Ced 122: Emission nebula, dark nebula lanes and star field in Centaurus

Site:

Lo Barnechea, Chile

Seeing 5/5 + Transparency 4/5

Images:

Ha/Ha/CLS/OIII composition

15/15/15/15 subs @ 300 sec each

225 minutes total exposure

20 darks and 15 flats per channel

Comments:

This object is part of the Cedeblad's catalog of galactic nebulosities. Many of these obtects are not included in the NGC or IC catalog and yet, are extremely beautiful. It is fair to say that this one looks like a very rich star field with dark nebula lines filling the entire frame, rather than an emission nebula as it is described in different sources. There are a few faint nebulosities but may require more exposure time to reveal themselves. My mount was guiding very poorly last night at an average RMS of 1,4 sec which ended up providing some fuzzies instead of round stars and truly detailed nebulosities. I did my best to process with deconvolution in SIRIL and postprocessing with GIMP.

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.
