NGC3132

NGC3132 = Caldwell74 = PK272+12.1 is a planetary nebula at a distance of about 2000LJ from Earth with an expansion velocity of about 10miles/sec. it is often called Southern Ringnebula or also Eight Burst Nebula in the constellation Vela. There are 2 central stars - one larger than the other, the larger one is clearly visible and very bright, the other, smaller but hotter one is the reason for the emission nebula, both are White Dwarfs with a temperature over 100k Kelvin. The smaller one is an intensive source of UV radiation which causes the ionized gases in the vicinity to fluoresce and radiate, even in the visible part of the spectrum.
An interesting object, but one needs a very long focal length to get it imaged properly - for this image, that focal length was 6800mm at f/6.8 and only one single session of 4x2x600" for LRGB was acquired. The processing was not too easy but the result is still quite good IMO.

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.
