PP 81

This object (PP 81; Parsamian & Petrosian; 1979) is certainly a rather rarely photographed one. The small reflection nebula is located at the upper end of the constellation Lupus, embedded in the dark nebula complex Barnard 228. What I particularly like, apart from the reflection nebula, is the structure of dark nebulae directly surrounding it. They remind me a little of a Phoenix carrying a flame in its chest. But enough about that, I don't actually like these figurative object names very much - let everyone make up their own mind here.

This time I invested a little more than usual in the RGB frames to give the dark nebulae "some color". On the other hand, the luminance fell somewhat by the wayside (I threw some away due to the seeing), but the almost 4 hours were enough. And since I'm not a very patient photographer, I'm already looking for other 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.
