M27 - Dumbell Nebula (Revisited with Antlia ALP-T)

M27 is a planetary nebula in the constellation Vulpecula and is estimated to be about 1,360 light years away.
This object was first discovered by Charles Messier in 1764.

104x180s Lights (Taken over 2 nights), calibrated with flats, darks and flat-darks.

This image was taken in my Bortle 7 backyard and processed in Pixinsight.

This was my first target taken with the Antlia ALP-T dual-narrowband filter and the target provided a stunning example of how much this filter helps in light polluted skies. The "wings" and expanded halo around the nebula were out of reach until I added the Antlia ALP-T.

Due to the significant difference in brightness between the faint wings and the core of the nebula, I had to use two lightness masks during stretching to protect the dumbell itself from being blown out. Stars and nebula were processed separately thanks to the amazing StarNet2 tool.

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.
