the details of this planetary nebula as I am sure you are all plenty familiar with it. Once again, thanks for your comments, suggestions, and support. This community and the relationships built through it is just as much of a part of why I do this as the photos we share. Thanks for stopping by.
