Centaurus A

Images from 2 nights, 8th and 9th of April. Full Moon was the 6th April. In the past I would image narrowband around full moon, but with my new OSC camera this wasn't an option. What to do? The forecast was completely clear both nights so too good to waste. Centaurus A was ideally placed for a full nights imaging, transiting just after midnight, and maybe it was bright enough to work with so much moonlight. Unfortunately on the 8th it was only about 20 degrees from the moon so I didn't expect much. This night did have a very strong gradient across the frame but the second night was better and Local Normalization in WBPP handled this remarkably well. I was pleasantly surprised with the outcome, and can just see the blue relativistic jet around 8 o'clock but no trace of the red jet further out.

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.
