I stumbled upon this on Stellarium when I was scrubbing it for targets to shoot after 3am till sunrise. While I was surprised to see this southern target, I was not very motivated to set it up given how low it was (25 degrees to 15 degrees for 90 minutes). See image revision C.

As any responsible astrophotographer would do, I ended up collecting data, haha. I knew I could not get Ha given it is getting lower and lower so just ran with LRGB. After squirreling upto 7-8 subs per channel for several nights, stacked and took this data through. From the looks of it, I suppose I am not missing out on Ha.

On the lower right, I seem to have picked up some reflection, but given the less number of subs I got, I could not "bury" it fully and I do not want to heavily crop this image either. So left it as-is.

Hope you like this result. Clear skies!

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.
