Bubbly (Oyster) Planetary Nebula NGC1501

Acquisition type: Lucky imaging

NGC1501 is a complex bipolar planetary nebula in Camelopardalis, more commonly known as the Oyster nebula, with the progenitor star as the pearl in the oyster. In Hubble Space Telescope images it is referred to as the Bubbly Nebula, which I think is a better description for how it looks in a photographic image. The central star is a carbon-rich Wolf–Rayet star, which means the star has surface enhancement of heavy elements, a depletion of hydrogen, as well as strong stellar winds. Also, at spectral class WC4 the star is extremely hot, something like 120,000 K. It is also a variable star, varying brightness periodically and dramatically over one-half hour, though at maximum it is only 14.4 magnitude. It may actually be a binary system as well.

I had actually hoped to get more time on this target, there is more faint nebulosity around the core, but horrible skies for most of November, December and much of January really limited my time. And now sadly, it is blocked from view. Maybe next year...

Title: Comparison to Hubble Space Telescope Image

Description: Be patient for the gif animation to run, it can be slow to start the animation.

The Hubble Space Telescope Image was rotated and resized for the comparison to my image in this gif. Note that the HST image is quoted as being in arbitrary colors. For example, the central star is a hot blue white star, not a cool red star as shown in the HST image. I was really please with the details I was able to bring out, and the nice correspondence to the fine HST details.

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.
