It glows strongly in hydrogen‑alpha, threaded with dark dust lanes and sculpted pillars shaped by the radiation and winds of massive young stars. Embedded open clusters light up the nebulosity; the Index Catalogue designation IC 1848 historically refers to the stellar association within this region.</p> <p>From mid‑northern latitudes the Soul rises high in the autumn and winter sky, making October evenings a convenient time to image it. Visually it is a challenging, low‑contrast target requiring dark skies; narrowband or broadband UHC filters help bring out the emission. The field here fits well within an APS‑C sensor at 750 mm focal length, framing the brighter central structures along with surrounding filaments.</p> <p><img class="gallery-image" data-flex-basis="357px" data-flex-grow="148" data-title-escaped="IC 1848 — Soul Nebula (annotated)" height="1605" loading="lazy" sizes="(max-width: 767px) calc(100vw - 30px), (max-width: 1023px) 700px, (max-width: 1279px) 950px, 1232px" src="https://astro.t3k.pl/post/2025/10/ic1848_soul_nebula/images/annotated_ic1848.png" srcset="https://astro.t3k.pl/post/2025/10/ic1848_soul_nebula/images/annotated_ic1848_hu_afd0ce8ea1a57095.png 800w, https://astro.t3k.pl/post/2025/10/ic1848_soul_nebula/images/annotated_ic1848_hu_2be6c8a5ea4ffa4b.png 1600w, https://astro.t3k.pl/post/2025/10/ic1848_soul_nebula/images/annotated_ic1848.png 2391w" title="IC 1848 — Soul Nebula (annotated)" width="2391"></p> <table> <thead> <tr> <th></th> <th></th> </tr> </thead> <tbody> <tr> <td>Telescope</td> <td>SkyWatcher 150/750P</td> </tr> <tr> <td>Mount</td> <td>motorised EQ3-2</td> </tr> <tr> <td>Camera</td> <td>Canon 600D (astro‑mod)</td> </tr> <tr> <td>Filters</td> <td>Astronomik UHC 2&quot;</td> </tr> <tr> <td>Exposure</td> <td>59 × 120s (1h 58min)</td> </tr> <tr> <td>Bortle</td> <td>5</td> </tr> <tr> <td>Moon</td> <td>Waxing gibbous (84.4%)</td> </tr> <tr> <td>Processing</td> <td>Siril, Prism Deep, CosmicClarity, Gimp</td> </tr> </tbody> </table>
