Abell 41 (Gary Imm)

Celestial hemisphere: Southern · Constellation: Serpens (Ser) · Contains: PK009+10.1

Abell 41

This small Abell PN, also known as PK9+10.1, is located 15,000 light years away in the constellation of Serpens at a declination of -15 degrees. It is a magnitude 16 elliptical PN which spans 24 arc-seconds in our apparent view. This corresponds to the typical PN diameter of 2 light years.

In apparent size, this is the smallest Abell PN. Not coincidentally, it is also one of the furthest away from us.

The peak HII signal strength here is about twice that of the peak OIII strength. As usual, the HII is dominant along the rim. The binary blue progenitor star at the center is clearly visible. The binary progenitor results in the elliptical PN type.

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.
