M27, The Dumbbell Nebula in HOO

M27 was the first planetary nebula discovered by Charles Messier in 1764. The central star is a white dwarf and this explosion is similar to the one our Sun will produce at the end of his life. It is situated in Vulpecula at 1360 l.y. (Wikipedia).

This nebula has a high dynamic range which makes it difficult to process. There are a few risks when processing it, compressing the core will give it a flat appearence with no 3D structure and overstretching the data for the faint halo can increase the noise too much. I tried to keep the globular shape while revealing the central structures. Lots of trials with the palette (I am really no good at HOO, can't wait for the SHO nebulae) and I finally opted for a non-linear mix, I generally mix everything in linear. Somehow the SNR looked better. The stars are in natural RGB color. Shot on multiple nights from April 13 - May 12.

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.
