Ghost of Jupiter - NGC 3242

NGC 3242 is a planetary nebula in the constellation of Hydra. NGC 3242 is most frequently called the Ghost of Jupiter, or Jupiter's Ghost due to its similar size to the planet, but it is also sometimes referred to as the Eye Nebula.

This unguided image was captured, in a Queen Creek (Arizona) Bortle 7 backyard, using a Celestron EdgeHD 11" telescope with a 0.7x focal reducer. The telescope is mounted on a 10Micron GM2000 HPS II mount. The camera is a ZWO ASI 2600MC Pro using a Optolong L-Enhance filter. The image is comprised of (only top 50% used) 400 30 second exposure and 185 60 second exposure length frames, captured over 5 nights (2-25-2022 to 3-6-2022). The images were stacked and processed in Pixinsight, and fine-tuning done in Photoshop.

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.
