M27 - The Dumbbell Nebula

I collected data on this last summer and was going to add to it this year but decided in the end I probably had enough to make a decent image out of it.

I used a combination of short / long exposures to put together a blended composite image of the very bright core and much fainter outer structure. The Ha stacks were used as a luminance layer for both the core and outer regions. The ImageBlend and SelectiveColourCorrection scripts in Pixinsight were very useful to aid the assembly of the image. A short amount of RGB data was used for the stars.

M27 is one of the brightest planetary nebulae in the sky and (the bright core at least) is visible in binoculars. It lies around 1000 light years away from us. Planetary nebulae are formed around stars in the last stages of life as they shed their outer layers and is a fate expected to befall our own sun a few billion years from now.

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.
