Spaghetti Nebula - SH2-240 / Simeis 147 in HOO

Decay and rebirth, on a cosmic scale.

The tiny nebula in the far right of this first image is designated SH2-242 (Sharpless 242). Nebulae like this one are home to new star formation.

The other (much larger) object in this image is SH2-240, or the 'Spaghetti Nebula". It is an example of a supernova remnant, or SNR. In one image we have an entire circle of life, from star birth to eventual death.

What's truly beautiful is how the life and death of a star actually creates so many new materials that would never have existed without this process. Our telescopes and special filters can help us see charged gas particles like hydrogen and oxygen, but there are so many other materials ejected by stars that are harder to see, such as carbon and heavy metals. Eventually these will get caught up and fused in the formation of new stars and solar systems. They may lead to new planets... and maybe even living organisms. It's an amazing process of continual rebirth.

I'm now up to almost 30hrs of exposure on this object. I'm shooting this as a 2-panel mosaic, using a William Optics RedCat51 and a 2600MC camera, plus a Radian Triad Ultra filter. I use APP to stack and then separate the data into Hydrogen and Oxygen channels before re-assembling in Photoshop as an HOO palette image.

Captured from my Bortle 8 location near suburban Toronto. I hope you enjoy it. Clear skies!

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.
