vdB 98

This Astrobin Debut Object is a faint blue reflection nebula is located 2600 light years away in the constellation of Puppis at a declination of -25 degrees. It spans 11 arc-minutes in our apparent view. This corresponds to a width of 9 light years.

The asymmetric nebula surrounds the 6.8 magnitude bluish source star HD 61071. The odd pattern of the nebulae is puzzling - I am assuming that it is due to surrounding dust. Examining the background stars, it is not obvious to me that there is significant dust in this region.

Sidney van den Bergh published his vdB catalog of reflection nebulae in 1966. It was later expanded by one for a total of 159. The collection encompassed all reflection nebulosity visible on the Palomar Sky Survey north of -33 degrees latitude. My Astrobin vdB Collection, which is about 85% complete, is here.

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.
