IC 3568 - The Lemon Slice Nebula (Bob Stevenson)

IC 3568 - The Lemon Slice Nebula

While imaging this nebula, I had read how it is nearly perfectly spherical and tiny. That is very apparent in my data. Its a perfectly round dot in space - just like a tiny button. Details in the central region are impossible to resolve with my current setup, but the outer portion does have some variation in the OIII and Ha data which I tried to preserve in the final image.

This nebula has two shells. The brighter inner shell is only 6″ in diameter. The outer shell is 18″ across and was easy to capture despite its lower surface brightness. The central star is magnitude 12.3.

The Lemon Slice Nebula is about 4,500 light-years away, with a diameter of 0.4 light-year. It is small compared to other planetary nebulae, but is huge compared to something like our solar system. It is the northern most planetary nebula in the sky at a declination of 82.5 degrees.

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.
