Planetary Nebula Vy1-1 (PN G118.0-08.6)

Acquisition type: Lucky imaging

Some vital statistics on this small bright planetary nebula, with good distance data from Gaia mission parallax measurements:

Vy1-1 (PN G118.0-08.6)
Size: 11 x 11 arcsec (0.9 ly across)
Magnitude: 12.60(V)
Distance: 16,616 ly
Abs Mag=-0.94

The central star is also very bright for its distance:

Gaia DR3 419326659360627968
Magnitude: 14.16(V)
Distance: 16,616 ly
Abs Mag=0.63

A star that has approached white dwarf stage would have an absolute magnitude of a much dimmer 10th magnitude. Since the nebula is small (0.9 light years across), this points to the nebula being pretty young, as an older nebula would be larger than 1.5 light years. The central star might be a binary, making it a lot brighter than just a lone white dwarf, or the Gaia magnitude data for the star might be muddled by the brightness of the surrounding nebula.

I combined IR/UV Cut and duoband (a OIII/Ha/Hb triband filter) filter data for the nebula and the star colors just from the IR/UV cut filter data. The images were live-stacked IRCut data was collected using 4 second live-stacked subs while duoband data was collected using live-stacked 3 second subs.

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.
