47 Tucanae Globular Cluster in RGB

47 Tucanae, or 47 Tuc (also designated NGC 104) is a globular cluster located in the constellation Tucana about 15,000 light years away from Earth and is about 120 light years in diameter.
47 Tuc can be seen with the naked eye, with an apparent magnitude of 4.1 and appears about 44 arcminutes across. It is the second brightest globular cluster after Omega Centauri, and telescopically reveals about ten thousand stars, many appearing within a small dense central core.

I was lucky enough to meet up with Peter Read of SDM Telescopes when he was delivering and finishing the setup an new 18" DOB (collimation at the eyepiece!) at the Astronomical Society of New South Wales' Wiruna property on a very good night as few years back. I offered a warm 8mm Ethos from my pocket and he asked if I had anything more powerful, so I dug out a 3mm Radian and we dived into into the heart of 47 Tucanae ... it looked like an open cluster! Unbelievable optics on an amazing mount with an exquisite Mark Sutching mirror.

All fresh data of variable quality over the last week but beggars can't be choosers and there was a new Pixinsight update to work with. GHS, BlurXTerminator and NoiseXterminator on a tight leash leash and creating lightness masks with ACDNR makes a huge difference. Needless to say less is more and my first run looked like a regurgitated dog's breakfast so back to the SPCC linear image and now a result I can live with until I can get more clean data. At this time of year it is quite low and I have a huge tree adjacnet to the SCP to dodge but I hope to go bush in the new year and will look for a deep run under Bortle 2 skies on this magnificant object.

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.
