Description

I've always wanted to image a glob and what better to start with than M13, right?—at least from my northern latitude (37°). I wasn’t sure what changes to make with my usual processing steps but am pleased with the overall result: stars in the cluster and the colors.

I’ve read about the ‘propeller’ dark structure in M13. I’ve tried a few times finding it with my 10” Dob but could never confirm seeing it. I was hoping it would be obvious in my image and now concerned I’ve processed it out . I note a structure akin to the Mercedes logo at ~ 6 o’clock about a third to half way from the center (to edge). Perhaps that's the one? Can someone confirm?

Feedback welcome. Thanks for looking.
