Omega Centauri

Another popular target, so other apology to my AB friends for posting a too-familiar image. In this case, its Omega Centauri by full moon.

I have previously imaged at 500mm focal length, I wanted to see how much more detail a larger scope with a longer focal length would give me. I also chose to short(ish) exposure to help with star cores. Possibly I should have taken more subs, but my elderly Mac is really starting to struggle with WBPP, so I decided to keep it down to a manageable number.

Overall, I am quite happy with the final result. The resolution at the centre is quite good - for my site - and I didn't push the saturation too much as I like the more muted colours. The contrast may be a little heavy-handed, but I do like the impact it creates with the globular cluster.

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.
