Centaurus A

I decided to use up my final credit with Chilescope on Luminance imaging of three southern galaxies (Cen A, Antennae and M83). The intention was to combine the good seeing of Chilescope with the mediocre seeing of my home observatory.

I have previously posted M83 to Astrobin, and this is the Cen A image. Can A is a brute to post-process, and encompassing the dynamic range form the inner dust lane (with its colours and structure) to the outer polar ring is well beyond my capabilities. [I suspect it may be easier in Photoshop, but my feeble attempts with masks in PI didn't work.]

In this case I have chosen to focus mostly on the inner dust lane with a tighter crop, but I also include a wider field view with the luminance layer grossly manipulated - so the shells and polar ring are more apparent.

L: 17 x 600sec
R: 30 x 300sec
G: 27 x 300sec
B: 24 x 300sec

Data taken with TS Hypergraph 8 @ Speargrass Flat Observatory (seeing 5arcsec) nd ASA500 at Chilescope (seeing 2.5arcsec)

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.
