Bubble Nebula

[Rodd]

Here is a rarity--an image I am satisfied with for what it's worth (a long and tortuous path).  The problem is, the "for what it's worth" part of the sentence.  Let me explain: The Ha of this image was taken at a focal length of 1,960 mm using a C11Edge and ASI 1600 camera.  I always use Ha as a luminance layer in my SHO palettes (A lightness layer in PI I think, which is different than luminance).  But in general, the L caries the detail in narrowband images (except on rare occasions when OIII is greater, like with Thor's Helmet, or in OIII portions of the Veil). The native resolution of the system reduced by .7x is .4" and bin 2 is .8" (.78 according to Astrobin).  While not a displeasing rendering, I am a bit underwhelmed for the focal length and aperture.  I guess a better choice in my sky is a resolution of 1.5-2, which shouldn't be surprising, I guess.

Here's the bubble taken with a 5" refractor.  The scale is much smakller--but at full resolution, are more details are visible?
