Abell 49 and Vy 1-4 (Gary Imm)

Celestial hemisphere: Southern · Constellation: Scutum (Sct) · Contains: PK027-03.1 · PK027-03.2

Abell 49 and Vy 1-4

These 2 faint planetary nebulae are located in the constellation of Scutum at a declination of -6 degrees.

Abell 49, at the center of the image, is a magnitude 16 PN which spans 1 arc-minute in our apparent view. I could not find a distance for this object. Assuming that this object has the typical PN diameter of 2 light years, it would be located about 7000 light years away from us. HII dominates the nebula rim while OIII dominates the nebula central region. Some breakout seems to appear at the 11 o’clock and 5 0’clock positions. I do not see a progenitor star.

Py 1-4 is the beautiful tiny teal-colored object located towards the left side of the image. Even though this is a much smaller PN than Abell 49, it is a brighter magnitude (14) because the light is more concentrated. This PN is located 33,000 light years away, which is very distant for a PN. It is 1.3 light years in diameter.

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.
