Revision title: NGC 3576 Statue of Liberty Nebula revised

Only my second attempt of this wonderful emission nebula NGC 3576 in Carina
First time was with my 2600MC OSC back in 2022
Captured over 2 nights under Bortle 8 skies and a full moon , the Antlia 3nm filters were really put to the test . I was very happy with the level of detail using 3 min subs however star cores were still blown out to some degree . 2 min subs may have been a better option. One thing I’m finding with the 2600MM , you don’t need really long subs when using medium sized Newt , even with Narrowband filters , this camera is so sensitive.

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.
