This is my first processing of the data from our new QHY268M and Chroma filters and I am delighted with the clean data and the manner in which it has rendered this wonderful galaxy cluster and background stars. NGC 7331 is a magnificent unbarred spiral galaxy and I have wanted to image it for some time now. What we had perviously framed as a two panel mosaic in the smaller FOV of the QSI690, capturing NGC7331 and Stephan's Quintet, has been captured in a single frame.  There was a smattering of IFN across the frame but I haven't over-stretched the data in an attempt to reveal the faint nebulosity.

From Wikipedia: "NGC 7331, also known as Caldwell 30, is an unbarred spiral galaxy about 40 million light-years (12 Mpc) away in the constellation Pegasus. It was discovered by William Herschel in 1784.[3] 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.[4]The galaxy appears similar in size and structure to the Milky Way, and is sometimes referred to as "the Milky Way's twin".[5] 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.[7] 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. SN 1959D, a Type IIL supernova,[8] was the first supernova identified within NGC 7331.[1] The supernova was discovered by Milton Humason and H. S. Gates in a survey at Palomar Observatory.[9] More recent supernovae are SN 2013bu and SN 2014C, the latter of which underwent an unusual "metamorphosis" from a hydrogen-poor Type Ib to a hydrogen-rich Type IIn over the course of a year . [10] A 1903 photographic plate from Yerkes Observatory shows a magnitude 16.6 candidate transient that may have also been a supernova."

Stephan's Quintet recently featured in a JWT data release to great fanfare, and justly deserved. This attempt hints at the structures and if I win the Lottery I can indulge myself in a large scope to do them justice .  From Wikipedia: "Stephan's Quintet is a visual grouping of five galaxies of which four form the first compact galaxy group ever discovered.[2] The group, visible in the constellation Pegasus, was discovered by Édouard Stephan in 1877 at the Marseille Observatory.[3] The group is the most studied of all the compact galaxy groups.[2]The brightest member of the visual grouping (and the only non-member of the true group) is NGC 7320, which has extensive H II regions, identified as red blobs, where active star formation is occurring. Four of the five galaxies in Stephan's Quintet form a physical association, a true galaxy group, Hickson Compact Group 92, and will likely merge with each other. Radio observations in the early 1970s revealed a filament of emission which lies in inter-galactic space between the galaxies in the group. This same region is also detected in the faint glow of ionized atoms seen in the visible part of the spectrum as a green arc. Space telescopes have provided new insight into the nature of the filament, which is now believed to be a shock-wave in the intergalactic gas, caused by one galaxy (NGC 7318B) falling into the center of the group at several millions of kilometres per hour. Stephan's Quintet was selected as one of the five cosmic objects observed by the James Webb Space Telescope as part of the release of its first official science images."

I have uploaded the full FOV, and two progressively smaller crops along with a tight crop of Stephan's Quintet.
