NGC 1514 - Planetary Nebula.

NGC 1514 is quite a nice planetary, it's bright, mag. 10.9, has a clearly obvious central star, mag. 9.4

and it's big too, for a planetary, over 2' x 2'.

Also, interesting because NGC 1514 is a very dim nebula characterized by a very

dim, smooth outer shell with a much brighter inner shell and bright blobs.

Measurements of the gas near center indicate that it is expanding outwardly at

25 kilometers per second. The morphology of this nebula is currently thought to

be determined by a binary star (instead of a single star) in the center. Indeed,

based on the likely masses of the progenitor stars (and possible separation)

astronomers estimate these stars would orbit each other with a period of 4 to 9

days. If there are two stars at the heart of this nebula- the more massive one,

which eventually shed its outer envelope, was probably 3-4 times as massive as

our Sun (courtesy of NOAO website)

Well, I got 20 x 120sec exposures and 10 x 180sec exposures before clouds blighted the session.

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.
