NGC 3242 Ghost of Jupiter Nebula -- SII & H-beta

Cataloged as NGC 3242, the Ghost of Jupiter is so named because of its resemblance to the shape of the planet Jupiter, at least when looking at visually through a telescope. It's a planetary nebula located in southerly portion of the sky-spanning constellation Hydra, and is about 4,800 lightyears away. Planetary nebulae, despite their name, have nothing to do with planets; they're the result of dying main-sequence stars that can no longer hold onto their outer layers of gas. Our own Sun will eventually meet this fate.

This image was shot using the new Antlia APT-L SII & H-beta filter I'm testing. H-beta is the source of the rich turquoise here; there is basically no red-glowing sulfur here at all (or at least, it's so dominated by the hydrogen as to not show up). I also imaged this with the Optolong L-Ultimate (so H-alpha and OIII), which I plan to combine with this image and do some color mapping. We'll see what comes out!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
