Dark nebulae halfway between lambda Cen and Carina nebula (Alexandr Zaytsev)

Dark nebulae halfway between lambda Cen and Carina nebula

1h30min of integral Ha exposure of a set of dark nebulae located halfway between lambda Cen and Carina nebulae - captured remotely using Telescope #3 (ASA-N D = 0.5m f/3.8, FLI ProLine 16803) system of ChileScope on Mar 15, 2024.

Two peculiar small DSOs showed up in the FOV - the first one in the upper left corner, shown in 150% of original scale in the cropped image below:

and the second one on the top right side of the FOV, also shown at 150% of original scale in the cropped image below:

The first object is likely the PN G290.7-01.7 [1] - the peculiar 3 arm shape suggest that there may be a multiple star system at play there like in the case of Tau V1025 [2].

The second one is likely associated with two cataloged objects - an IR source [3] and the HII region [4].

More detailed views for these two objects obtained with Chilescope T1 instrument is available under [5, 6].

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.
