I follow @Johnny Qiu who recently posted same (image here) captured at Deep Sky West.  I was blown away by his image.  What a fabulous region to image!   At the time I had just started to capture this beauty from my backyard.  We thought how would a B7 backyard image with half the focal length compare?  Oh, Johnny's image later went on to be IOTD!  👏🏻👍🏻    So how did the comparison come out?  In my humble opinion, not too bad...I'm very pleased!  ...and the distant galaxies like NGC7337 at 350MLYs are resolved.  Backyard warriors - we can do this!   

I did have all kinds of trouble saving as JPG from Pixinsight (latest version).  The JPG didn't look anything like the .xisf . check out version B to see.  I know it's not my monitor (5k iMac).  I tried various "save as" with no luck.  I finally just took screen shots from my Mac (command shift 4) to get an image fairly close to my finished processed...that's right this is a screenshot 🤪!   This behavior has never happened to me before...is it the new Pix version causing?  To troubleshoot, I'm going to change back to an older version of Pix...when I get the time. 

worth reading from Wikipedia:  NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40MLYs away in the constellation Pegasus. It was discovered by William Herschel in 1784.NGC 7331 is the brightest galaxy in the field of a visual grouping known as the NGC 7331 Group of galaxies. In fact, the other members of the group, NGC 7335, 7336, 7337 and 7340, lie far in the background at distances of approximately 300-350 million light years.  The galaxy appears similar in size and structure to the Milky Way, and is sometimes referred to as "the Milky Way's twin".However, discoveries in the 2000s regarding the structure of the Milky Way may call this similarity into doubt, particularly because the latter is now believed to be a barred spiral, compared to the unbarred status of NGC 7331.[6] In spiral galaxies the central bulge typically co-rotates with the disk but the bulge in the galaxy NGC 7331 is rotating in the opposite direction to the rest of the disk.  In both visible light and infrared photos of the NGC 7331, the core of the galaxy appears to be slightly off-center, with one side of the disk appearing to extend further away from the core than the opposite side.  Multiple supernova events have been observed in this galaxy.
