Abell 43

This object is a faint planetary nebula located 5000 light years away in the constellation of Ophiuchus, at a declination of +10 degrees. Its apparent size to us of 1.3 arc-minutes corresponds to a true diameter of about 2 light years. The white dwarf is plainly visible in the center of the nebula. The OIII signal is much stronger than Ha for this nebula.

Planetary nebulae are like snowflakes, all different in their exact structure. But it is interesting to me that Abell 43 has a similar structure and composition to that of other PN I have imaged. I have attached a comparison image of 4 PN which shows the similar OIII filamentary arcing structures which weave through each of these objects.

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.
