NGC 3372 The Eta Carina Nebula in SHO

Located approximately 8500 light years in Carina resides a spectacularly violent HII region. Nestled in that is the second largest star in our galaxy which is destined for a short but furious life.
Actually a double star in an accelerating collapse cycle which, should it go super dooper nova, would be visible in daytime. When the dust settles this region would be be gone.
Always a visual treat through a big wide field 31 Nagler eyepiece but the Homunculus is mind boggling on a good night with a small eyepiece on good 20" with a 3-6mm Nagler Zoom.

Of all the objects I have viewed in the Southern Sky, nothing comes close to demonstrating so clearly that the dynamic range of the human eye is better than most sensors.

The mottled lobs and jets are very distinct whereas sensors drown them out. Finding a good image of the Homunculus is, or was, not easy. Maybe a web cam on a big dob. Strange that few give it a red hot go on larger instruments. The entire nebula would have looked very different before the Great Eruption in the 1840s surrounded Eta Carinae with dust, drastically reducing the amount of ultraviolet light it put into the nebula. Over the last 20 years Eta Carina has brightened significantly as dust from the 1840's eruption clears and is now easily visible to the naked eye.

This is a perfect candidate for the Red Cat 71. On the AM5 with ZWO EAF and ASI Air it is really set and forget (almost). One more good night bumped me up to 7 hours of data which is always a good thing when the object has so much detail and such really wide dynamic range.

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.
