| Image | Details |
 | John Hughes, 25 January 2021. William Optics Z103 refractor with ZWO ASI1600mm Pro cooled mono camera on SkyWatcher EQ6R-Pro mount.

The four galaxies are respectively at approximate distances from Earth: 23m LY, 35m LY, 61m LY and 63m LY. During imaging, the Moon was 89% illuminated which resulted in a large gradient on the left hand side of the image, especially in the red channel, but this was easily removed with PixInsight's DynamicBackgroundExtraction tool. The images is based on 3 minute exposures, with RGB subframes in the ratio 20:31:36. |

| Image | Details |
 | David Murton, 28 August 2017. NGC7331 and the nearby group of four galaxies known as the Deer Lick Group. Further away, to the bottom right, is Stephan's Quintet, a group of five interacting galaxies. The Quintet is only 4 arcminutes in diameter. Close-ups: NGC7331, Stephan's Quintet. Skywatcher 190 mm Maksutov-Newtonian on NEQ6 mount. Canon 60Da camera. Fifteen 360 s exposures at ISO 800. |
 | David Murton, 06 September 2015. NGC7331. Skywatcher 200PDS 200 mm f/5 Newtonian on NEQ6 mount. Canon 1100D camera. Stack of seven 360 s exposures at ISO 200 with dark frames and flat frames. The galaxy shines at magnitude 9.5, and lies at a distance of 49 million LY. |
NGC7332 and NGC7339 (Pegasus)
| Image | Details |
 | David Murton, 06 September 2015. Skywatcher 200PDS 200 mm f/5 Newtonian on NEQ6 mount. Canon 1100D camera. Stack of five 360 s exposures at ISO 400 with dark frames and flat frames. The galaxy shines at magnitude 11.1, and lies at a distance of 67 million LY. |
Abell 426 (The Perseus Cluster)
| Image | Details |
 | David Murton, 21 January 2017. Skywatcher 200PDS 200 mm f/5 Newtonian on NEQ6 mount. Canon 60Da camera. Stack of ten 480 s exposures at ISO 400. The cluster is one of the largest objects in the universe: it is a group if over 1000 galaxies roughly 250 million LY distant. The larger bright galaxy to the left of the image is NGC1275, a prodigious source of X-rays and radio emission. The image is 1.2° wide, approximately 15 million light years. Image with main galaxies marked, upwards of 130! |
