Egg Nebula (PN G080.1-06.5)

Acquisition type: Lucky imaging

I had a night of quite good seeing a few days back, so I took the opportunity to capture some image data on the Egg Nebula. Terminated by clouds, of course, so I only got 24 minutes of data in 3 eight minute live stacks, each of which was composed of 480 half second subs. Since this object is actually quite bright, I used short exposures to capture the best moments of seeing. I should have popped a 2x Barlow in to take advantage of the seeing, but there just wasn't time enough to fuss with it with clouds approaching my area.

I have included a 200% scale inset with an effective resolution of 0.25 arc seconds per pixel as there is lots of detail that becomes more apparent with scaling.

I actually did capture another set of 5 eight minute images a few nights later, but the FWHM of stars in those images were more like 2.25 arc seconds instead of the 1.7 arc seconds FWHM stars in the 3 earlier images I stacked for this image. Unfortunately, it just wasn't worth adding this additional poorer quality data.

That intensely red star in the upper right corner of the image is 2MASS J21014176+3636591 (or WISE J210141.75+363659.1, pick your catalog) is listed as SIMBAD as a long period variable. Based on this and its color, its probably a red giant, rather than a carbon star.

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.
