NGC3572 nebula and NGC3532

Description and Details: Imaging was done through Hydrogen II, Oxygen III, and Red, Green and Blue filters, with a Zwo ASI 2600MM camera and an Astro-Physics AP130 mounted on an Astro-Physics Mach1 mount.

Nebulae are rendered as an HOO image and the stars retrieved from the RGB image.
Processing done with Pixinsight.
On the left side of the image is NGC3572, a young star-forming region in the constellation Carina, about 9,000 light-years away.

On the right side of the image is NGC 3532, a rich open star cluster, also in the constellation Carina, but much closer at around 1,300 light-years away.

Several planetary nebulae shine as blue bubbles in the image, particularly PHR1107-5855 and PHR107-5857.

They are Sun-like stars in the final stage of their evolution. Their outer layers have been expelled into space, while the hot central remnant ionises the surrounding gas, causing it to glow.

These objects have very low surface brightness, making them difficult to detect and typically requiring deep narrowband imaging (Hα, OIII) to reveal their structure.
