  " The Andromeda Group, which includes M31, M32 and M110 (all visible in the above image) are very well imaged by astro-imagers and a bit like the Moon easy to overlook. Indeed, you will find a number of our images of the Andromeda Galaxy on the JPO blog.

Whilst we were under the stars the other night, Kurt remembered that we hadn't used the Seestar S30 to capture data from this group of galaxies. It was also a very good time to image the group with the constellations Andromeda and Pegasus riding high in our southern sky. In all we captured 150 x 60 second subs, which were stacked by the Seestar's on board firmware. Pip Stakkert has spent much of the day processing this stack using Affinity Photo, GraXpert, StarnetGUI and ImagePlus6.5.

We were all a bit amazed at how well the Seestar S30 performed on this target" - Joel Cairo CEO of the Jodrell Plank Observatory.

"The Andromeda Galaxy Group—dominated by the spiral giant M31 and its two bright satellite galaxies, M32 and M110—offers a vivid look into the dynamics of galactic evolution within our Local Group. M31, located about 2.5 million light-years away, is the nearest major spiral galaxy to the Milky Way and is on a slow, gravitationally driven collision course with us. Its tightly wound arms, rich with star-forming regions and dust lanes, contrast with the compact, smooth profile of M32, a dwarf elliptical galaxy shaped by tidal interactions with its parent. On the opposite side lies M110, a larger dwarf elliptical whose diffuse structure and signs of past star formation hint at a more complex history. Together, these three galaxies capture a snapshot of the hierarchical processes—accretion, tidal shaping, and galactic interaction—that define the cosmic evolution of galaxy groups across the universe". - Karl Segin outreach officer at the JPO.
