M2-53

Acquisition type: Lucky imaging

This is a small planetary (17 arc seconds across) is fairly dim at around 14.8 magnitude (V). The central star is faint at around magnitude 20, and is hard to pick out from the nebula background, but showed up once I sharpened it enough. The Gaia mission database has photometric data on the central star, but does not have parallax data (maybe due to interference from the bright surrounding nebula), so there is no good distance estimate. Based on the angular size of the nebula and assuming a size of 1.1 light years across, that would put its distance at roughly around 13,000 light years. This would put the absolute magnitude of the central star at around 7.8, consistent with a dimming dead star that has almost settled into its final white dwarf stage.

Duoband and IR/UV Cut data was combined for the nebula, while the IRCut data was used for the stars. Live-stacked luck imaging exposures were 3 seconds for the duoband images, and 5 seconds for IR/UV Cut images. Live stacking was performed in SharpCap.

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.
