Pacman Nebula NGC 281 in Cassiopeia imaged from an urban location

Overview

A wide-field view of one of the richest star-forming regions in the northern sky, captured from Bortle 8 city skies using narrowband techniques but with an OSC camera.

Background

The Heart and Soul Nebulae are popular targets for astrophotographers. They appear relatively large and are well-placed in the sky for observers in the northern hemisphere. They’re also relatively bright, which is definitely a bonus for urban astrophotophotographers having to battle light pollution!

This is my first full imaging project using my new Svbony SV535 telescope. It has a focal length of 105mm, which is extremely wide. In fact, the main image is a crop of about a quarter of the full picture! The Svbony SV535 is also fast at f/2.8, so I was able to collect data using three filters (Optolong L-Quad Enhance, Optolong L-Ultimate, Askar E2) to create an SHO image using an OSC camera in just two nights. This is very speedy considering my city centre location.

Close-ups

  • The Heart Nebula, IC 1805
  • The Soul Nebula, IC 1848
  • The Bear Claw Nebula (Sh2-200)
  • The Double Cluster (NGC 869 & NGC 884)

Science

This region is part of a vast star-forming complex within the Perseus Arm of the Milky Way. The Heart and Soul Nebulae, along with the Double Cluster, all originated from the same giant molecular cloud, making this field a rare combination of active star formation and young stellar populations in a single frame.

The Heart Nebula (IC 1805)

This is a sprawling emission nebula. Its glow is mostly caused a central cluster of young stars, only a few million years old. They’re emitting ultraviolet radiation, which is ionizing the surrounding gas.

The Soul Nebula (IC 1848)

This is part of the same stellar complex as its neighbour, the Heart Nebula. Pockets of denser gas are collapsing in on themselves, triggering new stars to form.

The Bear Claw Nebula (Sh2-200)

A very different kind of object to the Heart and Soul Nebulae, the Bear Claw is actually a planetary nebula; the remains of a low-mass star that’s reaching the end of its life. The star’s outer layers are drifting off into space, creating the bubble that I managed to photograph. Its distinctive blue-green colour comes from doubly ionised oxygen, making it stand out against the hydrogen-rich emission of the Heart and Soul Nebulae.

The Double Cluster (NGC 869 & NGC 884)

This pair of clusters contain hundreds of stars, and probably all formed together from the same nebula around 14 million years ago.

Here are images of objects contained within my Svbony SV535 image. These were all imaged using my Askar 130PHQ, which has a much longer focal length of 1000mm. Click on each image to visit that target’s page.
